Unit Summary
In this unit pupils will compose, copy, extend and develop repeating and radiating patterns. They will explore, discuss and compare 3D and 2D shapes.
Lesson Summary
You will learn to say if a shape is a circle or not and explain why.
Key Notes
- Describe what the outside of a circle feels like.
- Identify shapes that are circles because they are round and the outside is always an equal distance from the centre.
- Identify shapes that are not circles and explain why.
Vocabulary To Learn
- Circle: A 2D shape that has one curved line which is always an equal distance from the centre.
- Curved: A line or surface that is not straight or flat.
- Centre: The middle of something.
- Equal: The same.
Common Mistakes To Avoid
- Children may think that ovals are also circles.
3 Quick Questions (With Answers)

2. Use this key word in a maths sentence and explain it clearly. 'Circle'
A 2D shape that has one curved line which is always an equal distance from the centre. Use this word when showing your method, then check your final answer is reasonable.
