This is an additionpuzzle. Unlike your tradition puzzle, the pieces are all squares with problems and answers on each of the sides. Students must solve the problems to create a 3 by 3 square.
I used this with my 5th grade students and they enjoyed it. I made the puzzle spell the name of my dog. They were curious since it was something about me and they learned math at the same time. 2 for 1!
I am currently making a template for anyone to use and create their own. Check back!
