Working with origami paper reminded me of a project we did last summer...flexagons!
Watch this *awesome* video from Vi Hart to learn more about hexaflexagons. Vi Hart truly makes math fun!
You can find templates for these little guys at a bunch of different websites. Here are a few:
- Gathering for Gardner - has colorful ones and blank templates
- Aunt Annies Crafts - template for a tri-hexaflexagon
- Aunt Annies Crafts - template for a hexa-hexaflexagon
- Mathematische Basteleien - Tons of info and shows tetra-hexaflexagons
This is a picture of us from last year learning how to flex our flexagons while we ate pizza! I challenge you to flex and eat (or some other task) at the same time!
This year, I came across a neat tutorial for making Flextangles at Babble Dabble Do!
And, of course, I had to give that a try! Here is my flextangle flexing through its iterations. They are a bit easier to put together than a normal flexagon, and they're fun to flex about, but real flexagons have hidden secrets that make them even more exciting to play with! So give some of these shapes a flex yourself and see what you think!
