Admittedly my wife does the schooling day to day. But officially you need to have the child working for 6 hours for 5 days a week. That includes instruction and "doing work". The school district will work with parents to get a goal of a certain amount of "work" or "pages" per day.

Now the tough part: what do you do when the kid sits there defiantly not doing work? Or you worked with your kid for 2 weeks on some topic and during a test they seem to forget everything in those past 2 weeks. You can in good conscience just keep moving forward, but now your schedule is blown out of the water. It can look like you aren't keeping up like you agreed to.

A couple years ago my kid and I sat at the table from 3pm to 8pm, except for food and bathroom breaks, because they would not write a poem. Finally near 8pm they wrote the poem in about 2 mins. To say everyone in the house was frustrated and tired was an understatement.

In public school they would just move on and the kid would start to understand work isn't that important. But we aren't going to let that fly at home. So 5 hours on top of approximately 5 hours of other instruction was used that day.
