After thinking more about what I saw today, plus reflecting on our conversations, this is what I think is going on: there's a group of boys who are very athletic and whose friendships with each other have been cemented through team sports (which DS has no interest in). Plus, they are much more physically capable than he is, which affects how they play on the playground. These are the boys that DS would like to be friends with, but they don't have much interest in him (they aren't mean to him, as far as I can tell, they just like each other more than they like him). I think it's human nature to see rejection more clearly than he sees the warm feelings of the quieter boys in the class.
DS was enthusiastic about having a playdate with one of the quieter boys that he engaged with a lot during the field trip.
This sounds like my son to a T...except he is 6 and in first grade (summer birthday). He seems happy bu doesn't have a social group because he is not athletic or interested in sports and he is smaller and younger than most of his classmates. Academically, he is doing great in 1st grade so I'm not redshirting him because of social things. Working on it....we should get our sons together!
