I've been scrolling back through some of the pages and it seems that everyone thinks the best solution for behavior issues is prevention, distraction, and positive reinforcement. I'm wondering what your opinion is on something like this for 4 year olds: Have an incentive sticker chart. When they're caught doing something good (such as listening well during a lesson, playing nicely, etc.), they get a sticker on their charts. When a student's chart is full, he/she gets a prize from a prize box. I feel like Pre-K might be too young to do the flip-your-card-to-another-color-and-get-a-consequence thing, so I'm wondering if this method would work more.
