After 21 years of teaching, I have come up with a few little tricks. One of my favorite is how to get my carpet from this:
to this in less than 2 minutes:
Simple! Magic piece of paper. All I do is choose a piece of paper, tell the kids go, and whoever picks it up gets a Magic Bean (a jelly belly). Simple and works EVERY time. On a management note, at first the kids will run up to you and ask if they have the magic piece. I won't tell them yes or no. I never tell what the piece of paper is until ALL the paper/garbage is picked up. Works great every time.
