This little toy is a fascinating work of origami invented by Martin Gardner, a Mathematician and magician from U.S.A. These little origami toys are made form only one slip of paper and are a great way to work with equilateral triangles hands on. Hope you enjoy!
Some ideas for decorating:
Use the flexagon as a learning diary, where students write and draw on the faces the things they remember most from the term.
Use the flexagon as and encrypted messaging device. The faces could hold the secret password!
This is the same toy as before, also made from only one strip of paper, however once complete shows 6 faces rather than 3. It is AMAZING, magical in itself!
