My co-teachers and I have a student of the week. It works very well with us. What you do is keep track of student behavior however you want (chart, tickets, etc.). At the end of the week, the student with the most points, or least points depending on whether you keep track of positive behavior or negative behavior, gets to be the "Student of the Week" the following week. A note is sent home with the child on Friday stating that they may bring a picture or stuffed animal from home to put on their "Student of the Week" desk. The special desk is decorated and is in a special place in the room. The student also gets to wear a "medal" (you can find these pretty cheap at Oriental Trading)for the week so the other students and teachers in the school can recognize their good behavior.
