You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up.

That word diligently, in the Hebrew is shanan. It means to point, to pierce, to inculcate. Inculcate means teach and impress repeatedly. One time, ain't gonna do it. Repetition.

And everywhere...at home, on the way somewhere, going to bed, getting up.

To me, there is no better way of fulfilling this command, than to home educate.
