This struck a chord with me. Personally the question about math acceleration boils down to what is the end state of the process? Getting through the calculus sequence more quickly than what is possible in school doesn't seem to be worth the effort unless at the end of the road, my son wants to go farther that that in math. But at 7, its really hard right now gauging intensity and interest. While he has an aptitude and we've been doing 15 minutes before school because I have the time and he he seems to enjoy the challenge I can't tell yet if we're in for the long haul or if I should let him fall back to his in school sequence which is already accelerated.
