Quiet critters-when you decide it is important for students to be quiet pass out quiet critters- take them away from students who talk. At the end of the activity anyone who still has a quiet critter gets a prize, point, whatever you use. Brilliant!
Rewarding kids with things they get to do instead of things they get to have. When they do something good, they pick from the jar and get things like to stay up a little later or play outside a little longer etc. Cute idea!
