Are you sure? When I read a subset of commenters here, I'd swear it was 1017.
You have a funny viewpoint as to what comprises technology in classrooms. Also what comprises mathematics. Plenty of people who know more about teaching and plenty who know far more mathematics (and apparently who know more about programming) would and do disagree.
Rather than settle for being a mentor to your child (or albatross around his poor neck), you want to tell EVERYONE whose thinking and work diverge from yours that s/he is a fraud. That's simply unconscionable. But here in the shrunken universe of math-teach, you really aren't reaching many people at all, so have at it. You're certainly not about to hamstring the likes of Kirby Urner or his students, and they are getting a huge leg up on your son.
