You don't need to know the maths to help with GCSEs. What helps without it, what to say when you're stuck, when help backfires, and how to use AI safely.
Your child brings their maths homework to the kitchen table and asks for help with simultaneous equations. You can't remember how to solve them, and the method in their book isn't the one you were taught. One parent in our autumn 2026 survey worried that their child wouldn't "understand a topic that I can't explain to them", and about "having to pay for tutoring". Yet about two-thirds of the parents we surveyed said their child had relied on help from them or their family in the last year. This page is about making that help count when you can't check the maths.
Key Takeaways
- In the early secondary years (ages 11 to 14), the kind of involvement most strongly linked to achievement doesn't need subject knowledge: talking about why learning matters, setting expectations and discussing how to study (Hill and Tyson, 2009).
- Direct help with the content is where parents' support works least well. The EEF advises routines and good homework habits, and caution about direct homework help for older children (EEF).
- AI can help a parent who doesn't know the maths, if every question starts from a past paper and no answer is trusted until it's checked against the published mark scheme.
No. For 11 to 14 year olds, the involvement most strongly linked to achievement is talking about why learning matters, setting expectations and discussing how to study. Help with homework has the weakest link, and sometimes a negative one (Hill and Tyson, 2009).
The Education Endowment Foundation's guidance for schools agrees. Parents can most usefully support self-regulation, meaning goal-setting, planning, sticking at it and managing time and emotions, "rather than direct involvement in the academic content" (EEF, Working with Parents to Support Children's Learning). The same report describes a trial in UK secondary schools where parents received weekly texts about upcoming tests and missing homework. Their children made one month's additional progress in maths, and none of the texts asked parents to teach any maths: they told parents what was coming up and what was missing.
A good study space has the phone in another room, everything your child needs to hand, and a set time each day rather than whenever they get round to it. "Working with your phone off" is one of the study tips the EEF suggests schools send home. A cleared kitchen table at the same time each evening does more than an occasional session in a bedroom full of distractions.
"What did you learn today?" checks that something went in. "Did you do your homework?" only checks that it was done. You don't need to understand the answer: asking "can you explain that a different way?" turns your child into the teacher, and teaching is one of the better ways to learn. Students who taught a lesson after studying it remembered more a week later than students who only prepared to teach it (Fiorella and Mayer, 2013).
Re-reading and highlighting feel like studying but leave little behind. Active revision looks different: your child is answering past paper questions, working problems before looking at the worked example, or testing themselves with flashcards. This is called retrieval practice: testing from memory. What a week of active revision looks like is set out in how to revise for GCSEs.
Quick Test: Ask your child to close their notes and tell you five things they just revised. If they struggle, the revision has been passive, and that tells you what to change.
You don't need to understand algebra to see that your child doesn't: the same topic avoided every week, homework that takes an hour and comes back with low marks, or "I just don't get it" about one topic. When that happens, the EEF suggests sending a struggling child back to their teacher rather than taking on the teaching yourself, since parents may not know the methods schools use. If that isn't enough, the signs a child needs a GCSE tutor will help you judge whether outside help is worth paying for.
Hopes help, up to a point. Parents who hoped for much more than they expected their child could manage saw lower maths achievement over time (Murayama et al., 2016). Aim your expectations at the next grade your child can realistically reach, and say "we're here to help" more often than "work harder".
If Homework Becomes a Battleground: In our teachers' experience, when a child keeps resisting one subject, the understanding usually isn't there, and more pressure won't put it there. Find out what the gap is before you push harder.
"I don't know, sorry" ends the conversation. These keep it going without you knowing the maths:
One thing not to say is "I never got maths either." It's meant kindly, but it tells your child that being bad at maths runs in the family and can't be helped. In one study, children of parents who were anxious about maths learned less of it over the year. That only happened when those parents often helped with homework (Maloney et al., 2015). "I don't know this one, so let's find how your teacher showed you" keeps the door open.
