Multiplication & Division

Master the basics of repeated groups and equal shares

What is Multiplication?

Multiplication is a fast way to add equal groups! Instead of adding 4 + 4 + 4, we can say "3 groups of 4" or 3 × 4 = 12. Let's explore how multiplication works with groups of objects.

4 Groups of 3 Apples 3 3 3 3 4 × 3 = 12 4 groups of 3 equals 12!

Try This!

Count the dots: What is 2 groups of 5? Draw 2 groups with 5 dots in each group. How many dots altogether?

Answer: 2 × 5 = 10 dots

Fun Fact! We use multiplication every day! When you put 3 chairs at each of 4 tables, that's 3 × 4 = 12 chairs total. Multiplication helps us count large groups super fast!

What is Division?

Division is the opposite of multiplication! It's when you share something equally among groups. If you have 12 cookies and want to share them equally among 3 friends, division helps you find out how many cookies each friend gets. 12 ÷ 3 = 4 cookies for each friend!

Division uses the ÷ symbol (called the division sign). The big number you're dividing goes first, and the smaller number tells you how many groups to make or how many to share with.

You can think of division in two ways: sharing (dividing 12 cookies among 3 friends) or grouping (making groups of 4 from 12 things). Both give the same answer!

12 Cookies ÷ 3 Plates 4 each 4 each 4 each 12 ÷ 3 = 4 shared equally = 4 each

Real-Life Example

You have 15 candies and 5 friends. If you share equally, each friend gets 15 ÷ 5 = 3 candies

Remember: 12 ÷ 3 = 4 means "12 shared into 3 groups gives 4 in each group"

Multiplication Tables

A multiplication table helps us memorize multiplication facts quickly. When you learn the tables, you can multiply faster without counting on your fingers every time! Let's start with the 2s, 5s, and 10s tables because they're easiest to learn.

Times Table (1-5) × 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 2 4 6 8 10 3 6 9 12 15 4 8 12 16 20 5 10 15 20 25

Notice a pattern in the 10s table? 1 × 10 = 10, 2 × 10 = 20, 3 × 10 = 30. When you multiply by 10, you just add a zero! The 5s table ends in either 5 or 0. These patterns help you learn faster!

Quick Tips for 2s

2 × 3 = 6

2 × 4 = 8

2 × 5 = 10

2 × 6 = 12

Quick Tips for 5s

5 × 2 = 10

5 × 3 = 15

5 × 4 = 20

5 × 5 = 25

Pro Tip: Practice your multiplication tables every day! You can use your fingers, count objects, or draw pictures to help you remember.

Problem Solving

To solve multiplication and division word problems, follow these steps: First, read the problem carefully and understand what you need to find. Then, decide if you need to multiply or divide. Finally, write the number sentence and solve it!

Look for clues in the problem! Words like "groups," "each," "total," and "altogether" mean you should multiply. Words like "share," "divide," "split," and "each gets" mean you should divide.

5 Friends with 3 Stickers Each5 × 3 = 15total stickers15 in all

Example 1: Multiplication Problem

Problem: Sarah has 3 baskets with 4 apples in each. How many apples does she have altogether?

Solution: 3 × 4 = 12 apples

We multiply because there are groups (3 baskets) with the same number in each group (4 apples).

Example 2: Division Problem

Problem: A baker has 20 cookies and wants to put them equally into 4 boxes. How many cookies go in each box?

Solution: 20 ÷ 4 = 5 cookies in each box

We divide because we're sharing equally among groups (4 boxes).

Problem-Solving Steps: 1) Read carefully 2) Find the clue words 3) Decide: multiply or divide? 4) Write the number sentence 5) Solve and check your answer

Doubling and Halving

Doubling means multiplying by 2. Halving means dividing by 2. These are really handy mental maths tricks!

Double 15 = 15 × 2 = 30

Double 13 = 13 × 2 = 26

Half of 26 = 26 ÷ 2 = 13

Half of 50 = 50 ÷ 2 = 25

Trick: To double a tricky number, split it! Double 15 = double 10 + double 5 = 20 + 10 = 30. To halve, split too! Half of 26 = half of 20 + half of 6 = 10 + 3 = 13.

Arrays

An array is a way to arrange objects in equal rows and columns. Arrays help us see multiplication!

If you put stickers in 3 rows with 4 in each row, you have an array of 3 × 4 = 12 stickers.

🔵🔵🔵🔵
🔵🔵🔵🔵
🔵🔵🔵🔵

3 rows × 4 columns = 12 items. You can also read it as 4 × 3 = 12 (same answer!).

Arrays are everywhere: eggs in a carton (2 × 6 = 12), chocolate bars in a box, seats in a cinema!

Skip Counting Patterns: Skip counting is counting in jumps of the same number. It's the foundation of times tables!
By 2s: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
By 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
By 4s: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
By 5s: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
By 10s: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

Fun with Multiplication!

Did you know that multiplication can be found everywhere in everyday life? When you arrange things in rows and columns, you're using multiplication! Sports players wear numbers that multiply. Games have points that multiply when you're doing well!

Arrays are pictures that show multiplication. An array is a group of objects arranged in rows and columns. If you have 3 rows with 4 objects in each row, that's 3 × 4 = 12 objects total. You can see this in egg cartons (12 eggs in rows), game boards, and even on a calendar!

4 × 6 Array Pattern4 rows × 6 columns = 24 dots

You can also skip count to multiply! Skip counting by 2s goes: 2, 4, 6, 8, 10, 12... This is the same as the 2s multiplication table! Try skip counting by 5s: 5, 10, 15, 20, 25, 30... These are all multiplication facts!

Skip Counting by 2s

2, 4, 6, 8, 10

= 1×2, 2×2, 3×2, 4×2, 5×2

Skip Counting by 5s

5, 10, 15, 20, 25

= 1×5, 2×5, 3×5, 4×5, 5×5

Fun Fact: Arrays help you understand that 3 × 4 = 4 × 3! Both arrangements have 12 items total, just rotated differently.

Fractions

Learn to divide things into equal parts

What are Fractions?

A fraction is a part of a whole! When we divide something into equal pieces, each piece is a fraction. Let's say we cut a pizza into 8 equal slices. Each slice is 1/8 of the pizza. The bottom number tells us how many equal pieces. The top number tells us how many pieces we have!

Pizza Fractions 1/4 1 = part taken 4 = parts total

Fraction Labels

1/2 = 1 out of 2 equal pieces (half)

1/4 = 1 out of 4 equal pieces (quarter)

3/4 = 3 out of 4 equal pieces

Remember: Fractions must have equal pieces! If you cut a cake into unequal pieces, those aren't fractions—they're just pieces!

Equal Fractions

Did you know that different fractions can represent the same amount? 1/2 is the same as 2/4, and 2/4 is the same as 3/6! These are called equivalent fractions or equal fractions. They look different, but they mean the same thing.

Imagine a chocolate bar divided in half - you get 1/2. Now imagine the same chocolate bar cut into 4 pieces - if you take 2 pieces, you have 2/4, which is the same as 1/2! The chocolate bar isn't bigger or smaller; it's just cut differently.

Equivalent Fractions1/2=2/4

You can make equal fractions by multiplying or dividing the top and bottom numbers by the same number. If you multiply 1/2 by 2, you get 2/4 (same amount, just more pieces!)

Building Up

1/2 = 2/4

1/2 = 3/6

(More pieces, same amount)

Simplifying

2/4 = 1/2

3/6 = 1/2

(Fewer pieces, same amount)

Secret Trick: If you can draw both fractions and they shade the same amount, they're equal fractions!

Comparing Fractions

Sometimes you need to figure out which fraction is bigger! Is 1/2 bigger than 1/4? Which is larger: 3/4 or 2/4? When you compare fractions, you're asking "which part is bigger?"

Here's a helpful rule: When the denominators are the same, look at the numerators! If you have 3/4 and 2/4, the 3/4 is bigger because 3 is bigger than 2. You're comparing the number of pieces you have.

When the denominators are different, it helps to draw pictures! A picture of 1/2 and a picture of 1/4 will clearly show that 1/2 is larger, because the 1/2 piece takes up more space.

Comparing Fractions1/31/31/31/3 is shaded1/31/31/32/3 is shaded2/3 > 1/3

Comparing Same Denominators

Which is bigger: 2/6 or 5/6?

Since the denominators are the same (both 6), compare the numerators: 2 vs 5. Since 5 > 2, then 5/6 is bigger!

Comparison Symbols: < means "less than", > means "greater than", = means "equal to"

Adding Fractions

You can add fractions together, just like you add whole numbers! If you have 1/4 of a pizza and your friend has 2/4 of the same pizza, together you have 3/4 of the pizza. You just add the numerators!

Here's the rule: When the denominators are the same, add the numerators and keep the denominator. So 1/4 + 2/4 = 3/4. The pieces stay the same size; you're just counting more pieces total!

If the denominators are different, you need to find equal fractions with the same denominator first. This is called finding a common denominator. Then you can add them!

Adding Fractions1/4+1/4=2/4 = 1/2

Try These!

1/6 + 3/6 = 4/6

2/5 + 1/5 = 3/5

3/8 + 2/8 = 5/8

Remember: Only add the numerators! Keep the denominator the same. The pieces don't change size when you add.

Fractions of Amounts

Now that you know what fractions are, let's learn how to find a fraction of a number. This is a super useful skill — like finding half of a pizza or a quarter of your pocket money!

The Golden Rule

To find a fraction of a number, divide by the bottom number (denominator).

Then multiply by the top number (numerator).

For unit fractions (where the top is 1), you just divide!

Finding ½ (One Half)

½ of 10 → Divide 10 by 2 = 5

½ of 20 → Divide 20 by 2 = 10

½ of 8 → Divide 8 by 2 = 4

Think of it as sharing equally between 2 people!

Finding ¼ (One Quarter)

¼ of 12 → Divide 12 by 4 = 3

¼ of 20 → Divide 20 by 4 = 5

¼ of 8 → Divide 8 by 4 = 2

Think of it as sharing equally between 4 people!

Finding ⅓ (One Third)

⅓ of 9 → Divide 9 by 3 = 3

⅓ of 15 → Divide 15 by 3 = 5

⅓ of 12 → Divide 12 by 3 = 4

Think of it as sharing equally between 3 people!

Non-Unit Fractions

For fractions like ¾ or ⅔, first divide, then multiply:

¾ of 12: 12 ÷ 4 = 3, then 3 × 3 = 9

⅔ of 15: 15 ÷ 3 = 5, then 5 × 2 = 10

Real-World Example: There are 24 children in a class. ¼ of them wear glasses. How many? 24 ÷ 4 = 6 children wear glasses!

Fun Fraction Activities

Fractions are used in cooking, sports, music, and games! When a recipe says "add 1/2 cup of flour," you're using fractions. When a player makes 3/4 of their free throws in basketball, that's fractions. Learning fractions helps you understand real-world situations.

You can find fractions everywhere! In a classroom of 24 students, if 8 like soccer, that's 8/24 (or simplified, 1/3) of the class. If half the class likes reading, that's 12/24 (or 1/2). Fractions help us talk about parts of groups!

Fraction Shapes1/21/41/3

Try this fun activity: Take a pizza (real or pretend!) and cut it into different numbers of slices. Count how many slices you have. If you eat 2 slices out of 8, you ate 2/8 (or 1/4) of the pizza! You can explore fractions with pies, candy bars, or even by folding paper!

Music Fractions

In music, we have whole notes, half notes (1/2), and quarter notes (1/4)!

Money Fractions

A coin worth 25 rupees is 1/4 of 100 rupees. A 50-rupee note is 1/2 of 100 rupees!

Fun Challenge: Find 5 things in your house that show fractions! A clock (12 hours), a pizza box, a chocolate bar, a measuring cup, or a game board!

Geometry

Explore shapes, angles, and lines

Understanding Angles

An angle is formed where two straight lines meet at a point. Angles can be small (acute), perfect corners (right), or big (obtuse). Let's explore the three main types of angles!

Types of Angles Acute <90° Right =90° L-shape Obtuse >90° Wide

Right Angles Everywhere! Look around your classroom. Do you see a right angle? Corners of doors, windows, desks, and books all have right angles! They look like perfect squares at the corners.

Spot the Angles

Can you find these angles in your classroom?

  • Right angle: Corner of a book or desk
  • Acute angle: Hands of a clock at 1:00
  • Obtuse angle: Hands of a clock at 10:00

Types of Lines

Lines are the basic building blocks of geometry! A straight line goes on forever in both directions. A line segment is a part of a line with two endpoints - like a pencil or a stick. A ray has one endpoint and goes on forever in one direction, like a light ray from a flashlight.

