Check understanding
- Count and describe the faces, edges, and vertices of a triangular prism and a square-based pyramid
- Describe the 2-D cross-section produced by slicing a cylinder horizontally or a cone vertically
- Use properties of 3-D shapes to determine whether a given net will fold into a specified solid
“If your child slices a cylinder straight across the middle like cutting a tin of beans in half, can they describe the shape of the cut surface? What about slicing at an angle?”
