To track homework and classroom behavior, many teachers use a system where students move their name card up or down a chart, and each level has an assigned meaning. This may range from warning to missing recess, or may even involve a trip to the principal's office. This gives students a visual of what the consequences when they break a class rule. If you want something more concrete to show parents at conference time, establish an "Oops" book. Use a notebook and set up a page for each student in the class. If a student forgets homework or breaks another class rule, he will write it down in the "Oops" book. On their page, they can write the date and the transgression. You may even ask them to write what they could have done differently so that it does not happen again. This way, students have to put some thought into what they did, and you have a better record of behavior patterns to share with parents.
How you manage your classroom directly effects how your students learn. Staying organized and establishing positive routines will leave you more time to teach.
