You can use this form to track the student's behavior for the week. I keep it on my clipboard so it's easy for me to keep track of their behavior. If a student is using profanity on Monday, I'd place a P, if the same student is using profanity again I'd place another P under Monday. This helps me see how many times the student was being disruptive. You can edit the demerits as you please :) I use this form during conferences as well as for field trips (i.e. a student is consistently disrespectful and off task so they can't go on the trip). I also let students know when they are receiving a demerit and they usually fix their behavior.
Treasure chest, extra recess, and other incentives.
This is also great for team teaching. Pass the sheet to the next teacher so they can continue keeping track of those students. If a student is using the bathroom in every class then that might be a concern due to loss of learning time (or there might be a health issue, etc).
