Needs first
- 3-D shapesREQUIRED
Describing 3-D properties (edges, vertices, faces) requires knowing the shapes first
- Nets of 3-D Shapes
Counting edges, vertices, and faces is reinforced by analysing nets where each face is visible as a separate 2-D shape
- 3-D shapes (age 5+)REQUIRED
Formal property description extends informal analysis of shapes
