How to make a TRIFLEXAGON

If you've seen Kjartan (the author) talking about the Murderous Maths books, he probably demonstrated some of his different FLEXAGONS.

A flexagon looks like a piece of folded card which you can turn inside out. The good bit is that you're never quite sure what you'll see next.

You also need...
  • scissors

  • some pens or pencils
Follow the instructions on the video. Good luck!

If you are wondering how the little flexagon at the end of the video works, it's a hexaflexagon.
A tri-flexagon has got three different faces, a hexaflexagon has got six!