Lines can relate to each other in different ways. Parallel lines never meet, even if you extended them forever. Imagine railroad tracks - the two rails stay the same distance apart and never touch. Perpendicular lines meet at right angles (90 degrees), like the lines in a grid or tic-tac-toe board.

Intersecting lines are lines that cross each other at some point. They don't have to be perpendicular; they just have to meet. Think about roads crossing in a city - they intersect at intersections!

Types of Lines Parallel Never meet Perpendicular Right angles Diagonal Slanted

Line Types

Line: Goes forever both ways

Ray: One endpoint, goes forever

Segment: Two endpoints

Line Relationships

Parallel: Never meet

Perpendicular: Meet at 90°

Intersecting: Cross somewhere

Real-World Examples: Parallel lines: Power lines, road lanes. Perpendicular lines: Window panes, crossroads. Intersecting lines: Scissors handles, road intersection.

Perimeter

Perimeter is the distance around the outside of a shape. If you walked around the edge of your classroom and counted your footsteps, that would be the perimeter! To find the perimeter, you add up the lengths of all the sides.

For a rectangle with sides that are 5 and 3 units long, the perimeter is 5 + 3 + 5 + 3 = 16 units. Notice that opposite sides of a rectangle are equal! For a square where all sides are 4 units, the perimeter is 4 + 4 + 4 + 4 = 16 units, or simply 4 × 4 = 16 units.

You can measure perimeter using any unit: inches, centimeters, feet, or even steps! Perimeter is useful for things like building a fence around a yard, putting a border around a picture, or measuring how much ribbon you need to go around a gift box.

Measuring Perimeter240 units120240 unitsPerimeter = 240 + 120 + 240 + 120 = 720

Finding Perimeter

Step 1: Measure all the sides

Step 2: Add all the measurements together

Step 3: Write the perimeter with the unit (cm, m, etc.)

Quick Tip: For a rectangle: P = (length × 2) + (width × 2). For a square: P = side × 4

Symmetry

Symmetry means something is balanced and matches on both sides of a line! If you fold a piece of paper in half and both sides match perfectly, that paper is symmetrical. The fold line is called the line of symmetry.

Many things in nature are symmetrical! A butterfly has one line of symmetry down the middle - if you fold it, both wings match. A flower often has multiple lines of symmetry. Your face is nearly symmetrical - the left and right sides are almost mirror images!

Some shapes have one line of symmetry, some have many, and some have none. A square has 4 lines of symmetry (vertical, horizontal, and both diagonals). A rectangle has 2 lines of symmetry (vertical and horizontal). A scalene triangle might have no lines of symmetry.

Lines of SymmetryLine ofSymmetry

Shapes with Symmetry

Square: 4 lines

Rectangle: 2 lines

Isosceles triangle: 1 line

Circle: Infinite lines!

Finding Symmetry

1. Fold the shape

2. Do both halves match?

3. The fold line is the line of symmetry

4. Try different fold directions

Nature's Design: Look for symmetry in leaves, flowers, insects, and animals. Nature loves symmetry because it's strong and beautiful!

3D Shapes

So far we've learned about flat (2D) shapes. Now let's explore 3D shapes — shapes that have depth! They aren't flat like a drawing; they pop out and have faces, edges, and vertices.

2D vs 3D

2D shapes are flat. They have length and width but no depth. Think of a drawing on paper — a square, triangle, or circle.

3D shapes have length, width, AND depth. They take up space. Think of a box, a ball, or a tin can — you can hold them!

Parts of 3D Shapes

Face — A flat surface on a 3D shape. A cube has 6 faces.

Edge — Where two faces meet, like a line. A cube has 12 edges.

Vertex (corner) — Where edges meet at a point. A cube has 8 vertices. (Plural: vertices)

Common 3D Shapes

Cube — 6 square faces, 12 edges, 8 vertices. Example: a dice, a Rubik's cube.

Cuboid — 6 rectangular faces, 12 edges, 8 vertices. Example: a cereal box, a brick.

Sphere — 1 curved face, 0 edges, 0 vertices. Example: a football, a tennis ball, a globe.

Cylinder — 2 flat circular faces + 1 curved face, 2 edges, 0 vertices. Example: a tin can, a toilet roll tube.

Cone — 1 flat circular face + 1 curved face, 1 edge, 1 vertex (the point). Example: an ice cream cone, a party hat.

Pyramid — A flat base (often a square) + triangular faces meeting at a point. A square pyramid has 5 faces, 8 edges, 5 vertices. Example: Egyptian pyramids.

Triangular Prism — 2 triangular faces + 3 rectangular faces = 5 faces, 9 edges, 6 vertices. Example: a Toblerone box.

Quick Reference Table:
Cube: 6 faces, 12 edges, 8 vertices
Cuboid: 6 faces, 12 edges, 8 vertices
Sphere: 1 face, 0 edges, 0 vertices
Cylinder: 3 faces, 2 edges, 0 vertices
Cone: 2 faces, 1 edge, 1 vertex
Square Pyramid: 5 faces, 8 edges, 5 vertices
Triangular Prism: 5 faces, 9 edges, 6 vertices

3D Shapes in the Real World

Look around you — 3D shapes are everywhere!

A football is a sphere. A book is a cuboid. A traffic cone is a cone. A tin of beans is a cylinder. A dice is a cube. The roof of a house can be a triangular prism!

Nets of 3D Shapes

A net is what a 3D shape looks like when you unfold it flat. If you cut along the edges of a cardboard box and flatten it, you get the net of a cuboid!

A cube's net has 6 squares joined together. You can fold it up to make the cube again. There are actually 11 different nets that can fold into a cube!

Fun Geometry Games

Geometry isn't just for math class - it's used in art, design, architecture, and games! Tangrams are an ancient Chinese puzzle made of 7 geometric pieces. You can arrange these pieces to make animals, people, houses, and hundreds of other shapes. Every solution uses all 7 pieces exactly once!

Pattern blocks are colorful shapes that fit together to create beautiful designs and patterns. By exploring how different shapes fit together, you learn about angles, sides, and symmetry. You can create tessellations - patterns that cover a surface with no gaps or overlaps, like a tiled floor!

Even video games, toys, and sports use geometry! A soccer ball is made of pentagons and hexagons. A basketball hoop has a circular rim. A chess board is a grid of squares. Learning geometry helps you understand the world better!

2D Shapes Triangle 3 sides Square 4 equal sides Rectangle 4 sides, 2 pairs Pentagon 5 sides Hexagon 6 sides Circle Curved

Try This!

Create a tessellation with pattern blocks or by drawing triangles and squares. Can you cover an area with no gaps or overlaps? Experiment with different arrangements!

Geometry in Sports: Tennis ball - fuzzy sphere; Soccer field - rectangle with angles; Football - oval/ellipse; Basketball hoop - circle. Can you find other geometric shapes in sports?

Data & Graphs

Tally Marks

Tally marks are a quick way to count and keep track! We draw a line for each item, but when we reach 5, we draw a diagonal line through 4 lines. This makes groups of 5 that are easy to count!

Tally ChartApples:5Bananas:4Grapes:3Total

Practice Exercise

Count these tally marks:

How many tallies do you see? Count by fives: One group of 5 plus 3 more = 8 items!

Why use tallies? Tally marks are fast and easy to see at a glance! Grouping by 5 makes counting large amounts super quick. Teachers use tallies when taking attendance or counting votes!

Bar Graphs

A bar graph is a picture that uses bars (rectangles) to show information. Each bar represents a different category, and the height of the bar shows how many items are in that category. Bar graphs make it easy to compare amounts at a glance!

When you look at a bar graph, start by reading the title to understand what information is being shown. Look at the labels on the sides and bottom. The numbers on the side (called the y-axis) tell you the scale - how many items each mark represents. The labels on the bottom (called the x-axis) tell you the categories.

Bar graphs can be vertical (bars go up and down) or horizontal (bars go left and right). Either way, taller or longer bars mean more items. You can use bar graphs to show favorite colors, sports, foods, or anything else you want to compare!

Add labels and title

Remember: All bars should have the same width. The only thing that changes is the height! This makes comparing fair and accurate.

Pictograms

A pictogram is a graph that uses pictures or symbols to show information! Instead of bars, you use small pictures related to what you're counting. For example, if you're counting apples, you use little apple pictures. If you're counting cars, you use little car pictures. Each picture usually represents one or more items.

Pictograms are fun and easy to understand, even for very young children! You can quickly see which category has more by counting how many pictures it has. They're also colorful and interesting to look at, which makes learning about graphs more enjoyable.

Sometimes one picture represents more than one item. A key tells you what each picture means. For example, one soccer ball picture might mean 5 goals scored. This is useful when you have large numbers - instead of drawing 100 pictures, you draw 10 pictures where each one means 10!

Pictogram Key: = 2 fruits Apples: = 6 Bananas: = 4 Oranges: = 5

Making a Pictogram

Step 1: Choose a picture for your data

Step 2: Count your information

Step 3: Draw rows for each category

Step 4: Use pictures to show the count

Step 5: Add a key explaining what each picture means

Fun Fact: "Picto" means picture and "gram" means drawing. So pictogram literally means "picture drawing!" That's a perfect description of what it is.

Reading and Interpreting Graphs

Reading a graph means understanding what information it shows and what that information means. To read any graph, follow these steps: First, read the title. Then look at the labels. Then study the data shown. Finally, answer questions about what you see.

When you read a graph, you can compare amounts ("Which has more?"), find the largest and smallest values, and see patterns in the data. You can also estimate values between marked points and make predictions based on the information shown.

Sometimes graphs trick you! Always check the scale carefully. A graph that starts at 0 looks very different from one that starts at 10. Always read the title and labels carefully so you understand exactly what's being shown.

Reading a GraphRedBlueGreenYellowCountColours

Tips for Reading Graphs

1. Title: What is this graph about?

2. Labels: What do the sides and bottom say?

3. Scale: Where does it start? What numbers are shown?

4. Data: What do the bars/pictures/points tell us?

Comparison Questions: Which is biggest? Which is smallest? How much more/less? Are any equal? What comes next if the pattern continues?

Fun Data Projects

Data collecting and graphing can be a fun activity! You can collect information about anything that interests you. How many students prefer hot lunch vs. cold lunch? What's the favorite color in your class? How many hours of sleep did each student get last night? These real-world questions lead to real data you can graph!

You can create a survey, collect tallies, and then make a graph to show your results. Share your graph with classmates and talk about what the data shows. Are there any surprises? Can you predict what would happen if you asked different questions or surveyed more people?

Think about data in your daily life! Weather data shows temperature and rainfall. Sports statistics track scores and player performance. Sales data shows what's popular in stores. News reports often include graphs to help explain information. Data is everywhere, and learning to read and create graphs helps you understand the world!

There are three main types of rocks: igneous, sedimentary, and metamorphic. Each type forms in a different way and has different properties. Let's discover what makes each rock type special!

Three Rock Types Igneous Formed by: cooling lava Sedimentary Formed by: layers pressing together Metamorphic Formed by: heat + pressure

Igneous

Forms from: Melted rock (magma) that cools

Example: Basalt, granite

Features: Very hard, shiny crystals

Sedimentary

Forms from: Layers of sand and shells pressed together

Example: Sandstone, limestone

Features: Soft, crumbly, found near water

Metamorphic

Forms from: Other rocks changed by heat and pressure

Example: Marble, slate

Features: Striped patterns, very hard

Rock Cycle Fun! Rocks change over millions of years. An igneous rock can become sedimentary, which can become metamorphic, which can melt and become igneous again. It's an endless cycle!

The Rock Cycle

Rocks are always changing! The Rock Cycle shows how rocks change from one type to another over millions and millions of years. This amazing cycle never stops. Rocks get broken down, pressed together, melted, and formed again in a never-ending circle of change.

The Rock Cycle Igneous from cooled lava Sedimentary pressed layers Metamorphic heat + pressure Weathering & layering Heat + pressure Melting & cooling

Here's how the Rock Cycle works: Rock from mountains gets broken down by wind and rain. These pieces wash into the ocean where they settle and get pressed together to make sedimentary rocks. Heat and pressure deep in the Earth changes these rocks into metamorphic rocks. When rocks get pushed even deeper, they melt into magma. When the magma cools, it becomes igneous rock again! The cycle never stops.

⏰ Time Travel: The Rock Cycle takes MILLIONS of years! A rock that exists today might have been a different type of rock millions of years ago, and could become another type in millions of years in the future.

How Rocks Get Broken Down

Rocks break apart slowly over time. Rain, ice, wind, and roots all work together to break rocks into smaller pieces. This process is called weathering. When rocks get broken into pieces and moved to a new place by water or wind, it's called erosion. These pieces can become sand on a beach or dirt on a hillside!

