Lesson details
Key learning points
- A net is a 2D shape that can be folded and joined to create a 3D shape.
- There can be more than one way to create a net for a given 3D shape.
- Not all arrangements of shapes will form the net of a 3D shape.
Common misconception
It is perfectly possible for pupils to be highly numerate but struggle with the spatial awareness needed to visualise / imagine whether a 2D net will fold together to form a 2D shape.
As part of the lesson design process you may wish to incorporate manipulatives such as construction materials for those pupils whose learning needs scaffolding. As with all scaffolding, aim to move pupils away from this when you can.
Keywords
