Our school has implemented new parking requirements this year. To help promote the rules, I made these tickets for the administration to place on the students' cars that were following the rules. This was a great way to reward the students that were doing what they were supposed to be doing, as opposed to just providing negative reinforcement to the students that weren't following the rules.
Students turned in the tickets the following day and were rewarded with a treat.
I am planning on changing the wording on the tickets to use for positive behavior in my classroom as well.