Fossils: Windows to the Past

Fossils are the remains of plants and animals that died millions of years ago. They got buried under layers and layers of rock and sediment. By studying fossils, scientists can learn what kind of creatures and plants lived on Earth long ago. Fossils are like a time machine that shows us history!

How Fossils Form Stage 1 Animal dies Sinks under water or mud Stage 2 Buried in layers Pressure & minerals form Stage 3 Becomes rock Fossil embedded in solid rock Stage 4 Fossil found! Scientists dig and study it
🦴 Amazing Discovery: Some fossils are so detailed that scientists can see the exact bumps and scratches on an ancient creature's bones! Fossils help us learn about dinosaurs, ancient fish, and plants that lived millions of years ago.

Types of Fossils

Scientists find different kinds of fossils. Some fossils are actual bones or shells preserved in rock. Other fossils are molds or casts – these happen when an animal's body leaves an empty space in rock, or when that space fills with minerals. Footprints and tracks in ancient mud that hardened to rock are also fossils! Each type tells us something special about life in the past.

Paleontologists are scientists who study fossils. They dig carefully in rocks and dirt to find fossils without breaking them. Then they clean them gently and study them to learn what kind of creature or plant it was, how old it is, and what it tells us about Earth's history.

Soil: The Earth's Treasure

Soil is not just dirt – it's alive! Soil is a mixture of tiny rock pieces, dead plants and animals, water, air, and billions of living creatures. Soil is super important because plants grow in soil, and we need plants for food and clean air. Let's explore what makes soil special!

Soil Layers (Cross-Section) Topsoil (Dark, rich in nutrients & plants) Subsoil (Lighter brown, fewer nutrients) Broken Rock (Grey rock fragments) Bedrock (Solid rock underneath)

What's in Soil?

Soil has four main parts working together. First, there are tiny pieces of rock – some as small as dust! Second, there's organic matter, which is dead plants and animals that break down into nutrients. Third, there's water that plants drink. Fourth, there's air that plant roots and soil creatures need to breathe.

Sand

Large particles that let water drain quickly. Good for plants that like dry soil.

Silt

Medium particles that hold some water. Great for most plants!

Clay

Tiny particles that hold lots of water. Can be hard for roots to push through.

🌱 Life in Soil: One handful of soil contains MORE living creatures than there are people on Earth! Bacteria, fungi, worms, and bugs all live in soil and help plants grow healthy and strong.

Weathering & Erosion

Rocks seem indestructible, but over thousands and millions of years they slowly break apart into smaller pieces. This process is called weathering. Once rocks break into smaller bits, wind and water carry those pieces away — that's called erosion. Together, weathering and erosion shape our landscape: carving valleys, wearing down mountains, and creating the soil we grow food in.

Three Types of Weathering

Water Weathering

Water seeps into tiny cracks in rocks. When it freezes, it expands like ice in a bottle and splits the rock apart. Rain also slowly dissolves some rocks like limestone.

Wind Weathering

Wind carries sand and grit that scrape against larger rocks. Over time this sandblasting wears rocks smooth or carves them into amazing shapes.

Living Weathering

Plant roots push into cracks and force rocks apart as they grow. Burrowing animals and tiny organisms also help break rocks down bit by bit.

Amazing Erosion! The Grand Canyon in America was carved by the Colorado River over millions of years. Water erosion slowly wore away layer after layer of rock, creating a canyon over 1 mile deep! Sea cliffs also get smaller each year as waves crash against them, breaking off pieces of rock.

Rocks in Our Daily Life

Rocks are everywhere in our daily lives! We use rocks to build houses, make roads, create tools, and even to make things we wear. Let's discover how important rocks are to people and our world.

My Rock Collection Granite Igneous Quartz Mineral Obsidian Igneous Hematite Mineral Sandstone Sedimentary Jade Metamorphic Amethyst Mineral Pyrite Mineral How to Identify Rocks Colour — unique to each rock Hardness — can you scratch it? Lustre — shiny, glassy, or dull? Texture — smooth or rough? Weight — heavy or light? Layers — can you see stripes?

🏠 Construction

Granite, limestone, and marble are used to build beautiful buildings and bridges.

🚗 Transportation

Crushed rocks make roads smooth and strong for cars and trucks to drive on.

💎 Decorations

Gems and stones are used to make jewelry that sparkles and shines beautifully.

Rocks are also used to make glass, cement, and even the sand in our sandboxes! Artists carve rocks to make sculptures and statues. Ancient people used rocks to make tools and build shelters. Without rocks, we wouldn't have many of the things we use every day. Rocks are truly one of Earth's greatest treasures!

Light

Understand how light helps us see

Light Sources

Light comes from different sources! Some light comes from nature, like the sun and stars. Other light is made by people, like lightbulbs and lamps. Let's explore natural and artificial light sources!

Natural vs Artificial Light NATURAL LIGHT ☀️ The Sun — our biggest light ⭐ Stars — shine in the night sky 🔥 Fire — flames give light & heat ⚡ Lightning — bright flashes 🐛 Glow-worms — living lights! ARTIFICIAL LIGHT 💡 Light bulbs — in our homes 🔦 Torch — portable light 🕯️ Candles — flame-based light 📺 Screens — TVs and phones 🚦 Traffic lights — keep us safe 🏮 Neon signs — colourful glow

Natural Light

Sun: Gives us light and heat during the day

Stars: Shine bright in the night sky

Fire: Creates light and warmth

Moon: Reflects sunlight at night

Artificial Light

Lightbulbs: Electric lights in our homes

Flashlights: Portable light we can carry

Street lamps: Light up roads at night

Candles: Flames that make light

Light Travel! Light travels super fast—the fastest thing in the universe! Sunlight takes 8 minutes to reach Earth. Light from other stars takes years and years to reach us!

Light Travels in Straight Lines! Light moves in straight lines called light rays. You can see this when sunlight shines through a gap in the curtains — the beam goes perfectly straight! Because light travels in straight lines, it cannot bend around objects. That is why shadows have sharp edges — the light goes straight past the object and leaves a dark shape behind it.

Shadows: Light's Dark Friends

A shadow is a dark area made when something blocks light. Shadows are everywhere! They appear on sunny days, under light bulbs, and even under moonlight. Shadows can be big, small, long, or short. The size and shape of shadows tell us something special about where the light is coming from!

How Shadows Form Light Source ☀️ Object 🌳 Shadow (dark area) Light cannot pass through the tree, so a dark shadow forms behind it

How Shadows Form

Shadows happen when light hits an object and can't pass through it. The light bounces off or stops at the object, creating a dark area behind it called a shadow. The shape of the shadow matches the shape of the object that's blocking the light! If you stand between a lamp and a wall, your shadow will appear on the wall.

⏰ Shadows Change: On sunny days, watch how your shadow gets longer in the morning, shorter at noon when the Sun is high, and long again in the afternoon. This happens because the Sun moves across the sky!

Types of Shadows

Shadows can be different in many ways. A sharp shadow has clear, dark edges. A fuzzy shadow has soft, blurry edges. A shadow can be shorter than the object or much longer. A shadow can even be upside-down! The position of the light source changes how the shadow looks. Try making hand shadows on a wall with a flashlight – you can make them look like animals!

🌞 Daytime Shadow

When the Sun is high in the sky, shadows are short and dark. When the Sun is near the horizon, shadows are long and thin.

💡 Lamp Shadow

Shadows made by lamps are darker and have sharper edges than sunny shadows.

✋ Hand Shadows

Your hands can make fun animal shadows on a wall. Try making a dog, rabbit, or bird!

Reflection: Bouncing Light

Reflection happens when light bounces off a smooth, shiny surface. Mirrors are perfect for reflecting light because they're so smooth and shiny. When you look in a mirror, you see your reflection – that's light bouncing off the mirror, hitting your eyes, and showing you your image!

How Reflection Works Mirror Incoming light hits the mirror Reflected light bounces back! same angle! The Rule of Reflection Light bounces off at the same angle it arrives — every time!

The Law of Reflection

Light always bounces off mirrors at the same angle that it hits them. If light comes in at a small angle, it bounces off at a small angle. If it comes in at a steep angle, it bounces off at a steep angle. This is called the Law of Reflection, and it never changes! This is why mirrors show us clear images of ourselves.

🪞 Mirror Magic: When you look at yourself in a mirror, you're not really seeing yourself directly. You're seeing light that bounced off your body, hit the mirror, bounced again, and came back to your eyes!

Reflective Surfaces

Not everything reflects light the same way. Mirrors reflect almost perfectly. Water reflects like a mirror when it's calm and smooth. Shiny metal, glass, and polished surfaces reflect light well. Rough surfaces like paper, cloth, and dirt scatter light in many directions instead of reflecting it clearly. This is why you can't see yourself in a piece of paper, but you can in aluminum foil!

🪞 Perfect Mirror

Very smooth and shiny. Reflects light clearly. You see a perfect image.

💧 Still Water

Acts like a mirror when calm. Creates beautiful reflections of the sky and objects.

📄 Paper

Rough surface scatters light. You can't see a reflection because light goes in all directions.

Transparent, Translucent & Opaque

Different materials let light through in different ways. Some materials you can see right through – we call them transparent. Others let some light through but blur the view – we call them translucent. Still others block light completely – we call them opaque. Let's explore how materials interact with light!

How Light Passes Through Materials Transparent All light passes ✓ 🪟 Clear glass 💧 Clean water 🌬️ Air You CAN see through Translucent Some light passes ~ 🥛 Frosted glass 📄 Wax paper 🌫️ Fog Blurry — can't see clearly Opaque No light passes ✗ 🧱 Brick wall 🪵 Wood ✋ Your hand Can't see through at all

🪟 Transparent

Let almost all light through. You can see clearly through them. Examples: glass, clear plastic, air.

🥛 Translucent

Let some light through but blur what you see. Examples: frosted glass, wax paper, fog.

🪵 Opaque

Block light completely. You can't see through them. Examples: wood, metal, brick, your hand.

💡 Light Path: Light travels in straight lines called light rays. It only changes direction when it hits something, bounces off something, or goes through something transparent. This is why we see shadows – light can't bend around objects!

Using These Properties

We use transparent, translucent, and opaque materials every day! Windows are transparent so we can see outside. Lampshades are translucent to spread light softly. Curtains are opaque to block light and give us privacy. Understanding how light moves through materials helps us design better things and solve problems in creative ways!

Rainbow Light

White light from the Sun is actually a mixture of many colors! When white light hits raindrops or passes through a prism (a special piece of glass), it splits into all the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. This amazing splitting of light is called refraction!

Splitting White Light with a Prism White light Prism Red Orange Yellow Green Blue Indigo Violet Remember the colours: ROY G. BIV Red, Orange, Yellow, Green, Blue, Indigo, Violet

How Rainbows Form

Rainbows appear when sunshine and rain happen at the same time! Sunlight enters raindrops and bounces around inside them. As light bounces, it bends and separates into colors. Each color bends at a slightly different angle, so red light comes out at one angle and violet light comes out at another angle. This creates the beautiful arc of colors we see in the sky!

🌈 Rainbow Facts: You always see a rainbow at your back when it's in front of you. The Sun must be behind you for you to see a rainbow. That's why rainbows appear in the morning or late afternoon, not in the middle of the day!

Colors of Light

Red is the color that bends the least, so it appears on the outside of a rainbow. Violet bends the most, so it appears on the inside. All the other colors line up between them in order: orange, yellow, green, blue, and indigo. Each color has a different wavelength – red has the longest waves and violet has the shortest waves. Together, all these colors make beautiful white light from the Sun!

🔴 Warm Colors

Red, orange, and yellow light. These colors feel warm and bright, like fire and sunshine.

🔵 Cool Colors

Blue, indigo, and violet light. These colors feel cool and calm, like water and twilight.

🌈 All Together

All seven colors of the rainbow mixed together make white light again!

Forces & Magnets

Explore pushes, pulls, and magnetic power

Pushes and Pulls

A force is a push or a pull that makes something move or changes how it moves. When you kick a ball, you're pushing it. When you pull a door open, you're pulling it. Forces are all around us!

Push and Pull Forces PUSH PULL

Everyday Forces

Pushes: Kick a ball, push a swing, shove a box

Pulls: Pull a door open, tug a rope, drag a sled

Both: Throw a ball (push), catch a ball (pull)

Forces Change Motion! A force can make something start moving, stop moving, go faster, go slower, or change direction. The stronger the push or pull, the more the object moves!

