The 6th grade has a group of mean girls that are driving me crazy. They are all in my homeroom and I know that they do not like me, which is fine. However, they have a lot of drama. In another class, they had their phone out, taking a snapchat of someone else, etc. They are sometimes rude to me by not listening. I had to write one student up for refusing to take off her hood. They consistently try to talk during math. One girl does not take notes in class and complains every day that she's confused when she doesn't try. Another student didn't take notes, so I told him that he has to copy the notes before I help him...to which he responded "Isn't a teacher supposed to help?" and I heard the girl say something about getting fired. When I raised my voice at the kids, she said "why are you yelling at us?" I feel like she doesn't cross the line to get a detention always but they are getting under my skin. How do you handle these types of "mean girls"? I feel bad that 2 girls seem to be influencing the behavior of the other kids.
