This simple stamp sheet 10-frame is what I use in my elementary art classroom to encourage and reward positive behaviors.
Students receive stamps when they exhibit certain behaviors (see: How To Earn a Stamp resource). Then either I, or a student stamper will give a stamp in their 10-frame. When the stamp sheet is full, students get to choose a simple reward (see Stamp Sheet Rewards).
This is the fastest and easiest way I have found to encourage positive behaviors for each and every one of my 650+ elementary art students--I hope it works for you too!
