How to end math homework fights

Math homework fights tend to start when a child is stuck and an adult starts teaching. Make your job smaller: see that the homework gets done, help with one step at a time, set a time limit, and send unfinished work back with an honest note.

You may recognize this. It is twenty past six. The worksheet has been on the table for half an hour and question 3 is still blank. You lean over and say, kindly, "Look, it's easy, you just carry the one." Your child says that is not how the teacher does it. You show them anyway. The pencil goes down. Somebody mentions screen time, and now nobody is doing any math at all.

If that is your house, you are not doing anything unusual, and your child is not lazy. The evening goes wrong for reasons that can be named, and the fixes are small enough to try tonight.

Why does math homework blow up?

Math homework usually blows up because the child is stuck, not because they are unwilling. Math answers are plainly right or wrong, so being stuck feels like failing in front of the person whose opinion matters most. Add a tired child, a tired parent and two different methods, and a small problem turns into a fight.

• Being stuck looks like refusing. Staring, sharpening pencils, needing the bathroom and "I can't do it" are all ways of not saying "I do not know how to start".
• The method is not yours. Your way is quick and familiar to you. To your child it is a second method arriving before the first one has settled.
• The correction comes too fast. "No" from a parent lands harder than a cross from a teacher.
• It has gone on too long. After a point, more time at the table produces guesses and tears, not learning.

What is my job at the homework table?

Your job is to see that the homework gets done, not to teach the lesson. Set the time and the place, sit nearby, help your child get unstuck one step at a time, and tell the teacher honestly how it went. Teaching the method is the school's job.

Jason Zimba, a lead writer of the US Common Core math standards, told Education Week that the most important rule for a parent is to make sure homework gets done, and that "the math instruction on the part of parents should be low."

A smaller job is easier to do calmly. You no longer have to win an argument about methods. You have to notice where your child is stuck, and decide when enough is enough.

Does helping more make it better?

Not always. One large review of research found that parents' general involvement in schooling goes with slightly better results, while help with homework in particular goes with slightly lower ones. That finding cannot show cause, and there is an obvious reason for it: children who struggle get more help.

The review, published in Psychological Bulletin in 2019, pooled 448 studies covering 480,830 families. It is a correlation, so it does not tell you that your help is harming your child. What it does suggest is that the amount of help is not the thing to increase. The kind of help is what you can change.

A second finding is worth knowing if math makes you tense. One study of 438 first and second graders found that children of math-anxious parents learned less math over the year and became more anxious about it themselves, but only when those parents helped often with math homework. This too is a link and not proof of cause. Still, if you feel your shoulders rise when the worksheet comes out, a smaller, more structured role is a kindness to both of you.

What should I say, and what should I not say?

Say things that point at the work and can be acted on. Avoid anything that judges the child, compares today with yesterday, or tells them a question is easy. If it were easy for them, they would have done it.

The one to remember: ask "where did it go wrong?" before you say what is wrong. A US federal practice guide for teaching children who struggle with math advises questions that help children "self-identify where their thinking went wrong". A child who finds their own mistake has nothing to defend.

How do I help without doing it for them?

Help with the next step only, then hand the pencil back. Find out exactly where your child is stuck, do or prompt that single step, and let them carry on. If you are still holding the pencil at the end of the question, the homework is yours and not theirs.

Here is what "one step, not the question" looks like on a column addition. You fill in the ones and stop:

      1
    3 6 4
  + 2 7 8
  -------
        2

How long should math homework take?

There is no official number for math alone. The best known rule of thumb, from homework researcher Harris Cooper of Duke University, is about 10 minutes a night per grade for all homework together. By that rule a fourth-grader, the age of a Year 5 pupil in England, has around 40 minutes in total.

Cooper's rule comes from his review of US homework studies, and it is a guide, not a law. In Duke's account of the review he also says that "younger children are less able than older children to tune out distractions in their environment", which is a good argument for a quiet table and a short session. If your school sets its own expected time, use that.

Whatever the number, agree it before you start and say it out loud. A child who knows when it ends can spend their effort on the work.

When should I stop and write a note to the teacher?

Stop when the agreed time is up, when your child has tried the same step twice with help and it still will not go, or when they are crying or guessing. None of those improve with ten more minutes. These stopping points are our suggestion, not a research finding. Then write two honest lines to the teacher.

A useful note says how long you spent, what your child did alone, and exactly where it stopped. For example:

We spent 25 minutes on this. Questions 1 to 6 are all their own work. We got stuck on borrowing from a zero in 7 to 10 and stopped there. Could you go over it again in class?

That note does more for your child than four forced answers. It tells the teacher something a tidy page hides, and it shows your child that being stuck is a thing you report, not a thing you get in trouble for. If notes like this become weekly, ask for a short conversation.

A routine that takes the heat out

Do math homework at the same time and in the same place each day, after a snack, with the time limit agreed first. Start by having your child tell you what the sheet is asking. Stay close but busy with something of your own. End on a question they got right.

• Same time, same table. The argument about when to start goes away once the answer never changes.
• Start with their explanation. "Tell me what this page wants you to do" shows you in one minute whether tonight will be smooth.
• Nearby, not hovering. Peel vegetables, answer email. Be available for a stuck step without watching every digit.

Where Plusy fits

In Plusy, Hint on a column question lights up the column and asks a question without giving the answer. A second tap fills in that single step and explains it, and then the sum goes back to your child. It never solves a whole question in one go. See hints and steps.

For practice after the homework is in, or before a quiz, you can scan a worksheet: take a photo, and Plusy reads the questions and works out every answer itself, so the school's own sums become a short game. It reads one-step questions with whole numbers, and fraction questions up to mixed numbers, and shows the reason for anything it skips. A free account has one scan a day, and the photo is never stored.

Plusy does not do the homework and it does not replace the note to the teacher. Start free.
