Growth mindset in maths: what to say when your child says "I can't do it"
"I'm just not a maths person" is a belief, not a fact — and the words you use at homework time can change it.
"I'm just not a maths person." If you have heard your child say this, you know how quickly it can end a homework session. The frustrating part is that it is rarely true. It is usually a belief formed after a few bad test results, and beliefs shape effort. A child who thinks they cannot do maths stops trying, and then the marks confirm the belief.
The good news is that what you say at the kitchen table can change this. Here is how South African parents can build a growth mindset in maths, and why the words you choose matter more than you might think.
What is a growth mindset in maths?
A growth mindset is the understanding that ability grows with effort, good strategies and feedback. It was popularised by psychologist Carol Dweck, and the idea is simple: the brain strengthens with use, much like a muscle. A child with a fixed mindset says, "I'm bad at fractions." A child with a growth mindset says, "I haven't mastered fractions yet."
That small word "yet" matters because maths in the CAPS curriculum is cumulative. Most children who struggle in Grade 7 or Grade 9 are not incapable. They have specific gaps from earlier work that were never closed, and gaps can be closed.
Swap these phrases at homework time
Children listen closely to how adults talk about maths. Even well-meant comments can send the wrong message.
- Instead of "You're so clever!" say "I can see how hard you worked on that."
- Instead of "Don't worry, I was bad at maths too" say "This is tricky, and tricky is how your brain grows."
- Instead of "Just follow the steps" say "What have you tried so far?"
- Instead of "You got 40%, what happened?" say "Which questions cost you marks? Let's look at them together."
- Instead of "You'll never get this" (even as a joke) say "You can't do this yet."
Praising effort and strategy, rather than intelligence, tells your child that they control the outcome. Praising "cleverness" does the opposite: it makes mistakes feel dangerous, because a mistake suggests you are not clever after all.
Make mistakes useful
Children with a fixed mindset hide wrong answers. Children with a growth mindset use them. You can model this by treating errors as information. When your child gets a question wrong, ask them to explain their thinking before you correct anything. Often the logic is almost right, and the slip is one small step.
Keep one page where your child writes the question, what went wrong and the fix. Over a few weeks, patterns appear: perhaps negative signs, or carrying in long division. Patterns are far easier to fix than a vague feeling of "I'm bad at maths."
Give them evidence that they are improving
Mindset does not change through slogans. It changes through proof. A child who has failed three tests needs to see, with their own eyes, that they can get better.
That means practice pitched at the right level. If the work is too hard, they confirm their belief that they cannot do it. If it targets their actual weak areas, they start winning. Equals2 was built for this: it tracks how your child performs, identifies the topics they find difficult, and serves up practice on exactly those areas. If the gap goes back a grade or two, students can step back through earlier grades and terms and rebuild from there, without anyone feeling judged.
Watching their own scores rise on a topic they once avoided is far more persuasive than any pep talk. Short, regular sessions of 15 to 20 minutes work better than a long weekend panic.
Be patient, and keep it up
Shifting a belief takes weeks, not days. Expect "I can't" to come back after a bad mark. When it does, stay calm, acknowledge the frustration and point back to the evidence: "Remember how hard fractions felt in March? Look how far you have come."
As the end-of-year exams approach, this matters even more. A child who sees a hard paper as a challenge to attempt, rather than a verdict on their ability, performs better under pressure.
Your child is not a "maths person" or a "non-maths person." They are a learner at a particular point on the path, and that point moves.
