Daughter (7) admits she doesn't have many people to play with at school. What can I do help?

My daughter has always been very shy, top of the class and, I assumed, plenty of social interaction with friends. Over the past year or so she speaks less of her friends she met in nursery and more of a few others but last week she said she didn't have anyone to play with. We do have kids on our street and young family members she happily plays with.I know she struggles with new people or just playing with anyone like other kids would but didn't know she felt like this. We moved house not long ago and she begged us not to swap her school but now she said she wouldn't mind it...which seems unlike her.Few things I have considered, but wanted other people opinion on:Talking to the teacher, see what she thinks.Too much technology? We have an iPad and Nintendo, PC the works. While we're usually pretty cautious about her playing games she will always prefer go out. I work in the video game industry so it's hard to avoid but would reducing time sat behind a screen help her socially?Letting her play out on her own? We don't let her play out often, when she does she doesn't go out of sight. She still seems young to me but I was out at a younger age when I was a kid.As I said she is a clever kid more into books and crafts sort of thing than imaginary play or sports. I think this might have something to do with it as her hobbies aren't what the stereotypical kids are. I also feel like a lot of the other kids are quite old for their age.Thanks via /r/Parenting https://ift.tt/2H7x2vA
