It's only the third week of school and I'm already losing my patience with some kids. I have a small class, but you'd never guess it because some of them never stop talking. I have 3-4 kids who call out answers constantly. I give lots of positive praise for those who raise their hand, but I can already tell that some of them are going to start calling out their answers too as it's the only way for them to get a turn. I've also tried to ignore those who call out if they spoke when it wasn't their turn, but they just don't seem to care. They continue to shout whatever it is they have to say until somebody acknowledges them. I feel like my students aren't learning anything because we are constantly interrupted and I never get a chance to finish what I am trying to say. I don't know how to get them to stop and I'm afraid that it's only going to get worse as the year goes on. Please help me.
