Here are 18 addition and 18 subtraction problems to use with the iPad or any tablet. The idea of the lesson is that you can cut the problems out and hide them in Easter Eggs around the room.
When students find an egg, in order to keep that egg they must correctly answer the math problem. Using a free QR reader that you can find in any app store, students can check their answer. If they are correct, they keep the egg. If they are incorrect, they must place the egg back in the hiding spot.
