In some of my classes I offer what I call "Coolness Points". At the end of each designated period, individuals that have earned a minimum number of points get a reward!
Below is an explanation of how Coolness Points can be earned and lost.
How to Earn Points:
Win games: Points are awarded for certain in-class activities, such as Chaboonary. Often these activities are done as groups. In this case, each member of a group will earn the same number of points for that day.
Find mistakes: Each time you identify an error on Blackboard, a test, etc. you earn 5 points.
How to Lose Points:
Be late / absent: Each absence causes you to lose 10 points. (Two tardies count as an absence.)
Misbehave: Any infringement on the "This class is rated PG" policy, or any other disruptive behavior will result in the loss of points (the amount to be lost will depend on the severity of the infringement.)
*Note: Even though your grades can influence your Coolness Points, your Coolness Points never affect your grades.
