This game is well known to all teachers. Just print the file, cut and laminate. Then play and learn. This is great for small and large groups. You can remove some of the cards because I have made a few that have the same answer. For example: 2x8 and 8x2. I like it. I hope you do, too.
There was a small problem with the file. I fixed it and now it's ready for you to use. Enjoy!
