I believe I have that book actually! I haven't read much of it yet so that will definitely be on my to-do list! Thank you!
I am in a middle school and we are using a card system; Yellow (warning), Orange (warning) and Red (consequence) with a clear poster written in kids speak with the behaviors that we are asking for. The incentive to not get a Red Card is No Red Card Friday. Every other Friday, the science and social studies (non-tested subjects) teachers provide a fun activity for the kids that did not earn a Red Card. This model helps emphasize and reward the kids who make good choices and give the other students another chance to improve next week. The Red Cards are accumulate over the semester with escalating consequences.
A book that I enjoyed for quick, down and dirty tricks of the trade was Teach Like a Champion.
