Discuss and compare 3D shapes
Lesson details
Learning outcome
I can discuss and compare the properties of 3D shapes.
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.
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.
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.
Teacher tip
Allow time for children to handle and explore lots of differently-proportioned 3D shapes, including tall, short, wide and narrow examples. This lesson contains the pre-requisite knowledge for later exploration of volume and capacity when comparing size.