Friction: The Force That Stops Things

Friction is a special force that happens when two things rub against each other. Friction slows things down or stops them from moving. When you slide on ice, there's not much friction, so you slide a long way. When you slide on a rough carpet, there's lots of friction, so you stop quickly. Friction is super useful, but sometimes we want to reduce it!

Friction on Different Surfaces ICE Low Smooth GRASS Medium Medium SANDPAPER High Rough

When Friction Helps

Without friction, we couldn't walk! Friction between your shoes and the ground keeps you from slipping. Friction between a car's tires and the road lets the car grip the road. Friction between your hand and a pencil lets you hold it without dropping it. Friction helps us grip, control, and stay safe!

When Friction Gets In the Way

Sometimes friction causes problems. It makes objects heat up and wear out. When you rub two sticks together, friction creates heat. When a car's tires rub on the road, friction wears them down. To reduce friction, we use smooth materials, add oils and lubricants, and make things sleeker. Ice skates work because ice is so smooth that friction is very low, letting skaters glide easily!

✓ Good Friction

Walking, writing, gripping, stopping. We need friction for safety and control.

✗ Bad Friction

Wear and tear, heat, wasted energy. Less friction means smoother, faster movement.

⚙️ Reducing Friction

Use smooth surfaces, add lubricants (oil), or use ball bearings in machines.

🌡️ Heat from Friction: Rub your hands together quickly. Do you feel them getting warm? That heat comes from friction! The faster you rub and the rougher the surfaces, the more heat friction creates.

Magnets: Invisible Pulling Power

Magnets are special objects that can push or pull without touching! A magnet creates an invisible force field around it. Some objects like iron and steel are attracted to magnets. Other objects like plastic and wood don't get pulled toward magnets. Magnets are amazing and very useful in our daily lives!

Magnetic vs Non-Magnetic ATTRACTED NOT ATTRACTED N S Paperclip Nail Iron key N S Plastic cup Wood block Rubber ball

How Magnets Work

Inside every magnet, tiny atoms are lined up in the same direction. This makes the magnet have a North Pole and a South Pole. The magnetic force comes from these poles and creates an invisible field around the magnet. This field is strongest near the poles and gets weaker farther away. That's why a magnet can pull iron from a distance without touching it!

🧲 Magnetic Materials: Iron, steel, nickel, and cobalt are magnetic. They get pulled toward magnets. Most other materials like plastic, rubber, wood, and aluminum are not magnetic and don't get attracted to magnets.

Uses of Magnets

Magnets are everywhere! Doctors use magnets in MRI machines to see inside people's bodies. Refrigerators have magnetic seals. Compasses use magnets to point North. Electric motors use magnets to create movement. Speakers use magnets to make sound. Cranes use giant electromagnets to lift heavy metal objects. Magnets even hold information on computer hard drives! Without magnets, our modern world wouldn't exist.

🧲 Bar Magnet

A simple rectangular magnet with two poles. Great for experiments and moving small metal objects.

⭕ Horseshoe Magnet

Shaped like a horseshoe. Its poles face each other, making it very strong and good for picking things up.

⚡ Electromagnet

Made with electricity and a coil of wire. Can be turned on and off. Powers motors and lifting machines.

Magnetic Force The special force that magnets use is called magnetic force. Unlike a push or a pull from your hand, magnetic force can work without touching! A magnet can attract an iron paper clip from a distance — the magnetic force pulls the clip through the air towards the magnet. Magnetic force is strongest at the poles (ends) of a magnet.

Magnetic Poles and Attraction

Every magnet has two poles – a North Pole and a South Pole. Something amazing happens when you put two magnets near each other: opposite poles attract each other (pull toward each other), but same poles repel each other (push away from each other)! This push and pull between magnetic poles is one of the coolest things about magnets!

Magnetic Poles ATTRACTING (N-S) N S S N Magnets pull together REPELLING (N-N) N S N S Magnets push apart Key Facts: • Opposite poles attract: North + South pull toward each other • Same poles repel: North + North or South + South push apart
🧲 Pole Facts: You can never separate the two poles of a magnet! If you break a magnet in half, each piece becomes its own magnet with its own North and South poles. The poles always stay paired!

Understanding Magnetic Fields

A magnetic field is the invisible area around a magnet where its force works. You can't see the field, but you can see its effects! Sprinkle iron dust around a magnet, and you'll see patterns showing the invisible field lines. The field is strongest right at the poles and gets weaker far away. Two magnetic fields can interact – when they push, the magnets repel; when they line up opposite, they attract.

Compass Navigation

A compass is a magnet that spins freely. The Earth itself is a giant magnet with a North Pole and a South Pole! The compass needle aligns with Earth's magnetic field, always pointing toward the North Pole. This helps explorers, sailors, and hikers know which direction they're going. A compass needle is like a tiny magnet that talks to Earth's giant magnetic field!

Machines That Use Forces

Machines use forces to make our lives easier. Simple machines like levers, pulleys, ramps, and wheels use pushing and pulling forces to help us do work. Complex machines like cars, airplanes, and robots combine many forces to do amazing things. Let's explore how machines use forces to solve problems!

Compass N S W E NW NE SW SE The needle always points North! It follows Earth's magnetic field lines.

🔨 Lever

A bar that pivots on a point. Helps you lift heavy things by moving the lever down, pushing up the load.

🔄 Pulley

A wheel with a rope. Helps you lift things up by pulling the rope down. Changes direction of force.

📐 Ramp

A sloped surface. Makes it easier to move something heavy up because you don't have to lift as high.

All these simple machines change how forces work. A lever makes your push stronger. A pulley changes the direction of your pull. A ramp spreads the effort over a longer distance. Wheels reduce friction by rolling instead of sliding. When we combine these simple machines, we create complex machines that do incredible things – from bicycles that help us go fast to elevators that lift us high into the air!

Plants & Nutrition

Discover how plants grow and feed us

Parts of a Plant

Plants have special parts that help them grow and stay healthy. Each part does an important job! Let's learn about roots, stems, leaves, flowers, and fruits.

Parts of a Plant Roots Stem Leaves Flower Seeds

Plant Parts & Their Jobs

Roots: Soak up water and nutrients from the soil

Stem: Holds up the plant and carries water

Leaves: Make food using sunlight (photosynthesis!)

Flower: Makes seeds so new plants can grow

Fruit: Protects seeds and helps them spread

Plants Need Sun! Leaves are green because they contain a special color called chlorophyll. This green helps plants catch sunlight and turn it into food. That's why plants need sunlight to grow!

How Plants Drink Water

Plants need water to survive, just like we do! But plants don't drink like we do. Instead, their roots suck water from the soil. The water travels up through tiny tubes in the stem called the xylem. This water reaches the leaves, where it's used to make food and to cool the plant down. Amazing journey!

Water Transport in Plants Path of Water Through a Plant: Roots absorb water → Stem carries it up → Leaves use it (Blue arrows show the path)

The Water Journey

Water enters the plant through root hairs – tiny hairs on the roots that increase surface area. The water moves up the stem through tubes called the xylem. These tubes are like tiny straws carrying water all the way up to the leaves. Some water is used in photosynthesis to make food. Other water evaporates through tiny holes in the leaves called stomata, cooling the plant down. This process is called transpiration!

💧 Water Facts: A single large tree can release thousands of liters of water into the air through transpiration on a hot day! Plants are like living water fountains, helping to keep Earth's air moist and cool.

Why Water is Important

Water is essential for everything plants do. It helps plants stand up and keep their shape. It carries nutrients from the soil to all parts of the plant. It's needed for photosynthesis to make food. It helps cool the plant on hot days. Without water, plants would wilt and die. That's why plants in a desert have special features to save water – like thick, waxy leaves and deep roots that reach far down to find water!

Nutrients: Food From Soil

Plants don't just need water – they also need nutrients! Nutrients are special chemicals in the soil that plants need to grow big and strong. The main nutrients are nitrogen, phosphorus, and potassium. Plants suck these nutrients up through their roots, mixed with water. Without nutrients, plants get weak and sick, like when we don't eat healthy food!

What Plants Need to Grow Light Water Nutrients ≈ O≡C≡O CO₂

What Each Nutrient Does

🌿 Nitrogen

Helps leaves grow green and big. Plants use it to make proteins. Without it, leaves turn yellow and growth slows.

🌸 Phosphorus

Helps roots grow strong and helps plants make flowers and seeds. Important for energy in plant cells.

💪 Potassium

Helps plants resist disease and stress. Makes stems strong. Helps move water and nutrients around the plant.

🧑‍🌾 Fertilizer: Farmers add fertilizer to soil to give plants extra nutrients. Fertilizer is like a vitamin for plants! Good compost from dead plants and animals also provides nutrients naturally.

Nutrient Cycle

Plants get nutrients from soil. We eat plants for food. When plants and animals die and decompose, they return nutrients to the soil. Bacteria and fungi break down dead material into nutrients that plants can use again. This amazing cycle means nutrients keep moving from soil to plants to animals and back to soil, over and over again! Nothing is wasted in nature.

What is Photosynthesis? Photosynthesis is the amazing process where leaves use sunlight, water from the roots, and carbon dioxide from the air to make food (sugar) for the plant. The word "photosynthesis" means "making with light". During this process, plants also release oxygen — the gas we breathe! Without photosynthesis, there would be no food or oxygen on Earth.

Plants Make Their Own Food

Plants are amazing because they make their own food! This process is called photosynthesis. Plants use three ingredients: sunlight, water, and carbon dioxide from the air. They mix these together to make sugar – food that feeds the plant! We can eat the plants and get that energy too. That's why we need plants to survive!

Photosynthesis Sunlight Water CO₂ O₂ FOOD (Glucose) Sunlight + Water + CO₂ → Food + Oxygen

The Photosynthesis Formula

Photosynthesis happens in the leaves. Chlorophyll (the green stuff) catches sunlight energy. Water from the roots and carbon dioxide from the air combine to make glucose – a type of sugar that feeds the plant. As a bonus, photosynthesis releases oxygen that we breathe! Without photosynthesis, there would be no oxygen and we couldn't live. Thank you, plants!

🌱 Green Power: The green color in plants is chlorophyll. It's like tiny solar panels that capture sunlight energy! Plants with darker green leaves usually have more chlorophyll and make more food.

Plants as Food

We eat many plant parts. We eat fruits like apples and oranges. We eat vegetables like carrots, lettuce, and broccoli. We eat grains like rice, wheat, and corn. We even eat seeds like nuts and beans! All these foods give us energy and nutrients that the plant made. When we eat plants, we're getting the energy from the Sun that the plant captured! About 80% of human food comes directly from plants.

🥕 Vegetables

Plant parts like roots, stems, and leaves. Carrots are roots. Celery is stems. Lettuce is leaves.

🍎 Fruits

Grow from flowers and contain seeds. Apples, oranges, berries are all fruits! Even tomatoes are fruits!

🌾 Grains

Seeds from certain plants. Rice, wheat, corn, oats are grains. They have lots of energy stored in them.

Plant Life Cycle: From Seed to Plant

Plants grow through amazing stages. A tiny seed contains a baby plant and stored food. When conditions are right – with water, warmth, and oxygen – the seed wakes up and starts to grow! The cycle continues as the plant grows big, makes flowers, produces seeds, and starts the whole cycle again. It's like nature's magic trick!

Seed Germination Stages Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 ① Seed ② Root ③ Shoot ④ Leaves ⑤ Plant

Each Stage Explained

First comes the seed – a tiny package containing a baby plant and stored nutrients. When the seed gets water, warmth, and oxygen, it germinates (starts to grow). A root pops down and a shoot grows up. The seedling keeps growing, leaves get bigger, and the stem gets stronger. Eventually the plant is big and strong enough to make flowers. Flowers are pollinated by bees and butterflies. After pollination, seeds form inside fruits. The cycle begins again when seeds spread and find places to grow!

🌱 Seed Facts: Some seeds can wait for years before growing! They're waiting for the perfect conditions – the right amount of water, warmth, and light. When those conditions arrive, boom! The seed wakes up and starts growing.

Different Plant Types

Not all plants are the same. Some plants are very short grasses. Some are tall trees. Some plants are flowers that only last one season. Some plants are perennials that come back every year. Some plants have big seeds and some have tiny dust-like seeds. Some plants grow from bulbs underground. Desert plants have special features to save water. Rainforest plants climb and grow on other plants to reach the sunlight. Each plant is specially adapted to its home!

Grammar

Master nouns, verbs, adjectives, and adverbs

Nouns

A noun is a word that names a person, place, or thing. Nouns are everywhere! When you talk about things, places, and people, you're using nouns!

