I'm looking to change the reward system we have in class (I inherited it) we have 7 stars the children must earn to choose an activity. But any wrong doing results in a lost star that can never be regained. So if first lesson goes badly for one of them then theres no incentive to earn any more stars! I think it's a little harsh too- think I'd struggle to be perfect for the entire day everyday or by judged!
What systems do you have in place? We do have SEND children too.
