Remember that at that age they want to be treated like adults one minute and like kids the next. But as much as it seems like they want you to be their friend, remember they really just want you to be friendly to them.
I wish teachers would remember that kids want to be shown respect - for their ideas, their thoughts, their individuality and most of all, their feelings. (It'll make your life easier too, because with these behaviors comes mutual respect - and this goes a long way in a classroom of hormonal teens.)
Remember to talk to them rather than at them.
Oh, and remember its ok to admit that you don't know everything, and that some of them may know more than you and that you too make mistakes.
Good luck!
I love teaching and that age is one of the most difficult as well as most rewarding because there is such change in those year, both emotionally and physically and intellectually.
