If you've ever felt guilty about not doing enough maths practice with your child, this is your permission slip to stop.
Because here's what the research actually says: shorter, more frequent practice sessions are not just good enough; they're more effective than longer ones. And we're talking five minutes. The time it takes to make a cup of tea.
The science bit (kept short, we promise)
In the 1880s, a German psychologist named Hermann Ebbinghaus mapped out what he called the "forgetting curve": the rate at which our brains shed new information if we don't revisit it. His finding was uncomfortable but simple: we forget most of what we learn within 24 hours if we don't see it again.
The fix isn't to study longer. It's to study again, sooner.
This is the principle behind spaced repetition: revisiting information at regular intervals to move it from short-term into long-term memory. It's the same reason you can still remember your childhood phone number but forgot what you had for lunch on Tuesday.
For primary school maths, this is particularly powerful. Number facts (addition bonds, times tables, subtraction) aren't concepts to be understood once and filed away. They're skills that need to be automated, so a child can recall them instantly without burning mental energy that should go towards solving the actual problem.
Short daily drills do exactly that. Long weekly sessions largely don't.
Why long sessions backfire
Sit a seven-year-old down for 45 minutes of maths practice and you'll likely get one of two things: a child who switches off after ten minutes, or a child who powers through but retains very little by the following week.
Cognitive load research tells us that young children's working memory is limited. Once it's full, new information simply doesn't stick; it's like trying to pour water into an already full glass. Shorter sessions mean the glass never overflows.
There's also the motivation problem. Long sessions feel like hard work for the child and for you. They create friction, arguments, and the kind of negative associations with maths that can last years. Five-minute sessions feel manageable. They end before anyone gets frustrated. And crucially, they're easy enough to actually happen every day.
What five minutes actually looks like
You don't need a curriculum plan. You don't need to know what year group your child is working at. You just need a worksheet and a timer.
- Set a timer for five minutes
- Sit with your child (or nearby; presence matters more than hovering)
- Let them work through as many questions as they can
- Stop when the timer goes, regardless of how far they've got
That's it. No marking marathon. No red pen guilt. Just five minutes, done.
Over days and weeks, you'll start to notice something: the questions they used to pause on, they now answer without thinking. That's automaticity forming. That's the goal.
The marking problem nobody talks about
Here's the part most parenting advice skips over: the practice only works if children get feedback. A child who writes a wrong answer and never finds out it's wrong doesn't learn; they just practise the mistake.
But marking worksheets takes time. It can easily take longer than the practice itself, which is partly why so many parents give up on home drills altogether.
This is exactly the problem redmarker was built to solve. Point your phone camera at a completed worksheet and it marks it in seconds: green ticks for correct answers, red markers for errors. No sitting down with an answer sheet. No mental arithmetic on your part. Just instant, accurate feedback your child can act on immediately.
Because feedback that comes five days later, when the worksheet has been buried under a school bag, isn't feedback at all.
The one thing that matters more than anything else
Consistency beats intensity every time.
Five minutes today, five minutes tomorrow, five minutes the day after. That's what builds maths confidence. Not a two-hour session on a Sunday afternoon. Not a panic revision push before SATs. Just a small, sustainable habit that becomes as unremarkable as brushing teeth.
You've got five minutes. That's enough.
Key takeaways
- Spaced practice: short, frequent sessions beat rare long blocks for moving facts into long-term memory.
- Cognitive load: young children hit a working-memory ceiling; shorter sessions stay under it.
- Routine: a simple timer and worksheet are enough. Stop when the bell rings.
- Feedback: fast checking matters; delayed marking often isn't feedback at all.
redmarker is a free app for iOS and Android that marks maths worksheets using your phone camera, so the practice actually gets checked.
