Geometrical Shapes by Paper Folding

Origami is the art of paper folding without the use of either scissors or glue. Each of the beautiful and fundamental mathematical shapes described in this book is achieved by folding sheets of standard A4 paper. It is remarkable what can been done and David Mitchell gives clear step by step instructions for each. He has gathered together a most impressive collection which will amaze and interest mathematics teachers and other admirers of pure geometrical forms. This second edition extends the models considerably - adding 60 new pages of activities.

The models have been divided into Convex and Planar Polyhedra and Rhombic Polyhedra - using modular origami to the maximum effect.  Full contents are:
