Overview

Discover the unusual math of twisted strips of paper

Flexagons are twisted strips of folded paper, which reveal their properties when flexed.

This online course will explain what flexagons are, their history and their naming conventions. You’ll find out how to create your own flexagons and be able to share them with our global community of learners.

You’ll also explore mathematical fields that provide tools to analyze flexagons, including topology and graph theory and learn about Möbius strips, Tuckermann diagrams and more.

This course is aimed at learners who enjoy being creative, solving puzzles, folding paper and revealing hidden mathematics. It will also help mathematics teachers who are looking for material for enrichment programs.

by Ricardo completed this course, spending 2 hours a week on it and found the course difficulty to be easy.
This is a good introduction to flexagons, I suppose.

It's quite easy to follow through, and it introduces very interesting concepts which one couldn't have imagined at first, like Möbius strips, magic squares and Catalan numbers.

For the most part, it's a hands-on course in which you'll have to print and cut the templates for the flexagons, and play with them a little bit in order to get confident with the flexes and going through the different faces of the flexagon.

But as I said, there are very interesting concepts too related with the flexagons.
