Now fold your paper in half hamburger style and make 3 vertical cuts along the inside creases of your puzzle- but only to that first horizontal crease...not all the way to the end! Once you have made your cuts it is easy to maneuver your paper by bending and folding one way and another to try to make a square showing all four of a certain number. I have completed solutions for one and two of the puzzle as an example for you below.
Students will work so quietly trying to find all eight of the possible solutions to this number puzzle. I like taking a few of these number puzzles along with me when we take state assessments in the computer lab. Keeps students busy and entertained when they finish testing before their classmates.
