Before you read this, please see the page on flexagons for an explanation of what a flexagon is.
The tritetraflexagon is the simplest flexagon that can actually be flexed. It can only be flexed one way and then back. It has 3 faces (tri) and 4 sides, meaning that it is square-shaped (tetra). Here are some instructions on building and flexing a tritetraflexagon.
FOLDING
1. Print and cut out the template below.

FOLDING
1. Print and cut out the template below.
2. Fold it in half horizontally, and tape the two halves together so that they can't separate.
3. Fold the line in between the 3's to get a square of 1's and a 2.
Fold the 2 under the 1 adjacent to it, so that only a square remains.
Tape the rightmost squares together in the back, and your tritetraflexagon is ready!
FLEXING
You should now be at a face with only the number 1 on it. Fold it in half so that the right and left edges of the paper come towards you. The paper should now be covered in 2's. Unfold the paper so that the 2's are facing you. You have now flexed to the 2 face. The tritetraflexagon cannot flex any further (except back to 1), so you may be wondering where the 3 face is. It is on the other side of the 2 face.
