What I've learned is that the most important part of a good classroom management plan is consistency and high expectations. Helping children learn to respect themselves and respect one another is huge. And LOTS of praise goes a long way!
We have a school-wide plan since we follow PBIS. We have tickets called Pride Paws that students can earn when they are making good choices. Every 2 weeks we spend time trading them in for small prizes or extra privileges (recess, computer time, sit with a friend at lunch, etc).
I used a behavior clip chart last year, but this year we have implemented the behavior stick school-wide. It's just like a chart, but in mobile stick form. :) It goes with us everywhere... to lunch, specials, etc.
