Area for children
Count squares and use rectangles to understand area.
Quick answer
Area is the amount of space inside a shape. You can find it by counting squares or using rectangles.
Learning outcome
By the end of this page, you will understand that area is the space inside a shape and can be found by counting squares or using multiplication with rectangles.
- You can count squares to find the area of a shape.
- You can use rectangles to work out area quickly.
- You know how area is used in real life, like when you pack a box or draw a garden.
- You can solve simple area problems with shapes and numbers.
Why this matters
Knowing how to find area helps you solve everyday problems. For example, if you want to cover a floor with tiles, you need to know the area. If you are planning a garden, you need to know how much space you have. Area is also important in games, like when you build with blocks or draw shapes on paper. Understanding area helps you think about space and how things fit together.
How it works
Area is the amount of space inside a shape. To find area, you can:
- Count squares inside a shape.
- Use rectangles and multiply length by width.
For example, if you have a rectangle that is 4 squares long and 3 squares wide, you can count all the squares or multiply 4 by 3 to get 12 squares.
Examples you can see
Let’s imagine you are drawing shapes on squared paper. Here are some examples:
| Shape | Length | Width | Area |
|---|---|---|---|
| Rectangle | 5 squares | 3 squares | 15 squares |
| Rectangle | 6 squares | 2 squares | 12 squares |
| Square | 4 squares | 4 squares | 16 squares |
You can also use a rectangle to help find the area. If a rectangle is 4 squares long and 3 squares wide, you can multiply 4 by 3 to get 12 square units. This works for any rectangle!
Try it as a mini adventure
Adventure: The Garden Planner
You are going to plan a small garden in your backyard. You have a space that is 6 squares long and 4 squares wide.
- Draw this garden on squared paper.
- Count how many squares are in your garden.
- Now, multiply 6 by 4 to check your answer.
- Draw a second garden that is 5 squares long and 3 squares wide.
- Count the squares and multiply to check your answer.
Great job! You’ve planned two gardens and found their areas.
Common mistakes
- Mistake: Thinking that area is the distance around the shape.
Why it happens: Confusing area with perimeter.
Fix: Remember area is the space inside the shape, not the outside. - Mistake: Forgetting to use the same units when multiplying.
Why it happens: Not paying attention to measurement units.
Fix: Always write the units, like square centimeters or square meters. - Mistake: Counting only some squares or missing some.
Why it happens: Not being careful or organized.
Fix: Count row by row or column by column to make sure you don’t miss any.
Parent and carer guide
Helping your child learn about area is easy and fun!
- Play with squares: Use graph paper or draw shapes and count squares together.
- Real life: When cooking, ask your child to measure ingredients in a bowl or pan. This helps with understanding space.
- Games: Try building with blocks or drawing shapes on paper. Ask how many squares are inside.
- Encourage: Let your child try different ways to find area. They might count or multiply. Both are good!
- Watch out: If your child mixes up area and perimeter, remind them that area is about space inside, not around.

FAQ
What is area?
Area is the amount of space inside a shape. You can think of it like how much carpet you need to cover a floor.
How do I find the area of a rectangle?
You multiply the length by the width. For example, a rectangle that is 4 squares long and 3 squares wide has an area of 12 squares.
Can I find area by counting squares?
Yes! If you draw a shape on squared paper, you can count how many squares fit inside it to find the area.
Why is area important?
Area helps you know how much space you have for things like gardens, rooms, or toys. It is also used in art, cooking, and building.
Can I use area with real measurements?
Yes! When you measure in centimeters or meters, you can still find area by multiplying length and width. For example, a room that is 5 meters long and 3 meters wide has an area of 15 square meters.
