This letter expresses, to the students, what comes of wasted time in class. This discussion explains to the students how wasting just a few minutes in classes has a major impact on the classes' learnings. I have used this writing in grades three and up. I have read it to the class as well as had the students read it aloud, students have written their own version of this "discussion of behavior." Students can also use this as bounce off for how they will improve behavior, both is discussion or written.
