Academically, subject acceleration, ability grouping, and the IB inquiry-based learning approach is working for the time being; I feel that if he can continue to have two or three other real peers around him, on top of the many other "bright" kids in his grade, he stands a great chance of having a happier elementary school experience than mine was. He's sad that his BF is moving, and I am too.
I agree with you assessment of the situation. You are headed in the right direction. You have the right map, and you know how to take your bearings. I hope that the other kids 'blossom' a bit over the summer - they may! Or a new 'at his level' kid may move to town soon. You'll have to see how it unfolds. I agree that 'real peers' are just as important as what the teacher is up to - well, maybe 'almost as important, but still very important.'
As for you, I am sad that this family is leaving. It's really key for you to step up to the plate and take responsibility for your own social life independently from your child. This is no small order! Parenting is exhausting and time consuming and hanging with one's kids friends is a time-honored way to deal with the stress. Yet again, it's one of those things where Gifted Parents have to work twice as hard to get the same result. I remember when my son was about 8, I realized that I preferred his company to any local adult! It struck me how uncool that was soon going to be. So I started dragging my attention away in small bits and strengthening my ties with adults who could adjust to the 'new me' and combing the local town for ways to hope to meet some adult females who I could enjoy without the filter, or at least in one specific area, and strengthening the cyber/distance friendships. That's why I'm so excited about upcoming conferences, such as BIQ next weekend. I got lucky and met my BFF about a year later - and now she's moving about 3hours away! So I do feel your pain.
As for helping your DS6, it might be good if you can find a fictional world for him to inhabit for a while right before and after the move, preferably one with lots and lots of volumes. And one where you can inhabit it with him. Sniff around and see what hasn't been read yet. Maybe the other family can read it too and you can do a book club over skype. I like Eragon, because I read the dragon as a mother figure who 'hunts for her own food(emotional support.)' I can't speak for the sequels, as my DS had no interest.
((pout)) and more ((pout))
