I use this chart with students that have a difficult time completing work on time. I use it when my regular classroom management system isn't enough. If the student completes their work on time, they get to color a smiley face. If they do not finish their work on time, they do not get to color a smile. At the end of the day, the child totals up the smiley faces, and there is a place for a parent signature. This is good for documentation. You can look for patterns to see if there is a certain time of day that the child struggles to complete their work.
