Behavior modifications, though effective, can sometimes be VERY time-consuming. Last year, a coworker had a very spirited child who needed a few modifications to make sure he stayed on track. We knew he LOVED tablet time so we made him a set of 6 puzzle pieces with a picture of a tablet on it. The idea was that he would earn puzzle pieces when he completed his work. Once the puzzle was completed, he was able to go play on the tablet. It worked SO well!
I made a set of incentive puzzles for behavior modification purposes and included a variety of incentives for the students.
