It is based off individual work and team work within the classroom. Make sure that the sound is on and up for the kiddos to hear those "bling" that gives them the incentive and the cue "that the teacher is looking to give out points."
Make laminated posters to hang in the classroom. The document is editable so that you can add your touches for your classroom and student needs.
