Pinner said, "Back to school night-- might be cheesy for middle school but who am I kidding lol". I'm thinking I could give a cute jar of mints to the teacher thanking him/her for his/her commit-mint, involve-mint etc. with my child!
This would make a great procedure (Harry Wong). Count to five or hold up one finger at a time when the class needs to refocus. Discuss what occurs for each number at the beginning of the school year and eventually the reaction will be automatic.
