DS is the only child in the district in his grade level who is subject accelerated for math. In fact, he will be the first child so far to be in 5th needing 6th grade math. I would actually have no problem logistically driving him to and from the middle school, I just am not sure how awkward that will be since the drive will take about 10 mins each way. It really wouldn't even be a problem if he missed stuff in 5th grade since he's ahead of the curriculum in general, he's just hoping to miss as little as possible of any specials or fieldtrips or other fun activities that would be inevitable.
MON, I, too, was thinking that it might be best for him to take a 6th grade class so that it was clear on his transcript that he'd completed it and no one could make him repeat it. For the last few years it's just been reported on his transcript as "he is doing well in X grade math," X being the grade up. This, I think, might be particularly important if he switches from the school system he's in now to the private one his siblings are in like we're thinking he might.
Haven't looked into Thinkwell - thanks for calling my attention to that, as well!
