How many hours a day to homeschool, by age

Less than you think. A school day is six or seven hours, but a lot of that is lining up, waiting, moving between rooms, and one teacher working through a whole room of kids. At home, with one teacher and one to three kids, the focused part of the day is much shorter.

Here's the rough guide I'd give a friend. Treat it as a starting point, not a rule:

• Pre-K and kindergarten need 30 minutes to an hour of anything that looks like a lesson, in short pieces. The rest is play, books, and being outside.
• Grades 1 to 3 take about one to two hours, and reading and math fill most of that.
• Grades 4 to 6 take two to three hours, as kids start working more on their own.
• Grades 7 and 8 take three to four hours.
• High school takes four hours or more, since credits and harder material need real time.

That's time on schoolwork. Reading a novel on the couch, a museum trip, baking with fractions, and an hour of drawing count as learning too, and they don't have to fit inside those numbers.

Why it takes so much less time at home

Think about a spelling test in a classroom. The teacher reads twenty words, waits for the slowest writer, collects the papers, and grades them tonight. At the kitchen table, your kid spells the twenty words, you see which three they missed, and you practice those three. Ten minutes, and you know more than the classroom teacher will know until tomorrow.

That's the whole reason. There's no waiting for anyone else, and you notice right away when something clicks or doesn't.

Some states set a number

A few states require a number of days, or hours, of instruction a year. If yours does, look up exactly how it defines instruction, because it's often broader than sitting at a desk. Check your state's rules and keep a simple log if they ask for one.

When the day keeps running long

You've probably had the day that should have taken two hours and took five. Math started at nine and was still open at noon because every problem turned into a negotiation. It's common, and it's rarely about the math.

Usually one of these is going on:

• the lesson is at the wrong level, too hard or too easy;
• everything is happening at the table, with no break between subjects;
• there's more on the list than any kid could get through;
• it's 11:30 and nobody has eaten since breakfast.

Try cutting the list before you add time. Do the hardest subject first, while everyone's fresh. Set a timer for twenty minutes and stop when it rings, even mid-page. A kid who knows math ends at 9:20 will work very differently from one who thinks it might go on forever.

A short day is fine

It can feel like cheating when everything's done by lunch. It isn't. Your kid gets the afternoon to build something, read something they chose, or be bored long enough to think of something to do. That time is one of the best reasons to homeschool.

If the work is done and they understood it, the day is done.
