This is a format I have used with my students and it has really helped keep track of behavior issues in the classroom.
The student writes a letter home to his or her parents following the directions at the top of the letter. Then the student must take it home and return the next day with his or her parents' signatures. If they return without the letter, a consequence is given until they return the letter.
After the letter is returned, I put it in that student's communication file so I have proof.
