Comment We practice: Re:Less Is More (School != Day Care) (Score 1) 1514
Our children 10 and 12 home educate about 1 hour a day and that's all they need. No homework is needed (since we, ummm, home educate) while no excuse will get them off the hook (no fire alarm to pull, no disruptive questions to waste time, etc.).
I personally think 1 hour is too much but I allow my Japanese wife to do so since she's already out of her comfort zone (she is used to the Japanese way so she had to become unschooled at many levels to get to the current state).
When I asked them if they want to go to school, the youngest told me "no, because then the (short) recess is all that we would look forward to" (since they get on the average of 6+ hours of recess every day instead of 1 or 2 at a typical school and with no homeworks, they get even more recess time).
