This is a fun way for your students to practice their multiplication skills. Students will move around the room solving problems. They will use an electronic device such as an I-Pad to scan the QR code on one of the cards. This will make a problem pop up. 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 solve the next question that is located on the new card. 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 objective 4.NBT.5 and contain only 1 by 4 digit multiplication problems.
