Have you considered having your students track their clip chart progress each day? This behavior calendar is an easy way to record daily clip chart colors that can be shown to parents daily, weekly, or even presented to them at conference time.
Simply have students record their clip chart color at the end of each day by writing or coloring it in. Parents can initial weekly to show they are aware of their child's classroom behavior patterns. The "Parent/Teacher Comments" page can be printed on the back of each month to allow for additional communication about student behaviors.
This calendar is not year-specific. Teachers can write in the days of the month before copying or they can let students do it on their own. The grayscale color scheme makes copying class sets simple.
