Need an incentive to get your kids cleaned up in a timely manner? I have created a motivating graph. Each time you ask your class to pick up their area, just tell them you're doing a spot check. If they have passed the "test" you can fill in the graph or put a sticker in the row to keep track of their successes. I am a specials teacher, so I have a column for all 21 of my classes. At the bottom, I write in the teacher's name. If you are a classroom teacher, this would work for you as well, you could type in the subject area. I post this outside my classroom on a bulletin board so each class can compare their graph to others.
