Have you ever watched a child struggle to answer a simple maths question — not because they don’t know it, but because they take too long to recall it? That’s the difference between knowing maths and owning it.
This article is for parents, teachers, and KS1 and KS2 learners who want to turn slow thinking into sharp, confident mental maths. Whether your child is still learning to add single digits or working through their times tables, the goal is the same: make answers feel automatic.
Inside, you’ll find step-by-step exercises, clever tricks, common mistakes to avoid, and a highly effective way to practise using Hit the Button — a free interactive maths game that builds real speed through repetition and play.
By the end, you’ll have everything you need to help any child go from hesitant to confident in mental maths. Let’s get started.
What Are Brain Speed Maths Exercises?
Brain speed exercises are short, focused maths activities designed to improve how quickly and accurately a child can recall number facts.
Think of it like learning to ride a bike. At first, every movement requires thought. With enough practice, your brain stops thinking consciously — it just reacts. Maths fluency works the same way.
These exercises typically cover:
- Addition and subtraction facts
- Times tables and division facts
- Number bonds to 10, 20, and 100
- Doubling and halving
- Square numbers and simple fractions
The aim isn’t just to get the right answer. It’s to get the right answer fast — without using fingers, counting out loud, or pausing to work things out from scratch.
Why This Skill Matters for KS1 and KS2 Learners
The UK National Curriculum places a strong emphasis on mental maths fluency at both KS1 and KS2. By the end of Year 2, children are expected to recall addition and subtraction facts within 20. By Year 4, every child must pass the Multiplication Tables Check (MTC) — a timed test covering all tables from 2 to 12.
But it goes beyond tests.
When a child has instant recall of number facts, their working memory is freed up to tackle harder problems. Instead of spending mental energy calculating 6 × 7, they can focus on the actual challenge in front of them — whether that’s solving a word problem, working out change, or following a multi-step equation.
Research in cognitive science consistently shows that fluency in foundational number facts:
- Strengthens overall mathematical confidence
- Reduces maths anxiety
- Improves performance in higher-level topics like fractions, algebra, and ratio
- Builds the kind of number sense that transfers to everyday life
From telling the time and splitting a restaurant bill to budgeting pocket money — fast mental maths is a life skill, not just a school skill.
Step-by-Step Learning Guide: Building Maths Fluency
Step 1: Start With Number Bonds
Number bonds are pairs of numbers that combine to make a target number. They are the foundation of all mental maths.
Example: Number bonds to 10 — 3 + 7, 6 + 4, 9 + 1
Once a child knows these automatically, adding larger numbers becomes far easier. Knowing that 3 + 7 = 10 instantly unlocks 13 + 7 = 20, and 30 + 70 = 100.
How to practise: Call out a number and ask your child to shout the “partner” that makes 10. Do it fast, like a game. Aim for zero hesitation.
Mini tip: Start with bonds to 10 before moving to 20, then 100. Don’t rush this stage — it underpins everything else.
Step 2: Learn Times Tables in the Right Order
Not all times tables are equally difficult. A smart approach is to learn them in order of ease and overlap.
Start with: 2s, 5s, 10s (high pattern visibility) Then move to: 3s, 4s, 6s Finally tackle: 7s, 8s, 9s (hardest for most children)
Example: The 9 times table has a brilliant pattern — the digits always add up to 9. So 9 × 4 = 36 (3 + 6 = 9), 9 × 7 = 63 (6 + 3 = 9). Once children spot this, they stop guessing.
Mini tip: Use Hit the Button’s times tables mode to practise one table at a time. The timed format mimics the pressure of the Year 4 MTC — perfect preparation.
Step 3: Practise Division as the Flip Side
Many children learn their times tables but freeze when asked a division question. The fix is simple: teach division alongside multiplication from the start.
Example: If your child knows 6 × 8 = 48, they should immediately be able to answer 48 ÷ 6 = 8 and 48 ÷ 8 = 6.
Frame it as a triangle: put 48 at the top, 6 and 8 at the bottom. Any side can be calculated from the other two.
Mini tip: When drilling times tables, always follow a multiplication question with its inverse. This doubles learning with no extra effort.
Step 4: Introduce Doubling and Halving
Doubling and halving are often underestimated, but they are powerful mental maths shortcuts.
Example: Not sure of 14 × 4? Double 14 to get 28, then double again to get 56. Done.
Mini tip: Make doubling a daily habit. At dinner, ask: “If we had double the pasta, how much would we have?” It builds the skill without it feeling like homework.
