My first grade class is extremely talkative. I have been very consitent with the rules on talking, but they continue to talk. When I am teaching the majority of the class blurts out about anything and everything, whenever they feel the urge. If someone makes a comment they disagree with or they feel they can elaborate on they blurt it out. It takes us 30 minutes to get through a 5 minute activity. I have a few students that are becoming frustrated because of the behavior. Other teachers that come in seem to have the same problem. I started the year teaching the class rules and procedures. I have been very consistent. It may just be one of those classes, but there has to be a way somehow to get this under control. Any suggestions?
