What's Your Number?

This is a strategy from the STAR Course (Successful Teaching Thru Acceptance of Responsibility - Performance Learning Systems)
Remember when you were a kid and your rode in the backseat of your parent's car with your brother (in my case), and of course, the two of us were arguing/fighting like cats and dogs. "He touched my side!" Well, the question is how many times did your Mom or Dad turn back to you and say, "If you guys don't stop this, I'm going to stop this car and ..." So, how many time before they actually did something?
For Teachers this IS a reality every day.  WHAT IS YOUR NUMBER? How many time do you warn in an unacceptable situation, before you take action and render a consequence? That's your number. Research says that your number should be ONE, two is OK, but ONE is most effective.
We invite your comments, question and discussion. Think about it! What is YOUR number, and How do you feel about that?
