This is a fun way for your students to practice with the three types of basic types of angles - acute, right, and obtuse. Students choose any card to start on. They use an I-Pad or other electronic device to scan the QR code. They solve the problem and record their answer 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 have their next QR code to scan. 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.A.1 from the fourth grade common core math objectives.
This is also available in a non-QR format.
