I have 4 students that I think would benefit from a behavior management system in which they received a sticker every 30 minutes if they behaved appropriately, and then they got a prize at the end of the day if they had enough/all (I have't decided) of their stickers. However, I don't want to use this for my whole class. I currently use a stoplight type system which is effective for the rest of the class. Is it possible to have a different behavior management system for 4 students? How would I make the rest of the class feel like they were treated fairly?