Types of Nouns NOUNS Person teacher girl doctor boy friend mother Place school park city home beach library Thing book ball table pencil chair apple

Common & Proper Nouns

Common nouns: Any person, place, or thing (lowercase)

boy, girl, dog, city, book, toy

Proper nouns: Specific person, place, or thing (start with capital)

Sarah, Tom, Paris, New York, Fluffy, Tuesday

Noun Hunt! Look around your classroom. Can you name 10 nouns? Try finding at least 3 persons, 3 places, and 4 things. Remember: people's names are proper nouns!

What Are Verbs?

A verb is an action word! It tells what someone or something is doing. Every sentence needs a verb to show action or state of being. Verbs are the words that make sentences come alive!

Action verbs show movement or doing something. They're easy to spot because you can see them happening. Other verbs, called linking verbs, connect the subject to a description.

Action Verbs

jump, run, sing, eat, write, laugh, dance, play, swim, read, build, draw

Action Verbs

Examples:

She runs fast.
Dogs bark.
I drew a picture.

Linking Verbs (is, am, are)

Examples:

I am happy.
The sky is blue.
We are friends.

Action Verbs Verbs are ACTION words! running jumping reading swimming

Try this: Look at a sentence and find the action! In "The boy throws the ball," what is the action? That's the verb: throws!

What Are Adjectives?

An adjective is a word that describes a noun. It tells you more information about a person, place, or thing. Adjectives help create a picture in the reader's mind by adding details.

Adjectives answer questions like: What kind? How many? What color? What size? What does it look like? Using adjectives makes your writing more interesting and vivid!

Common Adjectives

Color: red, blue, green, yellow, purple

Size: big, small, tall, short, long

Feeling: happy, sad, angry, tired, sleepy

Number: one, two, three, many, few

Without Adjectives

"The cat is on the mat."

Plain and simple.

With Adjectives

"The fluffy orange cat is on the soft red mat."

Much more interesting!

Adjectives Describe Nouns ball plain big red bouncy Adjectives add interesting details!

What Are Adverbs?

An adverb is a word that describes a verb! It tells you HOW, WHEN, or WHERE something happens. Adverbs often end in -ly and add more information to make sentences clearer and more interesting.

Adverbs help us understand the action better. They answer: How is it done? When did it happen? Where did it happen? Adverbs make stories more detailed and fun to read!

Types of Adverbs

How (Manner): quickly, slowly, happily, carefully, loudly

When (Time): today, yesterday, now, soon, later

Where (Place): here, there, outside, inside, below

Verb Without Adverb

She walked.

We know she walked, but how?

Verb With Adverb

She walked quickly.

Now we know HOW she walked!

More Examples:

Conjunctions: Joining Words

Conjunctions are words that join other words, phrases, or sentences together. They are like bridges that connect ideas! The most common conjunctions are: and, but, or, so, because.

Without Conjunctions

"I like cats. I like dogs."

"She was tired. She kept playing."

Two short, choppy sentences

With Conjunctions

"I like cats and dogs."

"She was tired but she kept playing."

Smooth and connected!

The Five Key Conjunctions

AND — adds ideas together: "I like apples and bananas."

BUT — shows a contrast: "I like cats but I'm allergic."

OR — gives a choice: "Do you want tea or juice?"

SO — shows a result: "It was raining so we stayed inside."

BECAUSE — gives a reason: "I'm happy because it's my birthday."

Try It! Join these sentences using a conjunction: "I wanted to go outside." + "It was raining." → "I wanted to go outside but it was raining."

Verb Tenses: Past, Present, Future

Verbs can tell us when something happens. We call this the tense. There are three main tenses: past (already happened), present (happening now), and future (will happen).

The Three Tenses

Past tense (yesterday): I walked to school. She played outside. He ran fast.

Present tense (today): I walk to school. She plays outside. He runs fast.

Future tense (tomorrow): I will walk to school. She will play outside. He will run fast.

Regular Verbs

Add -ed for past tense:

walk → walked

play → played

jump → jumped

talk → talked

Irregular Verbs

These change their form:

run → ran

go → went

see → saw

eat → ate

Subject-Verb Agreement: The verb must match the subject! "She goes" (not "she go"). "They go" (not "they goes"). "I am happy" (not "I is happy").

Comprehension

Understand and analyze stories and texts

Fiction Stories

Fiction stories are made up! They come from an author's imagination. Fiction stories can be about anything—dragons, space adventures, talking animals, or magical lands. They might feel real, but the author invented them!

Fiction

Made up! An author created these characters and events.

Examples: Fairy tales, fantasy adventures, made-up animal stories

"Cinderella" and "Charlotte's Web" are fiction!

Nonfiction

Real facts! True information about the world.

Examples: Biographies, science books, history books

"How Caterpillars Become Butterflies" is nonfiction!

Elements of Fiction

Characters: The people or animals in the story

Setting: When and where the story takes place

Plot: What happens in the story (the problem and how it's solved)

Problem: The challenge the character must face

Solution: How the character solves the problem

Create Your Own Fiction! Think of a character. Where do they live? What problem do they face? How do they solve it? You can be an author and make up your own amazing story! Authors use their imagination to create wonderful fiction that entertains and inspires readers.

Story Elements

Every story has important parts that work together to tell the whole story. These parts are called story elements. Understanding story elements helps you enjoy and remember stories better!

The Five Main Story Elements:

Character: The person or animal the story is about

Setting: Where and when the story takes place

Plot: What happens in the story - the beginning, middle, and end

Problem: The challenge or conflict the character faces

Solution: How the character solves the problem

Parts of a Nonfiction Text AMAZING ANIMALS Heading: Lions are big cats Paragraph: Image Caption: A lion resting in the sun Important words are BOLD to stand out Title Heading Paragraph Caption

Example: "The Little Red Hen"

Making Inferences

An inference is when you figure something out using clues from the story and what you already know. You're like a detective, looking for clues to understand what the story doesn't say directly!

Good readers make inferences all the time. You use picture clues, story clues, and your own experience to understand more about the characters and what's happening in the story.

How to Make an Inference

  1. Look for clues in the story
  2. Think about what you already know
  3. Combine the clue with your knowledge
  4. Figure out something new about the story

Story Clue

"Sarah put on her coat and took an umbrella."

The story doesn't say it's raining, but we can infer...

My Inference

"It must be cold and rainy outside."

We used clues to figure this out!

More Inference Examples:

Summarizing Stories

A summary is a short version of a story that tells only the most important ideas. When you summarize, you don't tell every detail - just the main points that are necessary to understand what happened.

Summarizing helps you remember stories better. It also helps you explain stories to other people in a quick and easy way. Good summaries are short, clear, and tell what the story is really about.

How to Write a Summary

  1. Read or listen to the whole story
  2. Think about the main character and problem
  3. Identify the most important events
  4. Write a few sentences about what happened
  5. Make sure your summary is much shorter than the original story

Example Summary:

Original Story (long):

Once there was a boy named Jack who lived with his mother. They were very poor. Jack's mother told him to sell their cow at the market. On the way, a man offered Jack magical beans for the cow. Jack agreed and brought the beans home, but his mother was angry and threw them out the window. The next morning, a giant beanstalk had grown. Jack climbed it and found a castle in the clouds. Inside the castle, he found gold and other treasures. He filled his pockets and climbed back down the beanstalk as fast as he could. The giant chased him, but Jack cut down the beanstalk and the giant fell. Jack and his mother became rich and lived happily ever after.

Summary (short):

Jack trades a cow for magical beans. A giant beanstalk grows, and Jack climbs it to a castle in the clouds. He steals treasures, cuts down the beanstalk, and becomes rich.

Place Value

Understand how numbers work

Hundreds, Tens, and Units

Every number is made up of parts. In the number 345, the 3 is in the hundreds place, the 4 is in the tens place, and the 5 is in the units (ones) place. Understanding place value helps us read, write, and work with numbers!

Place Value Chart: 345 Hundreds 3 3 × 100 = 300 Tens 4 4 × 10 = 40 Units (Ones) 5 5 × 1 = 5

Place Value Formula: Every digit's value depends on where it is in the number. A digit in the hundreds place is worth 100 times more than the same digit in the tens place!

The Digit 3

In 345: The 3 is worth 300

In 238: The 3 is worth 30

In 123: The 3 is worth 3

Breaking Down Numbers

237 =

2 hundreds + 3 tens + 7 ones

= 200 + 30 + 7

Reading & Writing Numbers to 1000

Now that you understand place value, you can read and write any number up to 1000! When you read a number, you say the value of each digit in its place.

How to Read Numbers

456: We read this as "four hundred and fifty-six"

200: We read this as "two hundred"

100: We read this as "one hundred"

89: We read this as "eighty-nine" (no hundreds)

Writing Numbers in Words

You can write numbers two ways: as digits (using numbers) or as words (spelled out).

Numbers 1-20

1 = One
5 = Five
10 = Ten
15 = Fifteen
20 = Twenty

Tens (20-100)

30 = Thirty
40 = Forty
60 = Sixty
80 = Eighty
100 = One Hundred

Hundreds

200 = Two Hundred
500 = Five Hundred
750 = Seven Hundred Fifty
999 = Nine Hundred Ninety-nine
1000 = One Thousand

Tip: When writing numbers with both tens and ones, put an 'and' or a hyphen between them. For example: "three hundred and twenty-seven" or "three hundred twenty-seven".

Comparing & Ordering Numbers

When you compare numbers, you look at which one is bigger or smaller. You use special symbols to show how numbers compare: > (greater than), < (less than), or = (equal to).

Comparing Numbers 345 > (greater than) 234 345 has 3 hundreds 234 has 2 hundreds 567 = 567 Same number! 198 < (less than) 201 198 has fewer tens than 201

Ordering Numbers from Smallest to Largest

To put numbers in order, start with the hundreds place. If the hundreds are the same, look at the tens. If the tens are the same, look at the ones.

Example: Put in order: 456, 234, 645

Look at hundreds: 2 hundreds, 4 hundreds, 6 hundreds

Order from smallest to largest: 234, 456, 645

Ordering Tip: Always start by looking at the biggest place value first (hundreds). Only if the hundreds are the same do you look at tens.

Rounding to Nearest 10 & 100

Rounding helps us work with simpler numbers. When we round, we change a number to the nearest 10 or 100. This is super useful for quick math!

Rounding to Nearest 10 20 30 40 50 60 37 Is 37 closer to 30 or 40? 37 rounds up to 40 Rounding Rule Look at the ONES digit If it's 0, 1, 2, 3, or 4: Round DOWN If it's 5, 6, 7, 8, or 9: Round UP

Rounding to Nearest 100

To round to the nearest 100, look at the TENS digit.

347 rounds to 300 (tens digit is 4, so round down)

368 rounds to 400 (tens digit is 6, so round up)

750 rounds to 800 (tens digit is 5, so round up)

Why Round? Rounding makes numbers easier to work with. Instead of adding 237 + 156, you can quickly add 200 + 200 = 400 for an estimate!

Fun Place Value Activities

Let's practice place value with exciting activities! These games help you master hundreds, tens, and ones.

Activity 1: Build the Number

Challenge: Can you make 567 using:

5 hundreds blocks + 6 tens blocks + 7 ones blocks

That's exactly 500 + 60 + 7 = 567!

Activity 2: Number Detective

I'm thinking of a number:

• It has 3 in the hundreds place

• It has 8 in the tens place

• It has 2 in the ones place

What number am I? Answer: 382!

Expanded Form Examples 245 = 200 + 40 + 5 2 hundreds + 4 tens + 5 ones 608 = 600 + 0 + 8 6 hundreds + 0 tens + 8 ones 931 = 900 + 30 + 1

Real-Life Math: When you count money, you use place value! A dollar bill = 100 cents, a dime = 10 cents. So 3 dollars, 2 dimes, and 5 cents = $3.25!

Addition & Subtraction

Master the fundamentals of math

Mental Methods

Mental math means solving problems in your head without writing anything down! There are special tricks you can use to add and subtract quickly. Let's learn them!

Trick 1: Count On

Problem: 7 + 5 = ?

Start at 7. Then count on: 8, 9, 10, 11, 12

You counted 5 numbers, so the answer is 12

Trick 2: Make 10

Problem: 8 + 7 = ?

8 + 2 = 10 (take 2 from the 7)

10 + 5 = 15 (the 5 is left from 7)

Answer: 15

Make 10 Strategy 6 + 7 6 circles 7 circles = 13 8 + 9 Take 2 from 9 8 + 2 = 10 Then add the 7 left 10 + 7 = 17 Answer = 17

Mental Subtraction: Count back to subtract! For 12 - 5, start at 12 and count back: 11, 10, 9, 8, 7. You're at 7!

Column Addition

Column addition is when you line numbers up by their place value (ones under ones, tens under tens). Then you add each column starting from the right!

