I have a "competitive" management system in place in my classroom. Students are broken into groups each month, based on where they sit in the classroom. Students in each group work together to earn points as a group. The group at the end of the month who has earned the most points gets a reward of some kind, whether a prize, free time, etc. This sheet is used to record the points students earn each week. I keep it displayed on a bulletin board for students to see.
