A key principle for learning mathematics is to move from the concrete to the abstract, which implies having “active mathematical experiences” first. Paper folding is one avenue for such experiences. Concepts of perpendicularity, parallelism, similarity, congruence and symmetry are easily experienced through paper folding activities and provide an experiential base for further learning. Paper folding also lends itself readily to explorations, visual proofs and constructions. Angle trisection and doubling of a cube which are not possible with straightedge and compass and the traditional rules of Euclidean constructions are possible using paper folding.
