Math homework help that doesn’t give your child the answer

When your child is stuck, the fastest help is the answer. It is also the help that teaches least. Here is what research found, and the questions to ask instead.

Key findings

  • In a field experiment with nearly a thousand high school math students, those who practiced with a standard ChatGPT-style assistant did 48% better on practice problems, then 17% worse on the exam once it was taken away, compared with students who never had it [1][2].
  • A version built to give hints instead of answers lifted practice scores by 127% and largely avoided the exam drop [1][2].
  • The researchers found students used the answer-giving version as a “crutch” during practice [1].
  • For elementary students who struggle, the federal practice guide recommends teaching problem types and having children explain their thinking in precise math language [3].

What happens when kids get the answer

In 2025, researchers published a field experiment in which nearly a thousand high school students practiced math with one of two AI tutors, or with none [1]. One tutor behaved like a standard chat assistant and would simply solve the problem. The other was set up to give hints and guide the student, not to hand over answers [2].

During practice, both groups did better than students without AI: 48% better with the answer-giving tutor, 127% better with the hint-giving one [1][2]. Then the AI was taken away for the exam. Students who had practiced with the answer-giving tutor scored 17% lower than students who never had AI at all. The hint-giving group’s drop was largely avoided [1][2]. The authors’ explanation: students leaned on the answers as a crutch, so the practice didn’t stick [1].

The study was with older students and with AI, but the lesson carries to the kitchen table: help that does the thinking feels good tonight and shows up as a gap on the test.

Ask, don’t tell: the questions to use

  1. “Read it to me.” Many “stuck” children have skipped a word. Reading aloud finds it.
  2. “What is it asking?” Before any numbers. If your child can’t say the question, solving it won’t help.
  3. “What do you know?” Have them point to each number and say what it means in the story.
  4. “Can you draw it?” A quick sketch often shows whether to add, subtract or share out.
  5. “How did you get that?” Ask after right answers too. Explaining is how children catch their own mistakes, and the practice guide recommends it [3].

Wait after each question. Silence is your child thinking, not your cue to explain.

When a question isn’t enough: hint, don’t solve

If your child is still stuck, give the smallest hint that gets them moving, then step back. In order:

  • Point to the part that matters. “Look at the word ‘each.’”
  • Do one small step. “The first box is 8. What comes next?”
  • Work a twin problem. Solve one just like it with different numbers, then hand theirs back.

Only after all that, if they are still stuck, walk through the whole problem, and then have them do the next one alone.

Choosing an app or AI helper

Many homework apps solve a photographed problem and show the full worked solution. That can help a parent check an answer, but for a child it is the answer-giving tutor from the study above [1]. Before your child uses one, try it on a problem yourself and see what it does when you type a wrong answer: does it ask a question, or show the solution?

Look for one that asks what the child thinks first, gives hints in steps, and makes them do the last step themselves.

How Kizupi does it

Kizupi is a math tutor for Grades 1 to 6 built to never hand over the answer first. After a wrong answer it asks the child how they got it. If they are stuck, help comes one rung at a time on a fixed seven-step ladder: wait, read it again, a focus question, a picture, a partial step, a similar problem worked through, and only then a full walkthrough.

Questions parents ask

Is it ever OK to just give my child the answer?

Sometimes, when they have tried, had hints and a worked twin problem, and are still stuck. Then walk through it, and have them do the next problem alone.

Are AI homework helpers bad for kids?

Not by themselves. In the 2025 study, the AI that gave answers hurt exam scores, while the one built to give hints largely did not [1][2]. How the helper behaves matters more than whether it is AI.

What if I don’t know how to do the math myself?

The questions still work: what is it asking, what do you know, can you draw it, how did you get that. You don’t need the answer to ask them.

My child gets upset when I won’t tell them. What do I do?

Say what you’re doing: “I’m not going to tell you, because then you won’t remember it. I’ll help you find it.” Then make the next hint smaller and easier to act on.
