Stop telling your students what the computer rules are. Instead, have them discover them using QR Codes. This activity will have you display the enclosed QR Codes all around the room and have students scan them and write them down. Now, each student will have the class rules written in his/her own handwriting! No more saying, "I didn't know that was a rule!" You can show them the rule written in his/her own handwriting!! You can use it the first day of school!
