If you have a "treasure chest" or other prize system in your class

I was in BJs earlier and they had bags of 80 little cans of play-doh for $9.99. They are meant for trick or treating, but they had all the colors in there, not just black & orange. At the Levittown store they were near the end of a toy aisle, next to an end-cap with halloween costumes.

We usually give them out for trick or treating, in the past I've paid $4 for 20 cans so this is a good deal. My next door neighbor takes my extras to give out as rewards in her K class, so I thought I'd share here as well.
