Good Behavior for the Substitute!

Thoughts of a Third Grade Teacher is hosting a linky party for help with the substitute!
One thing I started is a behavior incentive that I use every day but it has an extra incentive when I'm gone.  I saw this idea somewhere on the web but I have no idea where.  I have a 100 grid and I have put stickers on five spots.  Like having free spots on a bingo board.  The class earns stickers for doing certain things.
1 sticker = walk quietly in the hall
2 stickers = work quietly during rounds in daily 5
2 stickers = quiet in the bathrooms
3 stickers = a teacher tells me what a great class they are
(this could be a specials teacher or anyone who comments as we walk by)
4 stickers = principal or administrator tells us we are well behaved
4 stickers = THE SUB TELLS ME IN A NOTE THAT THEY WERE WELL BEHAVED!
4 stickers =  Well behaved at an assembly.

When they get 10 stickers in a row they earn a class prize.  I've given candy, extra recess, we played games and much more.

Have Fun!
