3D Shape Nets

Two square based pyramid nets. One has the square face at the centre with a triangle come off each side. The other has the triangles in a row with the square off the bottom

Description of the model

Nets of common 3D shapes. Joints are hinged with interlocking teeth on other edges. There are multiple versions of the cube and square based pyramid to demonstrate that the same shape can be made from two very different nets. Also one ‘not’ net for each to show that not all combinations of those faces create that shape.

Nets include

  • 3 x Cube and one ‘not’ cube
  • 2 x Square Based Pyramid and one not pyramid
  • Rectangular Prism
  • Triangular Prism
  • Cylinder
