In this activity, you have 15 cards, answer sheet, and the answer sheet through QR code. I placed the cards throughout the classroom, and the students went card to card and wrote their answers on their answer sheet. When they were done, they went to the QR station, where they scanned the QR and found what letter went with what answer. If they have all the right answers it will spell out homework pass. This was the students reward for answering all the problems correctly! This took my students 75-90 minutes to complete.
The documents are in word so you can modify those but the google doc and QR code can not be changed.
