What homework is actually for, by age

This is less a set of instructions about homework than an argument, and it is worth saying so at the start.

The evidence is age-dependent

Research reviews consistently find little measurable academic benefit from homework in primary school. In secondary school the association with attainment is clearer, particularly where the work is short, focused and feeds back into teaching. This does not mean primary homework is pointless; it means its purpose is something other than raising attainment.

Reading together is the one primary activity with strong and consistent evidence behind it.

What primary homework is really doing

Establishing a habit, giving parents visibility of what is being taught, and practising a small amount of recall. Judged against those aims, ten minutes of engaged work is a success and forty minutes of conflict is a failure. Schools rarely say this out loud, which is why families over-invest in it.

For some children it is also the only regular occasion on which they are stuck and then get unstuck with an adult beside them, which is worth more than the content of any particular worksheet.

Protect a slot rather than enforcing a duration

A consistent time and place removes most of the daily negotiation, which is where the conflict actually lives. Immediately after school suits some children and is disastrous for others who need a break first.

Whichever it is, keeping it consistent matters more than which one you pick. Where a week genuinely has no repeating shape — shift work, two households, clubs on different evenings — a daily slot is not available, and picking two predictable evenings rather than pretending to every evening is the version that survives.

Help with the process, not the answers

Doing the work produces a good-looking book and no learning, and teachers can tell. Useful help looks like reading the question together, breaking it into steps, and leaving.

Stopping and writing a note to the teacher that it was too hard is legitimate and genuinely useful feedback. Methods for arithmetic and spelling taught in school frequently differ from the ones you were taught, and demonstrating yours can leave a child holding two competing procedures, so asking them to show you theirs first avoids a lot of avoidable confusion.

When it is taking too long

Work that consistently takes far longer than the school intends is information about either the work or the child. Telling the teacher is the correct response and is treated as helpful rather than as a complaint.

Over a term, persistent, disproportionate struggle is worth exploring properly rather than absorbing at home every evening. Where the delay is something other than the work — a book left at school, an online platform nobody can log into, an instruction that was never clear — that is worth naming separately, since it is trivially fixable and looks identical to difficulty from the school's side.

If something here does not match your family, trust your family.

Deciding what battles to have

A nightly argument about homework costs more than the homework is worth in most primary settings. Where a family decides to do less and tell the school, that is a legitimate position and many teachers are sympathetic.

In practice, in exam years the calculation genuinely changes, and it is worth saying so explicitly rather than reversing without explanation. Expectations vary widely between countries and between schools within them, so comparisons with other families are frequently comparisons between two different systems rather than between two children.

The takeaway

Protect a short slot, help with the process, and tell the teacher when it is not working.

The thing they remember is rarely the thing you were worrying about.
