If you are teaching students about dental hygiene check out this site for free charts to remind kids to brush their teeth morning and night. It looks like it will be very easy to print a personalized chart for each student. I don't know about you, but I love charts. It must be a teacher thing or just a parent thing. We used charts for potty training, for behavior, etc with my daughter. If I had only one class instead of 29, I'd use charts even more in my classroom too.
