Reinforcers (rewards): I like to use as many natural reinforces as possible, and find reinforcers that are reinforcing. The main things that I find myself using (and the students asking for) are:
a) Detention passes. Four equal a Saturday school pass. They can use them for any
teacher's detention. b) Late passes. This is something they can use to not get a tardy from me, or have me write a note for another teacher.
c) Phone Call Home. Students sometimes like this so their parents hook them up with a little sumpin sumpin.
d) Free Time. 15 minutes usually.
I have this little sheet that has a list of these things and the student can pick which one they want. I put their name on it when they get a pass, and I also put the date and try to use colors and what not.
