Use these forms to promote good behavior. Write a students name of on the slip, put it away in a special place and tell the students you are watching a "Secret Student". At the end of the day, if that student was well behaved you reveal them and they get the slip and a prize from the prize box! If they weren't, you don't reveal the name you just remind the students to always be on their best behavior in case they are the secret student!
