How to play: Each student will need one mat (with the frog and lily pad), one cup of black beans (These are the flies- I use a Dixie cup for distributing small manipulatives. They will only need about 10 beans.) Each table will need one set of subtraction cards.
Students pick a card, read the sentence and then use the mat to subtract. So, if I got 5-2, I put 5 black flies on the lily pad and then the frog eats two flies. So I drag two over to the frog. I count how many I have left and write my sentence.
