Knight maths quest: area
A story-led junior maths adventure using quests, shields and tournament scores to cover floors, gardens and maps with squares.
Quick answer
Area is the amount of space inside a flat shape, and you can find it by counting how many square units fit inside it.
Learning outcome
By the end of this page, you will be able to find the area of a shape by counting squares or using multiplication.
Success signs:
- You can tell the difference between area and perimeter
- You can count squares to find area
- You can use multiplication to find area of rectangles
- You can solve real-world area problems
Why this matters
Area helps you know how much space you have for things like playing, building, or putting down a carpet. When you're a knight, you need to know how big your shield is or how much space you have to fight in. In real life, area helps you work out how much paint you need for a wall, how big your garden is, or how many tiles you need for your floor.
How it works
Area is the amount of space inside a shape. You can find it by:
- Counting how many squares fit inside the shape
- Multiplying the length by the width for rectangles
- Breaking complex shapes into rectangles
Think of it like covering a floor with square tiles. The number of tiles needed tells you the area.
Examples you can see
Imagine you're a knight preparing for battle. Your shield is a rectangle that is 3 squares wide and 4 squares tall. How much space does your shield cover?
| Width | Height | Area (squares) |
|---|---|---|
| 3 | 4 | 12 |
You can see this by drawing a grid:
□ □ □
□ □ □
□ □ □
□ □ □
That's 3 rows of 4 squares = 12 squares total.
Let's try another example: A garden is 5 metres long and 3 metres wide. What is its area?
Area = length × width = 5 × 3 = 15 square metres
Imagine laying out 15 square metre tiles to cover the garden.
Try it as a mini adventure
Quest: The Knight's Garden
You are a brave knight preparing for the Royal Tournament. Your mission is to plan a garden for the castle. You have a square plot of land that is 6 squares wide and 6 squares long.
1st time: How many square units of land do you have to plant flowers in?
2nd time: You want to plant roses in a 4 square by 3 square section. How much area is that?
3rd time: You need to build a fence around the whole garden. How much fencing do you need? (That's perimeter, not area!)
4th time: You want to plant a vegetable patch that is 2 squares wide and 5 squares long. What is the area of your vegetable patch?
5th time: You need to cover the garden with grass seed. Each packet covers 10 square units. How many packets do you need?
Common mistakes
- Mistake: Thinking area is the distance around the shape (that's perimeter)
Why it happens: Confusing area with perimeter
Fix: Remember: area = inside space, perimeter = outside edge - Mistake: Forgetting to include the unit when writing area
Why it happens: Not paying attention to units
Fix: Always add square units (like square metres or square feet) - Mistake: Counting the edges instead of the inside space
Why it happens: Looking at the outline instead of the fill
Fix: Count only the inside squares - Mistake: Using the wrong formula for shapes
Why it happens: Not knowing when to use multiplication vs. addition
Fix: For rectangles, always multiply length by width
Parent and carer guide
Help your child by:
- Using everyday objects to show area (like a book cover or table top)
- Counting squares together when drawing shapes
- Practising with real items like tiles or blocks
- Playing games where they estimate area before counting
- Encouraging them to explain how they found the area
Watch for:
- Confusion between area and perimeter
- Forgetting to include units
- Counting the outline instead of inside space
Remember: It's okay to make mistakes. They help us learn!

FAQ
What is area?
Area is the amount of space inside a shape. It's like covering a floor with tiles.
How do I find area?
You can count squares inside a shape, or multiply length by width for rectangles.
What units do I use for area?
Area is measured in square units, like square metres or square feet.
What's the difference between area and perimeter?
Area is the inside space, perimeter is the distance around the outside.
Can I use area for anything else?
Yes! Area helps you know how much paint you need, how big a garden is, or how much carpet to buy.
