Identify 2D shapes within 3D shapes
I can describe the individual faces on 3D shapes.
Lesson details
Key learning points
- Recognise and know the difference between flat faces and curved surfaces.
- Know that when a shape is lying on a curved surface it will roll.
- Know that when a shape is lying on a flat face it will slide.
- 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.
