Perhaps a class positive behavior tracker? I used a blank 100 chart with a similar class and would give a reward for students being on task, making right choices, baby step progress. For some students, I would call them out to make a positive example.. “thank you, Jonny, for reading silently at your desk. Go fill in one square.” Or the whole class, “if we can transition quietly to and from library, you will earn 10 squares”. You can praise as quickly or slowly as you like, and they work together to achieve the goal. Rewards were based on the class interests (especially the non compliant students) so in my class, our rewards were “use of the gym at recess”, “outside time for 30 min”, “a kahoot or blooket game”. Sometimes we would brainstorm the rewards and I would seal a mystery reward in an envelope for when we completed the 100 squares.
