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 recognise, name and compare three different 3D shapes.
Key Notes
- Recognise objects that are similar shapes.
- 3D shapes have 3 dimensions and are not flat.
- A sphere is shaped like a ball.
- A cylinder has 2 flat circle faces.
- A cone has 1 vertex and 1 flat circle face.
Vocabulary To Learn
- Similar: When one thing is like something else.
- Cone: A 3D shape with one vertex, one circular face and one curved surface.
- Sphere: A 3D shape with one curved surface.
- Cylinder: A 3D shape with two circular faces and one curved surface.
Common Mistakes To Avoid
- Children might mix up words that sound alike e.g. similar and cylinder.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Recognise objects that are similar shapes. 3D shapes have 3 dimensions and are not flat.
2. Use this key word in a maths sentence and explain it clearly. 'Similar'
When one thing is like something else. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children might mix up words that sound alike e.g. similar and cylinder. Correction: Allow additional practice for children to name shapes throughout the day, particularly those that are familiar within their environment.
