This is a fun way for your students to practice the skills learned in geometry. Students will use an I-Pad or other technology with a QR reader (free at app store) to move around the room solving problems. Each card has a QR code to scan which will then cause a geometry question to pop up on the student's screen. Once they solve it and record the answer on their answer sheet they will need to search the room for another card that has that answer on it. Once they find it they will scan a new QR code to receive their next question. 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 have been begging me to make more of these. They are actually excited to do the activity. The 16 cards correlate with the fourth grade common core 4.G.1, 4.G.2, and 4.G.3.
