So I am an early kindergarten teacher and I started at my job last month teaching summer school. I have these two girls, I'll call them Jill and Jane. They were in my summer school class and now they're in my regular class. They were behaved ok during the summer. Now they gang up and run around the room, jump up on the mats scream and sing. During lessons on the carpet they kick their legs. They talk back to me. When I reprimand them they look at each other and laugh. I haven't found something that works with these girls and am looking for advice. I have been calling in another teacher to lecture them but I don't want to do that, I want to manage them myself. Any advice would be appreciated!!
