Send them to Private schools. Homeschooling will barely teach them what they need to know.
I agree that a good private school is the best alternative to the rancid government schools, but that can be an expensive proposition for many people. And with the Democrat Party in the pockets of the greedy teachers unions, it doesn't look like there will be any relief (ie., vouchers) for caring parents anytime soon.
Homeschooling is the next best alternative.
