Thanks for your reply. He's always been interested in number patterns more so than calculations. When he learned to count (by 2yrs) he quickly started counting by 10s, and then other, less regular intervals. He picked up multiplication easily around 3, but was more interested in squares/ square roots and prime sequences. His interest now seems to be in probability -- he's a fan of Nate Silver of fivethirtyeight.com and sabermetrics both for sports and politics. We tried to get him to go to a camp last summer on this topic, but he didn't want to do a sleep away camp for that long. He's also a geography whiz and frequently complains about "having to write essays when it could be explained with maps and charts". He is taking AP Human Geography next year as well as sports history, both of which he's excited about.
I don't know whether there's an option to skip Algebra 2 -- I don't remember it enough to know if there are critical topics he needs to do well in trig/precalculus, or if he'd balk at skipping- - although most of his friends were in Algebra 1 this year so he'd not be with his friends anyway for math.
