Each of the nets of nine solid shapes has been cut into two pieces.
Can you see which pieces go together?
60 pieces and a challenge. What can you make and how many of the
pieces can you use creating skeleton polyhedra?
A very mathematical light - what can you see?
two 3-D shapes, the tetrahedron and the octahedron have the same
2-D shape, an equilateral triangle, as their faces.
you arrange the shapes below in a chain so that each one shares a
face (or faces) that are the same shape as the one that follows it?
(The faces do not have to be the same size.)
