This is a fun way for your students to practice multiplicative comparison problems. Students will move around the room solving problems. Each card has a problem for students to solve and record the answer on their answer sheet. They will then need to search the room for another card that has that answer on it. Once they find it they will solve the next problem located on that card. It is so much better than a traditional worksheet. The students will have so much fun with the movement that they won't even realize they are doing work! The 16 cards correlate with the fourth grade common core 4.OA.2. This product is also available in a QR Code Format.
