These numbers are correlated with expectations in the classroom. When students break a rule they are given a number for that rule. I use it in addition to my classroom economy. Giving numbers for specific rules make it easier to document specific instances, communicate with parents, and keep documentation for the year. I keep a class roster on a clip board, and I am able to quickly write down their number. Then weekly I prepare reports to be sent home to parents explaining their behavior for the week.