Easy Tricks and Shortcuts for Faster Maths
The “Near Ten” trick for addition When adding 9, add 10 and subtract 1. So 47 + 9 = 47 + 10 − 1 = 56. Much faster than counting up.
The finger trick for the 9 times table Hold out 10 fingers. To calculate 9 × 3, fold down the 3rd finger. You have 2 fingers to the left and 7 to the right. Answer: 27. Works for 9 × 1 through 9 × 10.
Splitting numbers (partitioning) To add 36 + 47, split into 30 + 40 = 70, then 6 + 7 = 13, then 70 + 13 = 83. Keeps the sum manageable.
The square number shortcut Knowing your square numbers (1, 4, 9, 16, 25, 36…) helps with estimation and multiplication. If a child knows 7 × 7 = 49, they can quickly calculate 7 × 8 by just adding one more 7.
Multiplying by 5 Multiply by 10 first, then halve. So 14 × 5 = 140 ÷ 2 = 70. Always quicker than counting up in fives.
Common Mistakes and How to Fix Them
Mistake 1: Counting on fingers for every answer Why it happens: The child hasn’t moved past the “working out” stage to the “recalling” stage. Fix: Drill the same small set of facts daily until they become automatic. Don’t move on until there’s zero hesitation.
Mistake 2: Learning tables by chanting without understanding Why it happens: Reciting “six sevens are forty-two” is not the same as knowing it. Fix: Always follow chanting with random-order questioning. The order of the table should be irrelevant.
Mistake 3: Skipping difficult tables and only drilling easy ones Why it happens: Confidence feels better than struggle. Fix: Use a game like Hit the Button maths mode to surface weak spots. Games make difficult practice feel manageable.
Mistake 4: Practising too long in one session Why it happens: Parents assume more time equals more learning. Fix: Five minutes of sharp, focused practice beats 30 minutes of distracted drilling every time.
Mistake 5: Only practising multiplication, not division Why it happens: Division feels like a separate topic. Fix: Always pair them. Every multiplication fact is also a division fact — practise both simultaneously.
Mistake 6: Quitting when the timer runs out on a game Why it happens: The child feels embarrassed or frustrated. Fix: Reframe the timer as a tool, not a test. The point is improvement, not perfection. Yesterday’s score is today’s target.
Mistake 7: Irregular practice Why it happens: Busy schedules push maths practice out. Fix: Attach practice to an existing routine — after breakfast, before bed, or during a car journey. Consistency matters more than duration.
Fun Practice Methods That Actually Work
At home:
- Flashcard races — one card per second, child calls out the answer
- Whiteboard challenges — write a question, child has to answer before you count to three
- “Beat the clock” sessions using a kitchen timer
- Maths at mealtimes — ask quick questions while setting the table or eating breakfast
In the classroom:
- Table tennis maths — teacher asks, child answers, child asks back
- Mini whiteboards for instant response activities
- Maths stations with timed challenges at each one
- Pair drilling where children quiz each other
In everyday life:
- Supermarket sums — “If that costs £3 and we have £10, how much change?”
- Halving recipes when cooking together
- Calculating journey times and distances on car trips
- Scoring in card games using mental addition
The key is to make number facts feel normal — part of ordinary conversation, not a separate school activity.
Practise This Skill Using Hit the Button
If you’re looking for one tool that builds maths brain speed better than almost anything else, Hit the Button is it.
Hit the Button is a free, fast-paced maths game designed specifically for KS1 and KS2 learners. Children answer questions by clicking the correct answer before time runs out — and the format is perfectly aligned with how the brain builds automatic recall.
Here’s why it works so well:
Speed: The timed format forces the brain to retrieve answers quickly, moving children from “working out” to “knowing.” This mirrors the pressure of the Year 4 Multiplication Tables Check without the stress of a formal test.
Accuracy: Hit the Button doesn’t reward guessing. Children quickly learn that careful recall beats random clicking — and that trains the brain to focus.
Confidence: Because children can choose which topic to practise — number bonds, times tables, doubles, halves, or division — they can start where they feel safe and build up. Seeing a high score go up is a powerful motivator.
Variety: The game covers a wide range of topics. You can practise hit the button times tables one day, then switch to number bonds or hit the button maths division the next — keeping practice fresh without needing multiple resources.
Whether used for five minutes at home or as a classroom warm-up activity, Hit the Button maths delivers results. Teachers across the UK use it regularly because it’s curriculum-aligned, zero-prep, and genuinely engaging for children.
Give it a try — and challenge your child to beat their own score.

