Describe and name 3d shapes – prisms and pyramids
I can recognise and name pyramids and prisms and describe their properties.
Lesson details
Key learning points
- A prism is a 3D shape that has identical opposite polygon faces at each end which are joined by rectangular faces.
- A pyramid is a 3D shape that has a base and an apex at the opposite end to the base.
- A prism always has two opposite, identical polygon faces. A prism can be named after its identical polygon faces.
- A pyramid has a polygon as its base, which is the face opposite the apex. A pyramid can be named after its base.
Keywords
Prism - A 3D shape that has two opposite, identical polygon faces, joined by rectangular faces.
Pyramid - A 3D shape that has a base and an apex at the opposite end to the base, joined by triangular faces.
Common misconception
Children may find it difficult to name the shape of the faces that cannot be seen in drawings of 3D shapes.
Provide 3D shapes for children to handle alongside the drawings. Encourage them to visualise the shape rotating to help them identify and describe each face of the shape.
