Pass out a piece of candy (I get the dollar bags from WalMart) to EVERY student and tell them that they are going to play the Super Silence Game. They may NOT eat their piece of candy until they get home.
The rules for the kids are quite simple:
1. Stay quiet.
2. Look for students who are talking. If you (the student) catch someone, you (the student) get to take the talking student's candy. (depending on your children you may not want to give them the power of taking other kid's candy)
That's it. It's another one of those games, like Kings and Queens, that you think won't work, but you'll be pleasantly surprised! You can read aloud, have them do silent work, have them clean the room, pack up...whatever! It only works about 20-30 minutes, so don't abuse it. They will even walk quietly down the hallway on the way out. Golden!