Column Addition: 234 + 125 Step 1: Line up 234 +125 Step 2: Add ones 234 +125 4 + 5 = 9 Step 3: Add tens 234 +125 3 + 2 = 5 tens Step 4: Add hundreds 234 +125 359

Without Carrying

When the sum of a column is less than 10, you just write it down. Easy!

With Carrying

Sometimes a column adds up to 10 or more. Then you need to "carry" the tens to the next column.

Example: 27 + 15

Ones: 7 + 5 = 12 (write 2, carry 1 ten)

Tens: 2 + 1 + 1 carried = 4

Answer: 42

Carrying Tip: When your ones add up to 10 or more, you're making a new ten! Always carry it to the tens column.

Column Subtraction

Column subtraction is similar to addition - you line up the numbers and subtract each column from right to left. Start with the ones!

Simple Subtraction: 356 - 123

Ones: 6 - 3 = 3

Tens: 5 - 2 = 3

Hundreds: 3 - 1 = 2

Answer: 233

Subtraction with Borrowing

Sometimes the top digit is smaller than the bottom digit. You need to "borrow" from the next column!

Subtraction with Borrowing: 42 - 15 Problem 42 -15 Can't take 5 from 2! Borrow 1 ten Now 2 becomes 12 Now subtract 12 - 5 = 7 3 - 1 = 2 Answer: 27

Borrowing Tip: When you borrow a ten from the tens place, it becomes 10 ones. So if you had 4 tens and 2 ones, borrowing gives you 3 tens and 12 ones!

Word Problems

Word problems tell a story with numbers. You have to read carefully, understand what the problem is asking, and then solve it!

Example Problem 1

Story: Sarah has 23 stickers. Her friend gives her 15 more stickers. How many stickers does Sarah have now?

What to do: This is adding! 23 + 15 = 38

Answer: Sarah has 38 stickers.

Example Problem 2

Story: Tom had 45 apples. He gave 18 apples to his neighbor. How many apples does Tom have left?

What to do: This is subtraction! 45 - 18 = 27

Answer: Tom has 27 apples left.

How to Solve Word Problems

Step 1: Read Carefully

Understand what the story is about. Look for clue words like "altogether," "more," "left," or "how many."

Step 2: Identify the Operation

Is it adding (putting together) or subtracting (taking away)?

Step 3: Write the Number Sentence

Write the problem like: 23 + 15 = ?

Step 4: Solve & Check

Do the math. Read the answer back to the problem to make sure it makes sense!

Clue Words: "More," "altogether," "total," "added," "in all" = ADD | "Less," "left," "gave away," "removed" = SUBTRACT

Number Sentences: A number sentence is a maths statement using numbers and symbols. For example: 4 + 4 = 8 is a true number sentence. But 5 + 3 = 9 is false (because 5 + 3 = 8, not 9).
You can check if a number sentence is true by working out the left side and seeing if it equals the right side. Number sentences use +, −, ×, ÷, and =.

Measurement

Learn to measure length, mass, capacity, and time

Length: mm, cm, and m

Length tells us how long or tall something is. We measure length using millimetres (mm), centimetres (cm), and metres (m). Each one is used for different things!

Measuring Length 0 1 cm 2 cm 3 cm 4 cm 5 cm This pencil is 2 cm Conversion Guide 1 centimetre = 10 millimetres (10 mm) 1 metre = 100 centimetres (100 cm) 1 metre = 1000 millimetres (1000 mm)

Millimetres (mm)

Very small! Use for tiny things like insects, pencil tips, or seeds.

Centimetres (cm)

Medium size! Use for pencils, paper, hands, or small toys.

Metres (m)

Large! Use for rooms, playgrounds, or distances between places.

Measuring Tip: Always start your ruler at 0. Place the object along the ruler and read where the other end lands!

Mass: g and kg

Mass tells us how heavy something is. We measure it in grams (g) and kilograms (kg). Heavier things have more mass!

Measuring Mass on a Scale 50g 250g Grams (g) Use for light things like apples (100g), chocolate bars (50g), or feathers (5g) 1000g = 1 kg Kilograms (kg) Use for heavier things like a bag of sugar (1 kg), you (25-30 kg), or a bicycle (15 kg)

Real-Life Examples

A pencil weighs about 5 grams. A tennis ball weighs about 60 grams. Your dog might weigh 20 kilograms. A small car weighs about 1000 kilograms!

Weight vs. Mass: In everyday life, we use "weight" and "mass" the same way. But scientists know they're different. We'll just call it "how heavy something is!"

Capacity: ml and L

Capacity tells us how much liquid something can hold. We measure it in millilitres (ml) and litres (L). Bigger containers have more capacity!

Containers and Capacity 5 ml 200 ml 500 ml 1 L 1 Litre Capacity Conversions 1 litre = 1000 millilitres (1000 ml) 10 ml = 2 teaspoons | 5 ml = 1 teaspoon 200 ml = roughly 1 cup | 1000 ml = 1 full bottle

Everyday Capacity Examples

A spoon holds about 5 ml. A glass holds about 250 ml. A juice bottle holds about 1 litre (1000 ml). A bath holds about 100-150 litres!

Tip: When cooking or mixing drinks, capacity matters! Always measure carefully to get the right amount.

Telling Time

Time helps us know when things happen. We measure time in seconds, minutes, hours, days, weeks, months, and years!

Analog Clock 12 3 6 9 Hour hand (short) Minute hand (long) 60 seconds = 1 minute | 60 minutes = 1 hour | 24 hours = 1 day | 7 days = 1 week

Reading an Analog Clock

The Minute Hand (long)

Shows the minutes. Each number is 5 minutes.

12 = 0 minutes | 3 = 15 minutes | 6 = 30 minutes

The Hour Hand (short)

Shows the hour (the bigger time).

When it points at 2, the hour is 2 o'clock (or between 1-3 o'clock)

Reading Times

When the hour hand points at 2 and the minute hand points at 3, the time is 2:15 (two fifteen, or quarter past two).

When both hands point at 12, the time is 12:00 (midnight or noon).

Digital vs. Analog: Digital clocks show time as numbers (3:15). Analog clocks have hands. Both tell the same time!

Imperial Units (for US students): In the United States, length is often measured in inches and feet instead of centimetres and metres.
1 foot = 12 inches (1 ft = 12 in)
1 yard = 3 feet (1 yd = 3 ft)
1 inch is about 2.5 centimetres. 1 foot is about 30 centimetres. 1 metre is a little longer than 1 yard.
A pencil is about 7 inches long. A door is about 7 feet tall. A football pitch is about 100 yards.

Measurement Adventures

Time to practice measurement with fun activities! Get a ruler, scale, or measuring cup and try these!

Activity 1: Measure Me!

Use a ruler or measuring tape to find:

• How tall you are (in cm or m)

• The length of your hand (in cm)

• The width of your desk (in cm)

Write down all your measurements!

Activity 2: Weigh Objects

Using a scale, find the mass of:

• Your backpack

• A book

• A toy

Which is heaviest? Which is lightest?

Activity 3: Fill It Up

Use a measuring cup to see how much liquid different containers hold:

• A small cup

• A bowl

• A mug

Measurement in Real Life: Builders use measurements to make houses. Doctors measure how tall and heavy you are. Scientists measure everything! Measurement is super important.

Money

Learn about coins, notes, and making change

UK Coins & Notes

In the United Kingdom, we use pounds (£) and pence (p) to buy things. There are 100 pence in 1 pound. Let's learn about all the coins and notes!

UK Coins

There are 8 coins used in the UK:

1p — One penny. The smallest value coin. Copper coloured.

2p — Two pence. Also copper coloured, but bigger than 1p.

5p — Five pence. Small and silver coloured.

10p — Ten pence. Larger silver coin.

20p — Twenty pence. A 7-sided silver coin!

50p — Fifty pence. Also 7-sided, bigger than 20p.

£1 — One pound (= 100p). Gold coloured with 12 sides.

£2 — Two pounds. The biggest coin, gold and silver coloured.

UK Notes

£5 — Five pounds. Blue coloured.

£10 — Ten pounds. Brown/orange coloured.

£20 — Twenty pounds. Purple coloured.

£50 — Fifty pounds. Red coloured.

Key Fact: 100p = £1. So £1.50 means 1 pound and 50 pence. You can write it as £1.50 or as 150p — they mean the same thing!

Making Amounts with UK Coins

You can make the same amount in different ways:

50p = one 50p coin, OR two 20p + one 10p, OR five 10p coins

£1 = one £1 coin, OR two 50p, OR five 20p, OR ten 10p

£1.50 = one £1 + one 50p, OR three 50p coins

US Coins & Bills

In the United States, money uses dollars ($) and cents (¢). There are 100 cents in 1 dollar. Let's learn about the coins!

US Coins

Penny — Worth 1¢ (one cent). It's copper coloured and has Abraham Lincoln on it.

Nickel — Worth 5¢ (five cents). Bigger than a penny, silver coloured. It takes 5 pennies to make a nickel!

Dime — Worth 10¢ (ten cents). The smallest US coin, but worth more than a nickel!

Quarter — Worth 25¢ (twenty-five cents). The most commonly used coin. 4 quarters = $1.00.

Remember: 100¢ = $1.00. A dollar has 100 cents, just like a pound has 100 pence!

Coin Values to Remember

5 pennies = 1 nickel (5¢)

2 nickels = 1 dime (10¢)

5 nickels = 1 quarter (25¢)

4 quarters = 1 dollar ($1.00)

10 dimes = 1 dollar ($1.00)

20 nickels = 1 dollar ($1.00)

US Bills (Notes)

$1 — One dollar bill. Has George Washington.

$5 — Five dollar bill. Has Abraham Lincoln.

$10 — Ten dollar bill. Has Alexander Hamilton.

$20 — Twenty dollar bill. Has Andrew Jackson.

Counting Money

To count a collection of coins, start with the biggest value coins and work down to the smallest. This makes counting easier!

Steps to Count Coins

Step 1: Sort your coins by value (biggest first).

Step 2: Count the biggest coins first, keeping a running total.

Step 3: Add on the smaller coins one at a time.

Step 4: Write your total using £ or $ and p or ¢.

Example: Count these UK coins

You have: 50p, 20p, 10p, 5p, 2p

Count: 50p → 70p → 80p → 85p → 87p

Total = 87p

Example: Count these US coins

You have: 1 quarter, 1 dime, 2 nickels, 3 pennies

Count: 25¢ → 35¢ → 40¢ → 45¢ → 46¢ → 47¢ → 48¢

Total = 48¢

Top Tip: When adding coins, count in jumps: quarters jump by 25, dimes by 10, nickels by 5. In UK money, count 50p, 20p, 10p coins first for the same reason!

Making Change

When you buy something and pay more than the price, you get change back. Change is the difference between what you paid and what the item costs.

How to Work Out Change

Method 1 — Subtract: Change = Amount paid − Price

Example: You have £1.00 and buy a sweet for 60p.

Change = 100p − 60p = 40p

Method 2 — Count Up

Start at the price and count up to the amount paid.

Example: Item costs 80p, you pay with £1.50

80p → 90p (add 10p) → £1.00 (add 10p) → £1.50 (add 50p)

Change = 10p + 10p + 50p = 70p

UK Example

You have £1.50 and spend 80p on a drink.

£1.50 = 150p, spend 80p

150p − 80p = 70p change

US Example

A pencil costs 10¢. You buy 5 pencils.

5 × 10¢ = 50¢. If you pay with $1.00:

100¢ − 50¢ = 50¢ change

Real-World Skill: Making change is one of the most useful maths skills you'll ever learn! Every time you go to a shop, you use subtraction to check your change.

Money Word Problems

Money word problems ask you to add, subtract, multiply, or compare prices. Look for clue words to work out which operation to use!

Addition Problems

Q: You buy a toy for £2.50 and a book for £1.20. How much altogether?

A: £2.50 + £1.20 = £3.70

Clue words: "altogether," "total," "how much in all"

Subtraction (Change) Problems

Q: You have £5.00 and buy a snack for £1.75. How much left?

A: £5.00 − £1.75 = £3.25

Clue words: "how much left," "change," "difference"

Multiplication Problems

Q: A pencil costs 10¢. How much do 5 pencils cost?

A: 5 × 10¢ = 50¢

Clue words: "each," "per item," "how much for 5"

Comparing Problems

Q: A toy costs £3.50 and a game costs £5.00. How much more is the game?

A: £5.00 − £3.50 = £1.50 more

Clue words: "how much more," "how much less," "cheaper," "dearer"

Remember: Always check your units! Don't mix pounds and pence without converting. £1.50 = 150p. $1.00 = 100¢.

