DS is 12, in his first year at secondary school.
He's had a great start to secondary school, he seems to be doing really well and has made plenty of new friends.
However on and off he's been having problems with a girl at school. The first I heard about it was him telling me a few months ago that she'd been calling him Billy no mates on the bus ( as there wasn't any space near a friend), he brushed that off as it wasn't a biggy. Since then he's commented that she's hard work to be around.
We saw her when we were out one day and she spent a lot of time glaring at DS and his friend.
Last week there was an incident of talking in class, this girl is on DS's table and the whole table were given a number rather than a stamp in their planner ( stamp is a reward, number is there in the event of something being wrong). The girl has since started abit of a war against DS, whispering about him etc. The girl has now been moved off his table.
Yesterday DS came home annoyed and upset, they'd been designing something and the name he'd called his character sounded similar to the name of this girl ( but also made sense to call it that IYSWIM). The girl has now said she's going to report him and that basically he needs to stay out of her way or she'll cause trouble 
Subsequently DS didn't go to his homework club yesterday as he knew she'd be there and would also be on the same bus, meaning he's had to use his lunch break to do it today instead.
None of its major stuff I know, but I want to try and nip it in the bud. I've suggested to DS that he tries to avoid the girl ( without making it look nasty), and that maybe he should ask his tutor how best to deal with it?
Any ideas? I'm new to this secondary school lark!!!
