This is a great way for students to show their behavior to their grownups everyday. It helps reinforce students that almost always have good behavior, and also helps students know if there is anything they can work on. I have my first graders fill in the face they think they earned at the end of each day. They then bring me their chart to check (it sounds like it would take a long time but it's really quick!) and I check any lines they can work on or write a note to their grownups.