Fun Money Activities

Money is one of the most practical things you'll learn in maths! Here are some fun ways to practise.

Activity 1: Shop Role-Play

Set up a pretend shop at home! Put price tags on toys and household items. Take turns being the shopkeeper and customer. The shopkeeper must give the right change!

Activity 2: Coin Sort

Empty a jar of coins and sort them by value. Count each pile, then add up the grand total. How much money is in the jar?

Activity 3: Budget Challenge

Imagine you have £5.00 (or $5.00) to spend at a pretend shop. Plan what you would buy and work out your total and change. Can you buy everything on your list?

Did You Know?

The word "salary" comes from the Latin word "sal" meaning salt. In ancient Rome, soldiers were sometimes paid in salt because it was so valuable! The word "money" comes from the Roman goddess Juno Moneta, whose temple was used as a mint to make coins.

Animals Including Humans

Discover how our bodies work

Nutrition & Food Groups

Food gives our bodies energy and helps us grow strong. Different foods do different jobs! Let's learn about the five food groups and how they help us.

Food Groups Plate Vegetables Fruits Grains Proteins Dairy

Vegetables

Give us vitamins and minerals. Examples: carrots, broccoli, spinach, peas, potatoes.

Fruits

Give us vitamin C and energy. Examples: apples, bananas, oranges, berries, grapes.

Grains

Give us energy to run and play. Examples: bread, rice, pasta, cereal, oats.

Proteins

Help us grow strong and build muscles. Examples: chicken, fish, eggs, beans, nuts.

Dairy

Make our bones and teeth strong. Examples: milk, cheese, yogurt, butter.

Eating Healthy

To be healthy, you should eat foods from all five groups every day. Eat more fruits and vegetables, less sugary treats. Drink water instead of soda. Eat the right amount - not too much!

Healthy Eating Rule: Fill half your plate with fruits and vegetables. A quarter with grains. A quarter with proteins. And add dairy on the side!

The Skeleton

Your skeleton is the framework of your body! It's made of 206 bones that are connected together. Bones give your body shape, protect your organs, and help you move.

Your Skeleton Skull Spine Ribs Pelvis Arm Leg

What Do Bones Do?

Give Shape

Bones hold your body up and give it shape so you look like you do!

Protect

Your skull protects your brain. Your ribs protect your heart and lungs.

Help You Move

Muscles pull on bones to make them move. That's how you run, jump, and play!

Fun Bone Facts

Your bones are living! They grow with you. Babies have about 270 bones, but some join together as you grow.

The longest bone in your body is the femur (thigh bone). The tiniest bones are in your ear!

Keep Your Bones Strong: Eat foods with calcium (milk, cheese, yogurt). Exercise and play outside. Get sunlight so your body makes vitamin D!

Muscles & Movement

Muscles are groups of special cells that can squeeze and relax. When muscles squeeze, they pull on your bones and make you move! You have more than 600 muscles!

How Muscles Work Relaxed Muscle Muscle is loose Bone can't move much Contracted Muscle Muscle squeezes Bone moves! Major Muscles We Use Every Day Biceps: Help bend your arm Quadriceps: On the front of your leg, help you run and jump Hamstrings: On the back of your leg, help you bend your knee Pectorals: In your chest, help you throw and push Abdominals: In your stomach, help you bend and twist

Keep Your Muscles Strong: Exercise! Run, play sports, swim, dance, or do yoga. Strong muscles help you do amazing things!

Staying Healthy

Your body is amazing, and it needs good care! Healthy choices help you feel great, grow strong, and have energy to play and learn.

Habits for a Healthy Body

  • Eat healthy foods: Lots of fruits, vegetables, whole grains, proteins, and dairy
  • Drink water: At least 6-8 glasses every day
  • Exercise: Move your body 60 minutes every day - play, sports, dancing, walking
  • Sleep: Get 8-10 hours every night so your body can rest and grow
  • Wash hands: Before eating and after playing to stay germ-free
  • Brush teeth: Morning and night to keep them strong and cavity-free
  • Have fun: Play, laugh, and be with friends - happiness is healthy!
Daily Health Checklist Morning Routine □ Brush teeth □ Eat a healthy breakfast □ Drink water □ Get moving! (walk or play) □ Wash hands before school Before Bedtime □ Eat a healthy dinner □ Play outside or exercise □ Wash hands and face □ Brush teeth □ Get 8-10 hours sleep

Remember: Your body is special and unique. Be kind to it! Eat good food, move, play, and get rest. That's the secret to feeling amazing!

Classifying Living Things

All the things around us can be sorted into two groups: living things and non-living things. But how do we know if something is alive? Scientists use seven life processes — you can remember them with MRS GREN!

MRS GREN — The 7 Life Processes

Movement — Living things can move (animals walk, plants turn to face the sun)

Respiration — Living things use energy by breathing

Sensitivity — Living things sense and respond to their surroundings

Growth — Living things grow bigger and change over time

Reproduction — Living things make babies or new copies of themselves

Excretion — Living things get rid of waste

Nutrition — Living things need food and water

Plants vs Animals

Plants

Make their own food using sunlight (photosynthesis)

Have roots, stems, and leaves

Cannot move from place to place

Examples: trees, flowers, grass, ferns

Animals

Eat plants or other animals for food

Have senses (eyes, ears, nose, mouth)

Can move around freely

Examples: humans, insects, fish, birds

Vertebrates & Invertebrates

Animals can be split into two big groups:

Vertebrates (have a backbone)

Mammals: Warm-blooded, have fur/hair, feed babies milk (dogs, cats, humans, whales)

Birds: Have feathers and wings, lay eggs (robins, eagles, penguins)

Reptiles: Cold-blooded, scaly skin, lay eggs (snakes, lizards, turtles)

Fish: Live in water, breathe with gills, have scales (salmon, sharks, goldfish)

Amphibians: Live on land and water, moist skin (frogs, toads, newts)

Invertebrates (no backbone)

Insects: 6 legs, 3 body parts (ants, bees, butterflies)

Arachnids: 8 legs (spiders, scorpions)

Molluscs: Soft bodies, often with shells (snails, slugs, octopus)

Worms: Long, soft bodies (earthworms)

Crustaceans: Hard shells, many legs (crabs, lobsters)

Did you know? About 97% of all animals on Earth are invertebrates! Insects alone make up more than half of all known animal species. There are more species of beetle than any other type of animal!

Body Adventures

Let's explore your body with these fun activities! You'll discover how much your amazing body can do.

Activity 1: Feel Your Bones

Press gently on different parts of your body and feel the bones underneath:

• Your skull (under your skin on top of your head)

States of Matter

Discover solids, liquids, and gases

Solids, Liquids & Gases

Everything around us is made of matter. Matter comes in three main states: solids, liquids, and gases. Let's explore what makes each one special!

🧱

Solid

Fixed shape and size. Doesn't change shape easily.

Examples: ice, wood, rock

💧

Liquid

Flows and takes the shape of its container.

Examples: water, milk, juice

☁️

Gas

Fills any space it's in. Can't be held in your hand.

Examples: air, steam, oxygen

💡 Did You Know?

The same material can be all three states! Water is a solid (ice), a liquid (water), and a gas (steam). Cool, right?

Changing States

Matter can change from one state to another. Here are the ways it happens:

Melting

Solid → Liquid

Heat turns a solid into a liquid. Example: ice cream melting on a warm day! 🍦

Freezing

Liquid → Solid

Cold turns a liquid into a solid. Example: water freezing into ice cubes. 🧊

Evaporation

Liquid → Gas

Heat turns a liquid into a gas. Example: puddles disappearing on a sunny day! ☀️

Condensation

Gas → Liquid

Cold turns a gas into a liquid. Example: water droplets on a steamy bathroom mirror! 🪞

Ice Melting Water Evaporation Steam Condensation

Floating & Sinking

Why do some things float and others sink? It's all about how heavy something is for its size—called density!

🪵

Floats!

Light for its size. Less dense than water.

Examples: wood, boats, cork

🪨

Sinks!

Heavy for its size. More dense than water.

Examples: stone, metal, sand

🧪 Try This!

Put different objects in water: a pencil, a toy, a leaf, a coin. Which float and which sink? Why do you think that happens?

Materials Around Us

Different materials have different properties. We choose materials based on what we need!

🪵 Wood

Hard, strong, can bend slightly, floats

🔩 Metal

Hard, very strong, shiny, conducts heat

🧊 Glass

Hard, transparent, breaks easily, smooth

🎒 Plastic

Light, flexible, waterproof, durable

🧵 Fabric

Soft, flexible, absorbs water, warm

🧱 Rubber

Bouncy, flexible, waterproof, stretchy

Why Choose Different Materials?

  • A spoon needs to be hard and heat-safe (metal or plastic) ✓
  • A blanket needs to be soft and warm (fabric) ✓
  • A cup needs to be hard and waterproof (ceramic, glass, or plastic) ✓
  • A ball needs to be bouncy and light (rubber or plastic) ✓

Fun Activities

🧪 Melting Race

Habitats & Food Chains

Where animals live and what they eat

What is a Habitat?

A habitat is a place where an animal lives. It has everything the animal needs: food, water, shelter, and space. Different animals live in different habitats!

Forest 🦌 🐻 🐦 Ocean 🐠 🐳 🐙 Desert 🦎 🐪 🦅 Arctic 🐧 🐻‍❄️ 🦭

🌲 Forest

Trees, rain, deer, bears, birds

🌊 Ocean

Salt water, fish, whales, octopuses

🏜️ Desert

Hot, dry, lizards, camels, hawks

❄️ Arctic

Very cold, ice, penguins, polar bears

🌾 Grassland

Grass, lions, zebras, elephants

🏞️ Pond

Fresh water, frogs, fish, ducks

🏡 Good Habitat Needs:

✓ Food to eat

✓ Water to drink

✓ A safe place to rest (shelter)

✓ Space to move around

Animals & Their Habitats

Different animals are adapted to live in their habitats. They have special features that help them survive!

🐠 Fish

Habitat: Water (oceans, rivers, lakes)

Adapted for: Swimming with fins, breathing with gills

🦅 Birds

Habitat: Air and trees

Adapted for: Flying with wings, seeing far away

🦁 Land Animals

Habitat: Ground (forests, grasslands, deserts)

Adapted for: Walking/running, hunting or hiding

🐢 Reptiles

Habitat: Warm places

Adapted for: Tough skin, cold-blooded

Adaptations

Animals have special features that help them fit their habitat:

  • 🦑 Octopus changes color to hide in the ocean
  • 🦒 Giraffe has a long neck to reach tall trees
  • 🐪 Camel stores water for desert heat
  • 🐧 Penguin has thick fur to stay warm in Arctic

Herbivores, Carnivores & Omnivores

Animals eat different things! Let's learn about three groups based on what they eat.

🌱 Herbivore

🦌🐰🦋

Eats: Plants only

Leaf-shaped teeth for grinding

🥩 Carnivore

🦁🐯🦅

Eats: Meat only

Sharp teeth for tearing

🍎 Omnivore

🐻🐷👨

Eats: Plants & meat

Mixed teeth for both

👂 Listen to Your Teeth!

Flat teeth = herbivore (grinding plants)

Sharp teeth = carnivore (tearing meat)

Mixed teeth = omnivore (both foods)

Food Chains

A food chain shows how energy moves from the sun through plants and animals. Every living thing depends on another!

Sun Plant 🐰 Herbivore 🦅 Carnivore

Food Chain Parts:

☀️ Producer (Plant): Makes food from sun's energy

🐰 Primary Consumer (Herbivore): Eats the plant

🦅 Secondary Consumer (Carnivore): Eats the herbivore

The sun gives energy to plants. Plants give energy to herbivores. Herbivores give energy to carnivores!

Ocean Food Chain

☀️ → 🌱 (algae) → 🐠 (small fish) → 🐋 (whale)

Grassland Food Chain

☀️ → 🌾 (grass) → 🦓 (zebra) → 🦁 (lion)

Life Cycles

How plants and animals grow and change

What is a Life Cycle?

All living things go through changes from birth to death. These changes are called a life cycle. Every plant and animal has one!

🥚 Stage 1 ➡️ Stage 2 ➡️ Stage 3

All Life Cycles Have:

  • Birth - The living thing begins
  • Growth - It gets bigger and changes
  • Adulthood - It becomes full grown
  • Reproduction - It makes babies
  • Death - The cycle ends

🌍 Did You Know?

Every plant and animal you see has already lived part of its life cycle! You're in your childhood stage of YOUR life cycle!

Plant Life Cycles

Plants grow in stages: from a tiny seed to a full plant that makes flowers and new seeds!

