<p>You feed the hungry child, whether that hunger is physical or intellectual. </p>
<p>Math is one of the areas where kids can eat as much as they like. The young math fiend may end up in math and may end up in a completely different field. But there are lots of examples out there to follow. The mathematically precocious child is more common than one might think.</p>
<p>I would move him towards AoPS, particularly the free resources like Alcumus. He’ll be ready for class sooner than you think, particularly since class participation (fast typing) is less important than doing the problem sets, which is done off-line. It’s really OK to just sit back and watch the information flow. Don’t be afraid to “repeat” classes. AoPS is at a completely different level from EPGY.</p>
