I was a homeschooling parent and was, briefly, on the board of directors and the lead mod for an educational organization because of it.
Most people overestimate how much work they need to put into homeschooling. They think they need to teach their kids like eight hours a day because that's how long they are in school usually and they feel overwhelmed.
This is not true.
One article I read years ago indicated that after standing in line, changing classes, doing lunch, having roll call, etc was accounted for, students in public school spent between one and three hours a day on actual learning.
Similarly, under California law (back in the day), one legal option for homeschooling was to hire a tutor for three hours a day. Not eight. Just three.
Public school teachers typically deal with classes of twenty or more students. Homeschooling parents have a much better student-teacher ratio and the one-on-one teaching is much more intensive than public school education.
You and your children will both experience rapid burnout if you try to spend eight hours a day actively teaching them. You don't need to and you really shouldn't. It's an unsustainable pace.
