My elementary classes got points for the following:
1 pt. - coming in quietly and getting seated quickly for work - all eyes at me.
1 pt. - listening to instructions and asking appropriate questions - good discussion.
1 pt. - working quietly and on task
1 pt. - cleaning up on time (stopping when told to do so) - all helping
1 pt. - lining up to leave - good review of concepts - all hands to self.
Say the magic word: "Extra Credit"
Each student assigned a portfolio to keep their work in. This can be one piece of poster board folded in half and with the sides laced up. They decorate them with their name and class period plainly on one side. Each class can be a different color. This helps keep their portfolios from getting lost in the wrong class.