Yes. Parents' involvement in homework has been linked with lower maths achievement, especially for 11 to 14 year olds. Setting rules and routines was the exception (Patall, Cooper and Robinson, 2008). Part of that is parents stepping in because a child is already struggling. Part is how they step in: a review by Pomerantz and colleagues found that how parents get involved matters more than how much (Pomerantz, Moorman and Litwack, 2007). Controlling help, like taking the pencil or directing each step, tends to backfire. Help that lets your child try first and lead works better.
You work it out together, the homework comes back marked correct, and next week they can't do the same topic alone in a test. The teacher saw a right answer and never learned there was a gap. If your child can only do it with you sitting beside them, they can't do it yet, and their teacher needs to know.
You can't mark the maths, but you can watch how your child works:
Yes, with one rule. You can't check the maths, so don't ask an AI to make up the maths. Tools like ChatGPT can give confident answers that are wrong, and ChatGPT's own interface warns that it can make mistakes. A worksheet you can't check is no help to a child who can't check it either.
So start from real material, and use AI for the parts it's good at: explaining, rephrasing and suggesting things to ask.
Step 1: Get a real question. Past papers and mark schemes are on the exam board websites, some free and some through the school. Ask the school which board your child sits (AQA, Edexcel or OCR). Our parents' guide to GCSE maths explains how the papers work and links to each board's resources.
Step 2: Ask the AI to explain the topic to you, not to your child. For example:
"I'm a parent and I don't remember any GCSE maths. My child is revising simultaneous equations. Explain in plain English what the topic is about, what a typical question asks, and the two or three mistakes students most often make. Don't solve anything yet."
You now know enough to have a conversation.
Step 3: Make more questions from the original. Paste in a past paper question and ask:
"Here is a GCSE maths question from a past paper. Write three more questions in exactly the same style and difficulty, changing only the numbers. Keep the answers whole numbers. Don't give the answers."
Changing only the numbers keeps the new questions close to what the exam board asks, which a question invented from scratch may not be. Asking for whole-number answers matters: change the numbers in a pair of simultaneous equations at random and you can get an answer like x = 17/23, or no solution at all.
Step 4: Check against the published mark scheme, not the AI. Your child does the original past paper question first, and you match their final answer against the published mark scheme. Leave the method marks to their teacher. For equation questions like the new ones, your child can check their own answers by putting the numbers back into both equations. If they don't fit, something is wrong, whether in the working or in the question.
Step 5: Use it to make dinner-table questions. Ask:
"Give me five questions I could ask my child at dinner about simultaneous equations. Make them questions they answer by explaining their method in words, not by calculating."
This is the lowest-risk use for a parent: the AI writes questions, your child does the explaining, and nobody has to trust the AI's maths.
Don't hand the AI to your child to do their homework. If it does the work, they don't learn it, and the teacher sees correct work while the gap stays hidden. In one study, maths students who practised with an AI chatbot did better while they had it, then worse in the exam than students who never had it (Bastani et al., 2025). And check every answer against the published mark scheme, not the AI's verdict.
ChatGPT's interface warning checked on 15 October 2026. Next check: January 2027, or sooner if the tools change.
Home help stops being enough when the gap is in the understanding itself: the topic is still lost after the teacher has been asked, or marks keep falling. Routine won't teach a topic that was missed in class, and that's when paying for help is worth weighing up. How to choose an online tutor sets out what to ask before you sign up. If your child is in Year 7, our guide to the Year 7 maths dip explains how to tell a normal dip from a real gap.
Tugo runs weekly online maths classes of six to eight students, each taught by a PGCE-qualified teacher. During each lesson, the Tugo Teaching Assistant checks students' work and alerts the teacher to mistakes, and you can read where AI sits across UK tutoring if you're comparing options. If you'd like to see where your child's gaps are, our free first lesson includes a diagnostic assessment.
Stick with the school's method rather than teaching your own alongside it. Ask your child to show you the worked example from their lesson, and if they still can't follow it, send the question back to their teacher.
In our classes, refusal is more often a confidence problem than a motivation one. Find out which topic is being avoided, ask the teacher about it, and start small: fifteen minutes of testing from memory, not two hours. How to revise for GCSEs explains how to build from there.
Yes, to understand the topic yourself and to make new questions from past papers. Don't use it to invent maths you can't check, and don't let it mark your child's work: check answers against the exam board's published mark scheme.
