I have a few general expectations each and every day. Some go without saying, for most students. However, a quick visual on my basic 'wants' helps my students focus and understand their boundaries with me. I want my middle school / high school students, who see many teachers in a day's time, to have visual reminders upon entering my room.
I sliced these reminders (2/page) in half and backed with colorful scrapbook paper before posting them down the side of my white board that they see each and every day.
Quick and easy!
