I started teaching high school last year, and was given several ideas for dealing with classroom behavior. I posted them on my TPT for free. They is a behavior reflection worksheet and a student behavior contract. I used both of them with high school students. I don’t think it really gets students to think that hard on the behavior. I really used it to document their behavior. The students would write it down and then I would have a copy if I needed to address things with parents or administration. Save a teacher time from having to do the documenting. Feel free to check them out. Free to download.
For elementary school I posted art bucks that can be used for rewards.
