I have some children in my first grade classroom that absolutely refuse to follow my directions, throw tantrums, defy me, and show no respect whatsoever. Some of the children talk while I'm speaking and completely ignore or pretend not to hear me. I am apalled at this behavior and would have never thought of acting this way as a student. How can I gain the respect that I deserve in my classroom? I do use consequences for inappropriate behavior and rewards for good behavior, but sometimes this does not seem to work. Help!
