I made this activity for my school's summer reading program and decided to share it with everyone!
Each student or pair of students should get a QR code tic-tac-toe sheet and a questions sheet. The teacher/ person in charge should keep the answers page to check their work.
Prizes are up to you! I'm going to take pictures of the winners and post them to my blog! (It's free and the kids get 5 minutes of fame!)
