3-D shapes (age 11+)
三维立体图形（11岁以上）
Description
Use the properties of faces, surfaces, edges, and vertices of 3-D shapes (cubes, cuboids, prisms, cylinders, pyramids, cones, and spheres) to solve problems, including visualising cross-sections
Mastery Evidence
- 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
Assessment Prompt
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?
