Disrespectful Behaviors

    Just wondering if any of you have noticed a change in
    your students overall this year (or even the past couple
    years) in regards to disrespect. I have a class full of
    5 year-olds who think they are 15. They groan and roll
    their eyes at me, they tell me no, they are demanding. I
    am wondering if it is a fluke or if it is a sign of the
    times? I'm afraid it is a sign of the times, and it is
    really sad when you have a class full of young children
    who should enjoy singing, being silly, reading picture
    books, and learning! It is making for a not very fun
    year! Any tips or ideas would be great!
