Introduction

The following shapes are made from Circles cut out from paper of different colours.   The triangular pattern can make a 4 sided Tetrahedron or an 8 sided Octahedron.   The petagon pattern makes a 12 sided dodecahedron.  Its useful to have lots of staplers so lots of groups can make up the shapes.  It is useful to fold the flaps back on each shape so that the edges of the shape marry up

Constructing a tetrahedron

Staple 3 together to form an open based tetrahedron then staple the fourth onto the bottom.

Constructing a Octahedron

Staple 4 together to form an open based square pyramid, repeat and staple these two pyramids together.

Constructing a Dodecahedron

Use the pentagon shaped pieces and staple 3 together at each corner.

Constructing an Icosahedron

Again use the pentagon pieces, and join five together at each corner.