Seed Sprouting Seedling Growing Flowering

🌰 Seed

Small, hard, has baby plant inside

🌱 Germination

Seed wakes up and roots start growing

🌿 Seedling

First leaves appear above soil

🌳 Plant

Grows bigger, more leaves and stems

🌸 Flower

Bloom with colors, make seeds

🍎 Fruit

Protects seeds, ready to spread

What Seeds Need to Grow:

💧 Water - Wakes up the seed

☀️ Sunlight - Helps plant make food

🌡️ Warmth - Right temperature for growing

🌍 Soil - Food and place for roots

Insect Life Cycles

Insects change a lot during their life cycles! A butterfly's life cycle is one of the most amazing.

Egg 🥚 Caterpillar 🐛 Chrysalis 🎭 Butterfly 🦋

🦋 Butterfly Life Cycle

1. Egg - Parent lays tiny eggs

2. Caterpillar - Eats leaves, grows big

3. Chrysalis - Covers itself, transforms

4. Butterfly - Beautiful wings, can fly!

🐸 Frog Life Cycle

1. Eggs - Laid in water (jelly clumps)

2. Tadpole - Lives in water, has tail

3. Metamorphosis - Grows legs, loses tail

4. Frog - Lives on land and water

✨ Metamorphosis

This is an amazing change! The insect completely changes shape and form, like magic!

Animal Life Cycles

Different animals have different life cycles. Let's compare some!

🐕 Mammals

Baby born alive, fed mother's milk, grows slowly

Examples: dogs, humans, whales, bears

🐦 Birds

Eggs laid in nest, babies hatch, parents feed them

Examples: robins, eagles, chickens, penguins

🐢 Reptiles

Eggs laid in warm places, babies hatch alone

Examples: snakes, lizards, turtles, crocodiles

🐠 Fish

Many eggs laid in water, babies swim alone

Examples: salmon, goldfish, sharks, tuna

Life Cycle Stages Comparison:

Mammal Baby → Childhood → Teen → Adult
Bird Egg → Chick → Teen → Adult
Butterfly Egg → Caterpillar → Chrysalis → Butterfly
Frog Egg → Tadpole → Froglet → Frog

Spelling & Punctuation

Master the rules of writing

Prefixes: un-, dis-, mis-, re-

A prefix is a word part you put at the beginning of a word. It changes the word's meaning! Prefixes are like building blocks that help you understand and create new words.

Prefix Building Blocks UN- Means "not" happy → unhappy DIS- Means "opposite" like → dislike MIS- Means "wrong" spell → misspell RE- Again do → redo Word Examples with Prefixes UN-: unlock, undo, unpack, unfair, unknown DIS-: disagree, disobey, disconnect, discover MIS-: misbehave, misread, misjudge, miscount RE-: rebuild, rewrite, replay, retell, restart Can you think of more words with these prefixes?

Try It Yourself!

Put the prefix with the word:

• un + kind = unkind

• re + paint = repaint

• dis + appear = disappear

• mis + place = misplace

Prefix Power: Once you know prefixes, you can understand NEW words you've never seen before! That's the superpower of prefixes!

Suffixes: -ly, -ful, -less, -ness

A suffix is a word part you put at the END of a word. Like prefixes, suffixes change the word's meaning. They help describe HOW something happens or what someone is like!

Suffix Word Building -LY How something is done quick → quickly -FUL Full of care → careful -LESS Without care → careless -NESS Quality sad → sadness Word Examples with Suffixes -LY: slowly, happily, carefully, quickly, badly -FUL: beautiful, helpful, wonderful, grateful, hopeful -LESS: helpless, hopeless, fearless, homeless, endless -NESS: kindness, sadness, darkness, silliness, happiness What new words can you create with these suffixes?

Compare Meaning Changes

care: being careful about something

careful: full of care, paying attention

careless: without care, not paying attention

carefulness: the quality of being careful

Tip: Sometimes you drop a letter when adding a suffix. "Hope" becomes "hopeful," but "hate" becomes "hateful" (no 'e')!

Apostrophes

An apostrophe (') is a small curved mark that shows two things: 1) When letters are left out (contractions), and 2) When something belongs to someone (possessives).

Apostrophes: Two Jobs Contractions: Joining Two Words An apostrophe shows where a letter is missing when two words join do notdon't (the 'o' is left out) cannotcan't (the 'no' is left out) will notwon't (whole word changes!) I amI'm | she isshe's | they arethey're Possessives: Showing Ownership An apostrophe shows that something belongs to someone Sarah's book = the book belonging to Sarah The cat's tail = the tail belonging to the cat Tom's pencil = the pencil belonging to Tom

Common Contractions

I am → I'm | you are → you're | he is → he's | she is → she's | it is → it's | we are → we're | they are → they're | that is → that's

Important: "Its" (without apostrophe) = belonging to it. "It's" (with apostrophe) = "it is"! These are easy to mix up!

Speech Marks (Quotation Marks)

Speech marks show exactly what someone said. They go around the words a person speaks. This is called "direct speech" or "dialogue."

Using Speech Marks Sarah said, "I love to play!" The speech marks show exactly what Sarah said. Tom asked, "Want to play with me?" Question marks go inside the speech marks! Rules for Speech Marks • Put speech marks around the exact words someone says • Punctuation (. ! ?) goes INSIDE the speech marks • Start a new line when a different person speaks

Example Dialogue

"Do you want to go to the park?" asked Maya.

"Yes! Can we go on the swings?" said Jake.

"Of course!" laughed Maya.

Dialogue Tip: When you write stories, dialogue makes them come alive! It shows what people say and how they feel!

Homophones & Tricky Spellings

Homophones are words that sound the same but have different spellings and meanings. They can be tricky, but once you learn them, your writing will be much better!

Common Homophones

there / their / they're

there = a place ("Put it there.")

their = belonging to them ("Their house is big.")

they're = they are ("They're coming soon.")

More Homophones

to / too / two: "I want to go too! That makes two of us."

hear / here: "Can you hear me? I'm over here!"

see / sea: "I can see the sea from my window."

know / no: "I know there is no time left."

write / right: "Please write the right answer."

Tricky Spellings

Some words don't follow the rules! Here are common tricky words:

Silent letters: knight, write, comb, know

ph = f sound: phone, photo, elephant

Common mistakes: their (not thier), because (not becuz), friend (not freind)

Memory Trick: "There" has "here" in it — both are about places! "Their" has "heir" in it — both are about belonging!

Phonics & Word Patterns

Master vowel sounds, blends, and tricky spellings

Short & Long Vowels

Vowels (a, e, i, o, u) can make two different sounds: short sounds and long sounds. The "magic e" at the end of a word often makes the vowel say its name (long sound)!

Short Vowel Sounds

CVC Words (Consonant-Vowel-Consonant)

cat, hat, bat, mat, rat

sit, bit, fit, hit, kit

The vowel says its short sound!

Long Vowel Sounds

CVCe Words (with magic e)

cake, make, lake, take, bake

site, bite, kite, mite, quite

The vowel says its name!

Vowel Teams

Sometimes two vowels work together to make a sound:

ai makes long "a": rain, pain, mail, sail

oa makes long "o": boat, coat, road, toad

ea makes long "e": seat, meat, beat, heat

ee makes long "e": tree, free, bee, see

oo makes long "oo": moon, soon, room, book

Blends & Digraphs

Blends and digraphs are pairs of consonants at the beginning or end of words. They sound different and work differently!

Consonant Blends

In a blend, you hear both sounds: bl, br, cl, cr, dr, fl, fr, gl, gr, pl, pr, sl, sm, sn, sp, st, sw, tr

Examples: blue, brick, clock, crab, drip, flag, fresh, glass, green, plant, prince, sleep, small, snake, spot, star, sweet, tree

Consonant Digraphs

In a digraph, two letters make one new sound: sh, ch, th, wh, ph

sh makes one sound: ship, fish, wish, shell

ch makes one sound: chair, chip, lunch, beach

th makes one sound: that, think, with, bath

wh makes one sound: what, when, where, white

ph makes an "f" sound: phone, photo, elephant

Silent Letters

Some letters in words don't make a sound! They are silent. Learning these patterns helps with spelling.

Common Silent Letter Patterns

kn: knight, know, knee, knit, knock

wr: write, wrong, wrap, wrist, wreck

mb: comb, climb, lamb, thumb, dumb

gn: gnaw, gnat, sign, align

Silent Letter Tip: When you see "kn" at the start, the "k" is silent — you only say the "n" sound. When you see "wr" at the start, the "w" is silent — you only say the "r" sound!

Compound Words

A compound word is made when two smaller words join together to make a new word with a new meaning!

How to Build Compound Words

sun + flower = sunflower

rain + bow = rainbow

bed + room = bedroom

tooth + brush = toothbrush

butter + fly = butterfly

cup + cake = cupcake

Practice: Can you break these compound words into two smaller words? "baseball" = base + ball. "playground" = play + ground. "someone" = some + one.

Vocabulary & Word Meaning

Synonyms, antonyms, homophones, and context clues

Synonyms

Synonyms are words that mean almost the same thing! Using synonyms makes your writing more interesting and helps you avoid repeating the same words.

Synonym Examples

happy = glad, joyful, cheerful, delighted

big = large, huge, enormous, gigantic

small = tiny, little, wee, miniature

fast = quick, speedy, rapid, swift

sad = unhappy, miserable, gloomy, sorrowful

Writer's Tip: Instead of writing "The cat is big and the elephant is big," you could write "The cat is big and the elephant is enormous!" Using synonyms makes your writing more interesting!

Antonyms

Antonyms are words that mean the opposite! Learning antonyms helps you express contrasts and opposite ideas.

Antonym Pairs

hotcold

bigsmall

happysad

fastslow

lightdark

oldnew

cleandirty

loudquiet

Homophones

Homophones sound the same but are spelled differently and mean different things. They can be tricky!

Common Homophones

there / their / they're — "Put it there. Their house is big. They're coming soon."

to / too / two — "I want to go too! That makes two of us."

hear / here — "Can you hear me? I'm over here!"

see / sea — "I can see the sea from my window."

write / right — "Please write the right answer."

know / no — "I know there is no time left."

Context Clues

When you see a word you don't know, the words around it can give you clues about what it means. These are called context clues!

Using Context Clues

Example: "The brilliant scientist discovered something amazing."

From the context, you can guess that brilliant means smart or clever, because it's describing a scientist who made an amazing discovery!

More Examples

"The dog was famished after playing all day." → famished means very hungry

"She was elated to win the contest." → elated means very happy

"The child was lethargic and could barely stay awake." → lethargic means tired or slow

Sentences & Writing Skills

Master sentence types, tenses, and writing techniques

Complete Sentences

A complete sentence has two important parts: a subject (who or what) and a verb (action or state of being). Without both parts, you have a fragment (incomplete sentence).

Complete vs Incomplete

Complete: "The cat sleeps." (subject: cat, verb: sleeps)

Fragment: "The big red" (missing verb)

Fragment: "Running fast" (missing subject)

Complete: "She runs quickly." (subject: she, verb: runs)

Check for Completeness: Ask yourself: "Who or what is doing something?" and "What action is happening?" If you can answer both questions, you have a complete sentence!

Four Sentence Types

Sentences can have different purposes. Knowing the four types helps you write for different reasons and punctuate correctly.

The Four Types

Statement: Tells information. Ends with a full stop (.). "The sky is blue."

Question: Asks something. Ends with a question mark (?). "What time is it?"

Command: Tells someone to do something. Ends with a full stop (.). "Please sit down."

Exclamation: Shows strong feeling! Ends with an exclamation mark (!). "What a beautiful day!"

Verb Tenses

Verbs show when something happens: past, present, or future!

The Three Tenses

Past Tense: Already happened. Add -ed to regular verbs: walked, played, jumped

Present Tense: Happening now: walk, play, jump

Future Tense: Will happen. Use "will": will walk, will play, will jump

Irregular Verbs (Don't Follow the Rules!)

run → ran, go → went, see → saw, eat → ate, make → made, come → came, take → took, give → gave

Conjunctions

Conjunctions join ideas together and show relationships between them.

Key Conjunctions

AND adds ideas: "I like cats and dogs."

BUT shows contrast: "I like cats but I'm allergic."

OR gives choices: "Do you want tea or juice?"

SO shows results: "It was raining so we stayed inside."

BECAUSE gives reasons: "I'm happy because it's my birthday."

Fact vs Opinion

A fact can be checked and proven true. An opinion is what someone thinks, believes, or feels.

Examples

Fact: "The Earth orbits the sun." (Can be proven true)

Opinion: "The sunset is beautiful." (What someone thinks)

Fact: "Dogs have four legs." (Can be proven true)

Opinion: "Dogs are the best pets." (What someone believes)
