How much homework should my child have? The 10-minute rule, grade by grade

A widely used guideline in US schools is the 10-minute rule: about 10 minutes of homework a night for each grade level. That works out to roughly 10 minutes in 1st grade, 20 in 2nd grade and 50 in 5th grade, with little or none in kindergarten. No law sets these numbers, so your district’s or your school’s homework policy is what actually applies to your child. When homework regularly takes much longer, tell the teacher.

Below: where the rule comes from, what it means grade by grade, how it compares with what parents report, and what to do when homework runs long.

What is the 10-minute rule for homework?

The rule is simple arithmetic. Multiply your child’s grade by 10 to get a reasonable number of minutes per night: a 3rd grader would have about 30 minutes, a 4th grader about 40.

It isn’t a federal standard or a law. The National Education Association (NEA), the country’s largest teachers’ union, published advice for teachers in 2020 noting that many districts follow a guideline of 10 minutes per grade level. The column calls it a good rule of thumb, one that can be adjusted for particular students or subjects.

The rule is also linked to Harris Cooper, a Duke University psychology professor who has led two large reviews of homework research. When the second one came out in 2006, Cooper said its findings were consistent with the 10-minute rule, which he described as the commonly accepted practice of adding 10 minutes of homework with each grade. The same review found that the link between homework and achievement was much stronger for students in grades 7 to 12 than for elementary school students. In other words, for young children, more homework is not a shortcut to better results.

How much homework by grade, from kindergarten to 5th grade

Here’s what the 10-minute rule gives for each grade, next to what parents reported in a federal survey.

The last column comes from the National Center for Education Statistics (NCES), part of the U.S. Department of Education. In its 2016 household survey, it asked parents how much time their child spent on homework outside school in a typical week. Children who had no homework count as zero in those averages.

Keep two things in mind when you compare the columns. The survey figures are parents’ estimates of a whole week, while the rule is about a single school night. Even so, the gap is large in the early grades: at 10 minutes a night, a 1st grader would do less than an hour of homework over a five-night week, while parents of 1st graders reported about four hours. If your child’s homework load feels heavier than the rule suggests, you’re not imagining it, and you’re not alone.

How much homework should a kindergartner have?

By the rule’s arithmetic, kindergarten comes out at zero. In practice, kindergarten homework, where there is any, is often light: reading a picture book together, a handful of sight words, some counting. If your kindergartner regularly comes home with more than 10 or 15 minutes of work a night, it’s reasonable to ask the teacher what’s expected and which parts matter most.

Does reading count as homework?

That depends on the school. Many elementary classrooms ask children to read every night, often for a set number of minutes and sometimes with a reading log to sign. Some teachers count that time as part of the homework; others treat it as separate.

Ask at the start of the year, or in a quick note. If reading is separate, the 10-minute budget covers everything else: the spelling list, the math facts, the worksheet. If reading is included, a 2nd grader with 20 minutes of reading has done most of the evening’s homework already.

Does my child have to do homework?

There’s no national homework law in the US. Decisions about homework are made locally, by districts, schools and individual teachers, and policies vary a lot. The NEA column mentions that some districts and teachers have dropped homework altogether, while other schools assign it every night.

If your child’s class assigns homework, it’s part of what the teacher expects, and skipping it quietly rarely helps anyone. But you can talk about the amount. Teachers can’t see what happens at your kitchen table, and the NEA column itself points out that parents know how their child works at home, which makes them a useful partner in deciding how much homework is right.

What if homework takes much longer than that?

A night that runs long now and then is normal. A pattern is worth looking into. Here’s a simple way to do it.

1. Time it for a week. Write down when your child starts and stops each night, and which task took longest. Count the time actually spent working, not the time spent arguing about starting.
2. Look for the cause. Is your child stuck on the content? Distracted by a screen or a sibling? Tired by 7 pm? Or is there simply too much?
3. Set a stopping point. Cooper’s advice for young students is that homework should be short and lead to success without much struggle. If your child has worked steadily for about the time the school expects and isn’t finished, stopping there is reasonable.
4. Send a short, factual note. For example: “Sam worked on the math page for 35 minutes tonight and finished half. The regrouping problems were the hard part.” That gives the teacher information they can use, without turning it into a complaint.

If the same thing happens week after week, ask for a quick conversation. The teacher may shorten the work, explain the part your child is missing, or tell you which tasks matter most.

How to keep homework within the guideline

• Pick a regular time. After a snack and some downtime, and well before bed. A predictable slot removes the nightly debate about when.
• Start with the task that needs the most focus. Most children have more attention at the start of a session than at the end.
• Put screens away. Yours included, if your child finds it hard to settle when you’re scrolling nearby.
• Keep practice short and focused. For things to learn, like a spelling list, math facts or a poem, ten focused minutes on most nights does more than a long session on Thursday.
• Protect bedtime. The CDC recommends 9 to 12 hours of sleep a day for children aged 6 to 12. If homework is pushing bedtime back, it’s taking too long, and that’s worth telling the teacher.

Where Kamelo fits in

Kamelo is an app for parents of children in kindergarten through 5th grade. You take a photo of tonight’s homework (the planner line, the spelling list, the math facts, a poem or a lesson), check what Kamelo read, and your child practices exactly that for about ten minutes with Kamelo, a small chameleon who changes color. There’s no timer by default, mistakes are an “almost” instead of a red mark, and Kamelo never does the homework for your child: the right answer only appears after your child has tried. It’s built to fit inside a short homework routine rather than add another task to it.

Kamelo is planned for the US in January 2027, on iPhone, iPad and Android.
