Identify 2D shapes within 3D shapes

I can describe the individual faces on 3D shapes.

Lesson details

Key learning points

  1. Recognise and know the difference between flat faces and curved surfaces.
  2. Know that when a shape is lying on a curved surface it will roll.
  3. Know that when a shape is lying on a flat face it will slide.
  4. Know that 3D shapes can have different shaped faces. For example, cones and cylinders have some circular faces.

Keywords

  • Curved surface - A rounded surface that is not flat.

  • Face - Any of the flat surfaces of an object.

  • Square face - The flat surface of a 3D shape that is shaped like a square with four sides that are equal in length.

  • Rectangular face - The flat surface of a 3D shape that is shaped like a rectangle with four sides.

  • Circular face - The flat surface of a 3D shape that is shaped like a circle with one curved line.

Common misconception

May think that a sphere has a circular face because when drawn, a sphere looks like a circle.

Physically handle and compare spheres, cylinders and cones. Explore why a sphere cannot stand but a cylinder and a cone can.

It is really important to have a range of 3D shapes ready before teaching this lesson. The teacher will need them to demonstrate throughout the lesson, and the children will hugely benefit from the opportunity to explore 3D shapes too.
