Mathematical Origami

 

 

Introduction

Traditional Origami ((the art of paper folding) has no cutting or sticking and everything is made from one piece of paper.  The rules are bent here to make the multi-piece models we make at Maths Club.  We make one shape repeatedly from A4, A5 and A6 paper in order to get the shapes to have the same ratio We then sellotape and glue them together to produce bigger shapes.  The two shapes we make are the Octagon from 8 Isoceles triangles and a large square from 9 squares.

What you need

To make the Octagons - Blue 4*A4, 4*A5, 4*A6
                                    Green 4*A4, 4*A5, 4*A6

Shape based on 8 lots of  Isoceles triangle.in 3 different sizes

The square

Made from 9 lots of squares in 3 different sizes.
