This is a fun way for your students to practice symmetry. Students choose any card to start on. They read the problem and solve it. Once they have the answer, they record it on the answer sheet. They will need to search the room for another card that has that answer on it. Once they find it they will see their next problem. 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! My students are actually excited to do the work. The 16 cards correlate with 4.G.A.3 from the fourth grade common core math objectives.
