This is a fun activity that can be used for most grade levels: grades 3 and up. I will use it with my struggling 9th graders as a numeracy activity, and it also promotes teamwork and cooperation. You'll need to cut up the cards, but that doesn't take too long, and then each student or group gets a set of cards. They have to match the correct fraction, decimal, percent, and picture correctly, then draw it into their answer sheet (the drawing helps the reinforcement). The answer key is in the original way it is set up, before cutting.
