Why Does My Child Keep Saying “I Don’t Know” During Homework?

Why Does My Child Keep Saying “I Don’t Know” During Homework?

“I don’t know.”

If you have heard your child say this repeatedly during homework, you may sometimes wonder whether your child is simply not paying attention or not trying hard enough.

But “I don’t know” can mean many different things.

Your child may genuinely not understand the question. They may have forgotten an earlier concept, feel afraid of making a mistake, or simply not know how to begin.

Understanding the reason behind those three words can help parents provide the right support.

1. Your Child May Not Understand the Question

Sometimes, the problem is straightforward: your child does not understand what the question is asking.

This can happen particularly with word problems and questions that require students to apply what they have learned.

Instead of immediately giving your child the answer, try asking:

“Which part of the question do you understand?”

Breaking the question into smaller parts can help your child identify where the confusion begins.

This also encourages your child to think about the problem instead of immediately depending on someone else for the answer.

2. Your Child Has Forgotten an Earlier Concept

A new topic often depends on knowledge that was taught earlier.

For example, a student may struggle with a Secondary Mathematics topic because the student is not confident with a basic concept learned in Primary school.

The current homework may therefore look difficult even though the real problem started much earlier.

This is why simply telling a child to “study harder” may not solve the issue.

The underlying learning gap needs to be identified first.

3. Your Child Doesn't Know How to Start

Some students actually understand parts of a question but do not know what step to take first.

This is common with questions that require several steps.

They may look at the question, feel overwhelmed and immediately say:

“I don't know.”

Teaching students how to break a difficult question into smaller steps can make it much less intimidating.

For example:

What information has been given?

What is the question asking for?

Which concept or formula might be useful?

What should I do first?

Learning this process can gradually help students become more independent.

4. Your Child Is Afraid of Getting the Answer Wrong

Not every “I don't know” means a student has no knowledge.

Sometimes, the student is simply afraid of making a mistake.

This can happen when a child has experienced repeated difficulties in a particular subject.

The child may think:

“I'm probably going to get it wrong anyway.”

As a result, saying “I don't know” feels safer than attempting the question.

Parents can help by treating mistakes as part of learning.

Instead of immediately saying, “You should know this,” try asking:

“Let's see which part you are unsure about.”

A calm response can make it easier for a child to try again.

5. Your Child May Be Tired or Overwhelmed

Children have busy schedules.

School, homework, tuition, projects, examinations and other activities can leave students mentally tired.

When a child is overwhelmed, even a question that would normally be manageable can suddenly seem very difficult.

If your child frequently struggles with homework late at night, consider whether the timing or workload could be contributing to the problem.

Sometimes, a short break can help the child return to the question with a clearer mind.

6. Your Child May Have Become Too Dependent on Help

There is another possibility.

If a child frequently receives the answer immediately after saying “I don't know,” the child may unintentionally learn that asking for help is easier than trying.

This does not mean parents should refuse to help.

Instead, try giving hints rather than complete answers.

For example:

Instead of:

“The answer is 24.”

Try:

“Which operation do you think you need to use?”

This gives your child an opportunity to think independently.

7. The Child May Need a Different Explanation

Sometimes a child has heard the same explanation several times but still does not understand.

That does not necessarily mean the child is incapable.

It may simply mean that the explanation does not match the way the child understands best.

A different example, diagram, method or step-by-step explanation may suddenly make the concept clearer.

This is one advantage of individualized learning.

A tutor can adjust the explanation according to the student's response rather than continuing at the same pace as an entire class.

What Should Parents Do When Their Child Says “I Don't Know”?

The next time your child says “I don't know,” try not to assume that the child is being lazy.

Instead, ask a few simple questions:

“Which part don't you understand?”

“What do you know about the question?”

“Can you tell me what the question is asking?”

“What have you tried so far?”

These questions can help you discover whether the problem is a lack of knowledge, a lack of confidence or difficulty understanding the question.

When Should You Consider Getting a Tutor?

If your child occasionally says “I don't know,” there may be nothing to worry about.

However, if it happens regularly—especially across homework, tests and different topics—it may be worth looking more closely at the situation.

A tutor can help identify areas where the student is struggling and work through them systematically.

With 1-to-1 home tuition, the tutor can also observe how the student approaches questions.

For example, the tutor may discover that the student:

• Understands concepts but lacks confidence

• Has gaps in basic knowledge

• Struggles to understand question wording

• Makes repeated careless mistakes

• Does not know how to structure an answer

• Needs more practice applying concepts

Once the actual problem is identified, lessons can be focused on that specific area.

Helping Your Child Become More Independent

The ultimate goal of tuition should not be for a child to depend on a tutor forever.

It should be to help the student gradually become more confident and independent.

A good tutor can guide the student through difficult questions while also teaching the student how to approach problems independently.

Over time, the goal is for the child to move from:

“I don't know.”

to:

“Let me try.”

And eventually:

“I know how to work this out.”

That change in confidence can be just as important as an improvement in marks.

Finding the Right Tutor for Your Child

Every student has different strengths, weaknesses and learning needs.

A tutor who works well for one student may not necessarily be the right fit for another.

At Tuition Family Singapore, we help parents find suitable 1-to-1 home tutors for Primary, Secondary and JC students.

We believe that finding a tutor is not simply about finding someone who teaches the subject. It is about finding someone who can understand the student's difficulties and provide suitable guidance.

If your child frequently says “I don't know” when doing homework, don't immediately assume that your child is not trying.

Sometimes, those three words are simply a sign that your child needs help understanding where to begin.
