3-D shape investigation.Shape properties. KS3.

This unit is made up of three mini interactive activities focusing on the properties of 3D shapes. The first activity is based on Euler’s theory. The pupils need to find a rule that links the faces, edges and vertices together. The interactive activity allows them to manipulate the shapes on screen to count the faces, edges and vertices. The second activity has them using their knowledge of the properties of 3D shapes to form a polyhedral chain. The third activity allows the pupils to investigate which edges will meet when a net folds to form a 3D shape.
