b) Photograph or draw your model.

Check student’s drawing or photograph of model for accurate geometric features.

8. a) Tick the name of the three-dimensional object that is the same as the guinea pig hutch.

pyramid triangular prism rectangular prism cone

b) Use mathematical language to describe the features of this three-dimensional object.

A triangular prism is a three-dimensional object that has two triangular faces, equal in size, as the ends or bases. All other faces are rectangular. It has 9 edges, 6 corners and 5 faces.

c) Explain why you chose this name to describe the guinea pig hutch.

The guinea pig hutch has all of these same features.

Part B
