I made mats like this and my class loves to play. We keep score on the board for who wins each 'hand'. I call out, "Draw 2 (or 3) cards and make the least/greatest number possible." I also made one which includes thousands, for later.
Instead of 100 board cut-outs, try these number puzzles. Students work on one more, one less, ten more, and ten less while putting them together.
