This document provides instructions for creating a trihexaflexagon, a paper model that can be flexed to reveal different faces. It explains how to mark and cut a sheet of paper to form the necessary shapes and labels. Detailed steps are given for folding the paper according to the markings to form a hexagonal shape. Additional instructions describe how to flex the completed model by folding edges together to reveal different triangle combinations on each face.

1. Math, Art, and Design: Creating a TriHexaFlexagon<br />A flexagon is a flat paper model that can be folded (aka flexed) to reveal hidden faces. Flexagons were invented by a Princeton student in the 1930’s and popularized by Martin Gardner. Some of the material here comes from http://www.instructables.com/id/How-to-make-a-hexaflexagon/ and http://www.flexagon.net/. <br />Your paper needs to be trimmed down to 24 cm across. Then mark every 4 cm along the top edge of the paper.
