Included here are three tools for managing an older grade level classroom. These tools make students accountable for their own actions and worked wonders when I taught in an inner-city middle school.
Hand out the "rights, responsibilities, and consequences" sheet at the beginning of the year and review thoroughly. The "behavior reflection" sheet gets handed out as needed and the "weekly behavior report" gets filled out weekly for each student. The weekly behavior report might seem like a lot of work, but it really makes a difference in the overall community feel of the classroom.
