Most teachers have a discipline system set up where there are rules and consequences. Often, we will reprimand the student and have them "turn their card over" or "change their card color," etc. but then find that we don't have time to follow through with the "consequences." It is very important to be consistent with your discipline plan, whatever it may be. Students will know that you won't be serious, and your plan might ultimately fail. The consequence that is most often neglected is one involving a note home to parents. In order to help maintain your discipline plan, have notes ready (within easy reach) so that you may simply fill them out and send them home with the student. You may want to print these notes on colored paper (brown works well!) and call them by their name, i.e. "brown notes." This seems to be especially effective for younger students.
