My daughter is in K and is always talking about clubs. I keep asking her if she includes everyone if the boys are allowed to play in their club, etc. I would just keep talking to her about how it would feel to be left out and what she can do to be nice to this girl even when the others aren't. Role play some things she can say to the other 3 girls when they are playing to include the other girl. I found out in my DD's K class is that one girl was being "left out" of at their after care program at school (my DD does not attend this). I was also surprised because the way my DD talks they all get along well. I've also hear that with girls when there is an odd number someone always ends up getting left out because the girls tend to pair up... not sure if there is a way to deal with this. We have lots of dinner conversations about things like this. I'm going to check out that book too.
