MathsNet and NRich Maths 3D shape resource heaven | Great Maths Teaching Ideas | eew32r |
MathsNet have a wonderful collection of 3D shape resources at this webpage. There are a variety of interactive applets that cover 3D shape topics including nets and 2D views of 3D shapes.

My particular favourite is ‘Building Houses 2′ where pupils have to build the 3D shape by using the 2D views given. They score maximum points by using the minimum number of blocks possible. By clicking and dragging on the 3D view pupils can spin their construction around in real time to help them with the task.
