How do you handle classroom discipline?

The key way to handling classroom discipline is to:

• Make sure that you know where the student is getting when they make rude comments.
• Try and be fair to them, but if they're not giving back to you what you are giving to them, then it's time to be making notes to the Principle.
• And finally just relax, because if the students see that you're looking intense all the time, they'll want to push one last button for you to shout at them.
