Yes, find him peers - as many as possible!
My child started dumbing down instinctively to fit in and be liked. He faced a lot of hostility because he was perceived as being "different". So, we removed him from that educational environment and put him in a place where he has peers who can read at his level and have deep interest in math so that he has something common with them. We also put him in enrichment classes like Chess, robotics, music ensemble group etc where he meets kids who are far more advanced than him and where he can progress at his own pace and he does not feel like he needs to fake that he is not really capable. We have also started dipping our toes into the competition circuit and he was pleasantly surprised at how many smart kids turn up at all the local competitions.
