My Year 10 child is struggling with GCSE algebra: what should we do?

A practical way for parents to pinpoint an algebra gap, agree the right practice with school, and check whether it is improving.

By Legacy Academy

If your Year 10 child keeps getting stuck on GCSE algebra, start by finding the first step they cannot explain. Ask their maths teacher which skill to revisit, use a small amount of matched practice, then check the same skill again. A low mark on a mixed test does not, by itself, tell you which part of algebra needs help.

This advice is for parents of pupils studying GCSE maths in England. Schools teach topics in different orders, so use your child's current work and teacher's guidance rather than assuming they should have covered every algebra topic by a particular point in Year 10.

Find the exact sticking point

"Algebra" covers several skills. The Department for Education's GCSE maths subject content and AQA's algebra specification include notation, substituting values, simplifying expressions, using brackets and solving equations. A pupil may be confident in one and unsure about another.

Take one recent question that your child attempted. Ask them to talk through what they thought each line meant. For example, with 2(x + 3) = 14:

• If they write 2x + 3 = 14, they may need to revisit multiplying both terms inside a bracket.
• If they correctly reach 2x + 6 = 14 but cannot continue, the gap may be in solving a linear equation.
• If they can solve it but cannot explain why 2x means 2 × x, start with algebraic notation.

The solution is x = 4, but the useful discovery is where the reasoning changed. One example cannot diagnose every difficulty; look for the same pattern in a few pieces of classwork or homework. Keep the conversation curious: "Show me the line that stopped making sense" is more helpful than "Why did you get this wrong?"

Ask the teacher for one priority

Send a short, specific question rather than asking whether your child is simply "behind":

My child is finding algebra difficult in Year 10. In the recent work, they got stuck when expanding brackets and then solving the equation. Which prerequisite should we practise first, and is there a school resource that matches the method you are teaching?

Ask what the teacher has seen across several tasks, what has already been taught, and what a successful next step would look like. If your child has an agreed support plan or a persistent difficulty across subjects, ask the school who should coordinate the support. You do not need to settle those questions from a single homework exercise.

It is also worth asking which exam board and tier your child is currently working towards. AQA distinguishes Foundation and Higher content within its algebra specification. Other boards provide their own specifications. Let the school explain which material is relevant now and when any tier decision will be reviewed; do not make a tier decision from one result.

Make practice small and specific

Once the teacher has identified a priority, choose a short practice set on that skill. A manageable starting routine might be 10–15 minutes on three days in a week, adjusted to your child's workload and concentration. Use the school's recommended questions where possible.

For each session:

1. Start with one worked example. Ask your child to explain why each step follows.
2. Try a few similar questions independently. Resist supplying the next line immediately.
3. Mark and correct promptly. Record the type of error, not just the total score.
4. Return to the skill later. Include one question after a few days to see whether the method is still understood.

An error note can be as simple as: "When expanding 3(x + 2), I multiplied the x but forgot the 2. I need 3x + 6." If the same error persists after explanation and practice, tell the teacher. Repeating a large worksheet without understanding the correction is unlikely to show you what needs changing.

Check progress without turning every evening into a test

After about two weeks, compare a fresh question with the original one. Can your child explain the step that previously caused trouble, use it in a slightly different example, and spot an error in a worked solution? Those checks tell you more about this specific gap than a single percentage from a mixed assessment.

If the skill has improved, ask what to practise next. If it has not, share the examples with the teacher and ask whether the underlying issue is earlier knowledge, the teaching method, or something else. Keep the focus on the work, not on a label for your child.

If your family wants additional one-to-one help with a specific maths gap, Legacy Academy's GCSE maths page explains its online support. You can book a free 45-minute trial lesson to discuss what your child is finding difficult. The separate paid diagnostic is optional; a trial is not a promise of a particular grade.

The next useful step today is simple: choose one attempted algebra question, identify the first unexplained line, and ask the teacher which skill to tackle first.
