Lesson Details
Key learning points
- 3D shapes can be sorted by their properties
- The properties of 3D shapes are the faces, edges and vertices
Common misconception
Children may still find it difficult to count the number of faces, vertices and edges on a 3D shape when they are looking at an image of that shape.
Provide 3D shapes for the children to handle. Encourage them to mark the faces, vertices and edges with a wipe-clean pen as they count. Talk about where the properties can be found on each shape e.g. a triangular prism has 3 vertices at each end.
Keywords
Faces - The flat 2D surfaces of a 3D shape.
Edges - The straight lines where two faces of a 3D shape meet.
Vertices - The corners of a shape where two or more edges meet.
