I am a new substitute and have subbed for 2nd and 3rd grass classes so far. I have several problems that I would loveee some advice on: 1. My biggest problem is that I CANNOT get them quiet. There is a constant chatter ALL the time, even when I am talking. I feel like I spend the whole day going "Shhhh ... shhhhh ... David, be quiet ... Sierra, I see you talking .... shhhh." And even when I tell a specific child to be quiet, 10 seconds later they are talking again! 2. As a sub I feel like I can't really "discipline," but what am I supposed to do when a kid does something mildly bad? E.g. One of my kids today repeatedly was acting out, annoying his neighbors, etc. 3. What I do about the constant tattle-taling? Thank you guys, any help would be appreciated.
