Mine is at school, not riding the bus. There's about an hour between waking and leaving for school, then four hours between school and bed. 2 1/2 of those hours are taken up with getting ready for school or bed or eating, so 2 1/2 hours a day free on a weekday, then all day Saturday and Sunday. They get some free time at school (it's kindergarten) about 1 1/2 hours a day.
About the same for my six-year-old, except she does gymnastics and dance class (two hours per week total). She walks 50 feet from school to dance class, and gymnastics is two blocks from school, so no time is lost to driving (this is deliberate on our part).
Oh, homework time is minimal.
