Make a calendar each month with all of the major activities listed. Make copies for the whole class. Include weekly themes/topics, deadlines for projects, test dates, etc. Your students will know what to expect this way, and you shouldn't get as many questions about scheduling. They will also be more responsible in turning in projects and studying for tests since they will have no excuse for not knowing about them. They can also write their daily homework in the extra space. It will help everyone to be more organized.
