How Much Maths Revision Should My Child Be Doing?

Parents often ask how much maths revision their child should be doing.

Unfortunately, there is no single correct number.

Ten focused minutes can be useful. An hour spent staring resentfully at the same question may achieve almost nothing. The quality, regularity and difficulty of the work matter at least as much as the amount of time spent doing it.

However, parents still need something more useful than “it depends”.

As a broad guide, most secondary-school students will benefit from short, regular maths practice throughout the year, with the amount increasing gradually before important assessments.

A sensible weekly guide

For ordinary weeks without major exams approaching, a reasonable starting point is:

• Years 7 and 8: around 20 to 40 minutes a week outside normal homework;
• Year 9: around 30 to 60 minutes a week;
• Year 10: around 60 to 90 minutes a week;
• Year 11: around 90 minutes to three hours a week, depending on confidence, current grade and how close exams are.

These are not compulsory quotas.

A student who is secure in maths and completes regular school homework may need less. A student with significant gaps, poor attendance or an ambitious target grade may benefit from more.

The important point is that the time should usually be divided across several shorter sessions.

Three 20-minute sessions are generally more effective than one unhappy hour on Sunday evening.

Revision should increase before exams

During the weeks leading up to mock exams or GCSEs, it is reasonable for revision to increase.

A Year 11 student might complete:

• 20 to 30 minutes on several school nights;
• one longer session at the weekend;
• additional exam-paper practice as the examination approaches.

That does not mean they should spend every evening doing maths.

Students usually have several subjects to revise, as well as school, homework, sleep and some faint hope of remaining pleasant company.

A revision plan must be sustainable. An overambitious timetable may survive for three days before collapsing completely.

Regular practice is better than cramming

Maths is not revised particularly well by reading.

Students improve mainly by attempting questions, checking their work, correcting mistakes and returning to weak topics later.

This is why a small amount of regular practice is so valuable. It keeps methods familiar and reveals gaps before they become urgent.

Cramming can produce short-term improvement, particularly with facts and formulas, but it is less effective for building secure mathematical understanding.

A student who completes 15 or 20 minutes of focused maths several times a week is often in a stronger position than one who suddenly attempts six hours the day before an exam.

What should a revision session look like?

A useful short session might include:

1. a few questions on a topic the student already understands;
2. focused practice on one weaker skill;
3. immediate checking and correction;
4. one or two mixed questions requiring the student to choose the method.

For example, a 25-minute session could involve:

• five minutes recalling key facts or formulas;
• fifteen minutes answering questions;
• five minutes checking errors and recording what needs further practice.

The final five minutes are important.

Students sometimes judge revision by the number of questions completed. In reality, the mistakes often contain the most useful information.

Should my child complete full exam papers?

Full papers are useful, but they should not be the only form of revision.

Early in the revision process, topic-based practice is often more effective. It allows a student to improve a specific weakness without being constantly interrupted by unrelated questions.

Full papers become increasingly valuable closer to exams because they help students practise:

• choosing the correct method;
• moving between topics;
• managing time;
• deciding when to leave a difficult question and return later;
• maintaining concentration;
• checking answers under realistic conditions.

A sensible approach is to combine both.

Use topic practice to fix gaps, then use exam papers to test whether the student can recognise and apply those methods independently.

How can I tell whether the revision is effective?

Time spent at a desk is not the same as useful revision.

Look for evidence that your child is:

• answering questions rather than mainly reading notes;
• checking their answers;
• correcting mistakes;
• revisiting weak topics;
• gradually becoming less dependent on worked examples;
• remembering methods several days later.

A student may appear busy while copying solutions or watching long revision videos without attempting anything themselves.

Videos and worked examples can be helpful, but they should normally lead to active practice.

A useful question to ask is:

“What can you do now that you could not do at the start of the session?”

That is more revealing than asking how long they revised.

What if my child is far behind?

If your child has substantial gaps, simply increasing the number of revision hours may not solve the problem.

They may need help identifying which earlier skills are preventing progress.

For example:

• difficulty with fractions may affect ratio, probability and algebra;
• weak multiplication skills may slow down almost every calculation;
• poor understanding of negative numbers may create problems in graphs and equations;
• weak algebra basics may make later GCSE topics feel impossible.

In this situation, revision should begin with the underlying gap rather than repeatedly attempting work that is currently too difficult.

A teacher or tutor may be able to identify the most important starting points.

What if my child refuses to revise?

This is common, particularly when a student lacks confidence.

Avoid beginning with a huge timetable. A requirement to complete “two hours of maths revision” may feel impossible before the student has even opened a book.

Start with a smaller agreement:

• ten focused minutes;
• five questions;
• one clearly defined topic;
• stop after the agreed task has been completed properly.

Once a routine exists, the amount can increase.

Giving the session a clear endpoint also helps. “Do some maths” is vague and potentially endless. “Complete these six questions and check them” feels manageable.

Should parents supervise revision?

Some students work well independently. Others benefit from a little structure.

Parents can help by:

• agreeing when the session will happen;
• reducing obvious distractions;
• helping choose a specific task;
• checking that answers have been reviewed;
• encouraging consistency rather than demanding perfection.

You do not need to stand over your child or teach every topic yourself.

Too much supervision can turn revision into a performance for the parent rather than useful independent practice.

The eventual goal is for the student to recognise what they need to work on and take increasing responsibility for doing it.

Watch for signs of overload

More revision is not always better.

A student may need to reduce or reorganise their workload if they are:

• regularly working very late;
• becoming unusually anxious or irritable;
• unable to concentrate;
• completing large amounts of work without remembering it;
• abandoning sleep, exercise or normal breaks;
• trying to maintain an unrealistic revision timetable.

Rest is not wasted time. Sleep plays an important role in memory, concentration and exam performance.

A tired student completing a fourth hour of poor-quality revision may gain less than one who stops, sleeps and returns the next day.

Using self-marking practice

Self-marking questions can make short revision sessions easier to manage.

Students can attempt a small set of questions, receive immediate feedback and generate another set when they need more practice.

ESHEETS provides interactive maths worksheets covering a growing range of secondary-school topics. Many worksheets can also be printed, allowing students to work on paper where that is more appropriate.

The worksheets are particularly useful for short, focused sessions rather than attempting to replace a complete revision programme.

A realistic answer

So, how much maths revision should your child be doing?

For most students, the best answer is:

A manageable amount, several times a week, with a clear purpose.

Start small. Make it regular. Focus on answering questions and correcting mistakes. Increase the amount gradually before important exams.

A calm 20-minute session completed properly is worth far more than an hour spent negotiating, avoiding the task and occasionally pressing buttons on a calculator.
