Howler and squishys skirt a point that I'll make explicit: these kids learn so blazingly fast at this age that almost no un-personalized environment will be well-adapted to their interests or needs for long, socially or academically, so don't count on school to push him. (Not should it at this age, I'd argue!) Far better to let him find his own learning opportunities through play. Pleasure is the name of the game.

The academics simply can't be avoided. If our kids want to learn something and material so much as tangentially related to the topic of interest is within 1,000 miles, they'll learn it. Provide the material as requested, scaffold, and support.

I say this as the woman whose son spends 95% of his day smashing trucks together, and who read spontaneously before 2.

What is to give light must endure burning.
