Flexagons

Some notes on building flexagons with Sam, Max, Eva and Grace, September 16, 2011. Here's the pattern for the RYB.PNG. I printed it from the Windows picture and fax viewer, asking it to fit the image to the page.

This page is the source of the image, and has folding instructions (scroll down). home.adelphi.edu/~stemkoski/mathematrix/flexagon.html Here are the rest of the images we used

the tetrahexaflexagon - front and back
the pentahexaflexagon - front and back

This page is good too: www.flexagon.net/index.php.