Expert Tips for Parents and Teachers
Set a daily five-minute target, not a topic target Five minutes of daily practice, every day, produces far better results than a 30-minute session once a week. Consistency wins.
Focus on one table until it’s solid Don’t move from the 6 times table to the 7 times table until a child can answer any fact from the 6s in under three seconds — in any order.
Use retrieval, not just revision There’s a crucial difference. Revision means looking at facts. Retrieval means being asked and having to produce the answer without looking. Retrieval is what builds memory. Always test, not just review.
Praise effort and progress, not just correct answers A child who answers wrongly but quickly is making good progress. Acknowledge the attempt, correct gently, and move on.
Track scores over time Whether using Hit the Button or paper tests, keep a simple record of scores. Children are motivated by visible progress. A chart on the fridge works brilliantly.
Don’t drill when tired or stressed The brain doesn’t consolidate memories well under stress. Keep practice calm, short, and positive.
Advanced Insight: The Science Behind Maths Fluency
Here’s something most maths practice resources don’t tell you: the way you practise matters just as much as how often you practise.
Two principles from learning psychology are particularly powerful for maths fluency.
Spaced retrieval means spreading practice out over time, rather than cramming. If a child practises the 7 times table on Monday, revisits it briefly on Wednesday, and is tested again on Friday, they will remember it far better than if they drilled it for an hour on one day. The gaps are what make the memory stick — because each retrieval strengthens the neural pathway.
Interleaved practice means mixing different topics together, rather than practising one in isolation. Instead of doing 20 questions from the 6 times table, do 5 from the 6s, 5 from the 8s, 5 number bonds, and 5 division questions. This feels harder — and it is — but it produces significantly stronger long-term recall.
This is exactly why a game like Hit the Button is so effective. It naturally creates retrieval conditions (you must recall, not recognise), and switching between topics introduces a mild form of interleaving.
The children who build the strongest maths fluency aren’t necessarily the ones who work the longest. They’re the ones who practise smarter — with frequent, varied, retrievable exposure to number facts over time.
You can also explore related skills alongside mental maths — topics like number bonds, place value, and fraction recognition all reinforce the same underlying number sense that makes brain speed exercises so effective.
Frequently Asked Questions
What is Hit the Button? Hit the Button is a free interactive maths game for KS1 and KS2 children. It covers times tables, number bonds, doubling, halving, and division. Children answer questions against a timer, which builds mental maths speed and recall in a fun, low-pressure way.
Is Hit the Button suitable for KS1 children? Yes. Hit the Button includes simpler topics like number bonds to 10 and doubling small numbers, making it accessible for Year 1 and Year 2 children. You can select the topic and difficulty to match your child’s current level.
How often should children practise mental maths? Daily practice, even for just five minutes, is ideal. Little and often is far more effective than occasional long sessions. Aim for consistency rather than volume.
My child knows their tables when calm but forgets them in tests — why? This is very common and usually means the facts aren’t fully automatic yet. They know them consciously but not instinctively. More retrieval-based practice — especially under mild time pressure like Hit the Button — will help move those facts into automatic recall.
What’s the best order to learn times tables? Start with 2s, 5s, and 10s, then move to 3s, 4s, and 6s, before tackling 7s, 8s, and 9s. Always pair multiplication with division from the beginning.
What is the Year 4 Multiplication Tables Check? The MTC is a national assessment taken by all Year 4 pupils in England. Children answer 25 multiplication questions — drawn from tables 2 to 12 — in under 25 seconds. Regular timed practice using tools like Hit the Button maths is the best preparation.
Can Hit the Button replace classroom maths practice? It’s a supplement, not a replacement. Hit the Button is excellent for building recall speed, but it works best alongside classroom teaching, written work, and varied problem-solving activities.
Conclusion: Small Daily Practice, Big Results
Building maths brain speed isn’t about talent — it’s about repetition, routine, and the right kind of practice.
The children who become fluent in mental maths are rarely the ones who sit down for long study sessions. They’re the ones who practise a little every day, mix up their topics, and spend time retrieving answers under gentle pressure — not just reviewing what they already know.
Start with number bonds. Build times tables one at a time. Practise division alongside multiplication. Use the tricks and shortcuts in this article. And most importantly, make practice a normal, low-stress part of the day.
Hit the Button is one of the simplest and most effective tools you can use right now — free, curriculum-aligned, and genuinely fun for children. Even five minutes a day will produce visible improvement within weeks.
The goal isn’t perfection. The goal is progress — a little faster today than yesterday, a little more confident this week than last.
Keep going. The fluency will come.
