Lesson Details
Key learning points
- Understand how to sort shapes into 2 sets using the criteria 'has' and 'has no'.
- Cuboids have rectangular faces and cubes have square faces.
- Cylinders and cones both have some circular faces.
- Pyramids always have some triangular face and may have a different shape face as a base.
Common misconception
Children might begin to confuse 2D and 3D. For example, describe a cube as a square.
Use geometric construction materials to explore the 2D shapes within 3D shapes. Look for familiar 3D shapes in the environment and discuss.
