Star sheets have been used to help keep track of student behavior. This is kept in the student’s desk as to keep it more private. Students get to color in a star when they are given an “at’a boy” and erases a star when they make a not so smart choice. I have students use a regular pencil to make this easier. There are 2 types of star sheet, one that has 30 stars and one that has 20 stars. I included 7 types of kids in black and white and 7 types of kids in color of each star sheet.
