Lesson Details
Key learning points
- 3D shapes can be discussed and compared by their properties.
- The properties of 3D shapes are the faces, edges and vertices.
- 3D shapes can be compared using informal language such as taller, shorter, wider, narrower, smaller and larger.
Common misconception
Children may think that the tallest shape is always the largest.
Explore lots of different 3D shapes of different proportions. Allow children to handle and rotate the shapes. Use hollow shapes and explore filling them with water or sand to help children see that the largest shape is the one that can hold the most.
Keywords
Compare - You compare to find out what is the same and what is different.
Faces - The flat 2D surfaces of a 3D shape.
Vertices - The corners of a shape where two or more edges meet.
Edges - The straight lines where two faces of a 3D shape meet.
