Hexaflexagons

Hallo everyone!

 So today I decided as I math project to make a "How to make Hexaflexagons" thing.
 But what is a Hexaflexagon, you say? A Hexaflexagon is the coolest, awesomest, most amazing thing ever! It's a piece of paper in the shape of a Hexagon that you can flex! They are so much fun.
 I found out about them from the mathmusician Vi Hart. She has such a huge amount of cool maths stuff! I noticed, however, that if one wanted to make a Hexaflexagon from her videos, it is a little difficult. So I've tried to make easy-to-follow instructions for people.

                   How to make a Hexaflexagon


  Tools:

• Paper 
• Sicissors
• Stickytape
• pencil
• felt tip pens
• Ruler

Take the ruler and measure two centimeters from the longest side of the paper.  Cut it out, so that you are left with a long strip of paper. 

 

 Fold the paper on an angle to make an Equilateral triangle. You can then use it as a guide, and continue until all the paper is a nice happy fold of bouncy triangles. :)

 When you have done that, you are now up to making it into the Hexagon shape!



Unfold the triangles. They should look like the ones to the right. Once you've
done that you can fold them into the Hexagon shape. See the images below:

Once you have your ten nice equilateral triangles in the shape of a hexagon,you can cut off the others and glue/stickytape the paper together. 

 It is now officially a Hexaflexagon! All you need to do is colour it and get flexing!

So in the images above you can see that I've coloured one side, "flexed" it, coloured the second side, "flexed" it again and then coloured the third side. When it was flexed the third time we came back to colour one again - side one.

 I hope this is clear, and that many people enjoy the use of Hexaflexagons!!
