I created this product to use as a math center game. On the blank playing board, I randomly filled in the squares with numbers 1-20. Since it is a partner game, I made four different playing cards and then made copies of those four rather than making all different playing cards.
You may notice that there are "Wild Cards"--I made these after I realized that the lower numbers would come up less often in the stack of cards. So, if students catch on, they will use the "Wild Card" to cover up numbers like 1, 2, etc.
