ABSTRACT
Origami is a simple and accessible activity for learning mathematics. It allows learners to explore important mathematical topics and solve problems. Paper is a relatively cheap practical resource for classroom use. Any practical activity can enhance learning by making it more memorable. Folding paper is an inherently mathematical activity: folding a point onto another creates a perpendicular bisector, folding repeatedly in half easily creates fractions of quarters and eighths. However, folding paper does not automatically teach mathematical concepts as much as walking does not necessarily teach you biomechanics. This chapter is aimed at primary and secondary school mathematics teachers. It will also be valuable for anyone interested in using origami for teaching and learning. First, common folding problems are described and advice given on how to avoid them. The next section describes eleven activities that can be used with almost any origami model. Then opportunities for learning some specific mathematical topics are given.
