popsicle sticks
I have a box of colored popsicle sticks ($1 for 200 at the Dollar Tree). I write an incentive on about 20 of them , but most are blank. The incentives include: science video, social studies video (which I planned on showing anyway), get ready for lunch early (so we beat the rush!), show and tell time, write with colored pencils for a day, extra read aloud time, dance party (which is actually just one or two songs long), bring a stuffed animal to school, etc. If I choose an incentive stick, we get to do that activity within a week. If it is a blank stick, we put the stick in a baggie, and when we get 20 blank sticks we will have 15 minutes of free choice. Right now I pick one stick at noon and one at the end of the day for great class behavior. I also choose one child (by picking numbers) after end of the day clean-up to choose a stick. That student tells what they did to help clean up, we all clap, and they get to pick a stick. I have had fantastic behavior with this. I'd be interested to know if it works for you.
