Professional collaboration was at play two weeks ago when I went to my fellow teacher (and sister-in-law) Christe Montgomery to ask for ideas for building community and managing behavior. She suggested the Ron Clark Academy house system that her school implements. It sounded fun and engaging, so I rallied the troops in 4th grade and we went for it. It was a hit very quickly. The house system teaches teamwork, responsibility, teamwork, friendship, and leadership.
