This interactive activity explains the difference between 2D and 3D shapes. It allows them to explore 2D and 3D shapes and consider their properties.
There are 9 2D shapes in all and 11 3D shapes. There is also a simple worksheet in MS Word format that can be downloaded and printed.
Ideal for whole class work on a whiteboard or research for homework. Unfortunately this activity is Flash based and so will not work on an iPhone or iPad – works fine on a desktop Mac.
