I got this one from working with Mr. Kantor last year. He called it the Blurt Box. It is used in class with students are talking when I am giving instruction or when another person 'has the floor'. We are on PBIS and because of this the specialists are asked to 'rate' the class at the end. I tell my older groups (3-5) they can get 5 blurts before they move to a 2 (or yellow). The littles (k-2) have 10 chances. They are a lot more chatty, as you know if you work the elementary. So far, I've been using this for a month and a half... and it's going well.
