This was my 2nd week in a kindergarten class. I haven't set up my class Behavior chart or anything like that because I haven't made it. I just haven't had time. My student's aren't listening to me at all, they're all fidgety. About 3 of them, one of which has been diagnosed with ADHD and is on medication, the other two show signs of ADHD. These three boys will spin like tops on the floor. They'll lay down on the rug some of them will get up and wander the classroom as I talk. They all talk out of turn and will call out answers. They're all loud during center time. They're basically all running amuck! One of the boys that shows signs of ADHD tried to stick his finger in the pencil sharpener and keeps sticking his fingers in the printer. I keep telling him not to do it. I have talked to the mother and she doesn't know how to help him. She says she can't be strict with him. She looks really young. The previous teacher that had him says she lost her voice because she always "yelled" at him. I haven't "yelled" at him, but talk to him sternly. When he does things that he shouldn't he gets time out or I take recess time away from him, but that doesn't seem to help. Any suggestions? During math time, I do it as a group and explain what they have to do. When they go back to their seats about 10 of them come back to me to tell me that they don't know what to do. So, I have to re-explain to them what they have to do. I find myself repeating and re-repeating myself during math lessons. Is there anything I can do to remedy this?
