I actually have a great class except for the fact that they bicker with each other over ridiculous things..."My pencil is taller than yours! No it's not! Yes it is"....or...."I was the first one at the rug! No I was first!"....and my favorite...."I was playing with that! You have more blocks than me!" Just stupid stuff. I try to let them solve problems like this on their own and I have modeled kind behavior but it's gotten bad. They argue like brothers and sisters. It's almost like they are sick of each other. I have a very small class. I hate to have them give me a star (our behavior system, they start out with three at the beginning of the day) for such small things. But, they're driving me crazy!! Any suggestions?
