This is an I have, Who has game I made for math atory problems. There are 20 cards which each contain a story problem and the answer to another problem. The first student starts by reading the problem in his/her card (ignoring the number at the top). The class then solves the problem and whoever has the anser to that problem on his/her card shouts it out and then reads the problem on their card. The answer to the final story probolem read will be on the first person's card.
These problems use lower numbers, so the students do not need to know how to carry or borrow yet.
