This is a fun way for your students to practice identifying different types of quadrilaterals. The quadrilaterals used are square, rectangle, rhombus, trapezoid, and parallelogram. Students choose any card to start on. After scanning the QR code using an I-Pad or other electronic device 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 and technology 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.2 from the fourth grade common core math objectives. This product is also available in a non-QR code format.
