Children practise working with numbers in their head. Simple strategies are explained clearly, demonstrated with examples, and built up through structured activities until your child can calculate without reaching for paper.
One strategy: split the numbers
Brolly Juniors runs mental maths classes in Hyderabad for ages 7 to 14. Children learn number bonds, place-value splitting, compensation and estimation as named strategies they can choose between, then practise until the choice is automatic. Speed is the result of method here, never the starting point.
A short, plain-English explanation you can share with your child.
Mental maths is the ability to work with numbers and solve calculations in your mind, without depending on written steps for every sum. It is not about being fast for the sake of it — it is about having a way to think through a calculation rather than only a procedure to follow.
Children practise by learning a handful of flexible strategies. Splitting a number into tens and ones. Rounding to something friendly and adjusting afterwards. Using a fact they already know to get to one they do not. Estimating an answer before working it out properly.
Number confidence matters because it decides whether a child attempts a question at all. A child with no method will guess or freeze; a child with a strategy will have a go. Over time that willingness matters more than raw speed.
Comfort with numbers comes from regular, manageable practice. Small amounts done often work far better than long sessions done rarely, which is why the programme is built around short activities rather than long worksheets.
Simple explanationWritten maths asks a child to follow one fixed procedure. Mental maths asks them to look at the numbers first and pick an approach that suits them. That small shift is what turns arithmetic from a chore into something a child can reason about.
Easy exampleTo work out 63 − 29, a child can take away 30 to reach 33, then add the extra 1 back to get 34. No borrowing, no crossing out, and nothing to write down.
At Brolly JuniorsOne strategy is introduced at a time, demonstrated, and practised with guidance before a child uses it independently. Book a free trial to see how your child takes to the approach.
The honest answer: it will not turn your child into a different learner overnight, but it gives them a method where they previously had none.
Most children who dislike maths are not weak at it — they are unsure. Having a strategy to reach for removes much of that hesitation, and a confident child attempts more questions.
Children are often told to work things out in their head without ever being shown how. Here the strategies are taught explicitly and then practised.
Everyday arithmetic takes less time and effort, which leaves more attention for the part of a question that actually needs thought.
Holding two numbers in mind while working on a third is genuine mental exercise, and it improves with practice like anything else.
Children learn to estimate before calculating, so an answer that is wildly off gets noticed rather than written down.
Deciding which strategy suits a particular sum is a small decision, but making it repeatedly is how flexible thinking is built.
How much a child gains depends on how regularly they practise and where they are starting from. We do not promise a particular improvement in school marks or a fixed calculation speed — what we commit to is structured teaching and consistent practice.
Eight things children work on across the programme.
Finishing a sum in the head, using a strategy that suits the numbers in front of them.
Being willing to attempt a calculation instead of waiting to be shown how.
Holding numbers in mind through several steps without losing track halfway.
Estimating first so that an answer which cannot be right gets spotted straight away.
Reading a question, working out what it asks, and choosing an approach before calculating.
Understanding why splitting or rounding works, so the idea transfers to new sums.
Short challenges give children a friendly way to see their own fluency improve.
Repeated success with manageable numbers, which is what changes how a child feels about the subject.
Mental maths is not one method. It is a small set of strategies, and part of the skill is choosing which one fits the numbers in front of you. Six examples of what children learn to recognise.
40+30 = 70, then 6+7 = 13
Handle the tens first, then the ones, then combine. Usually the first strategy a child learns, because it works on almost any addition.
63 − 30 = 33, then +1
Change an awkward number into a friendly one, do the easy sum, then correct for the difference. No borrowing needed.
double 8 = 16, then +1
Start from something already memorised and take one small step from it. Children build a lot of new facts this way.
about 300 + 300
A rough answer takes seconds and tells you what to expect. The exact answer here is 601 — anything far from 600 must be a mistake.
78 → 82 is four steps
When two numbers are close, counting up from the smaller one is far quicker than subtracting properly.
check: 63 − 29 = 34
Reversing the sum confirms the answer. Children who build this habit catch their own mistakes instead of waiting to be told.
Understanding comes before speed. A child is asked to explain how they got an answer before being asked to get it faster — a strategy that is only copied tends to be forgotten; one that is understood gets reused.
Five questions using the strategies above. Sit with your child and see how they get on — there is no score to worry about.
27 + 18
Question 1 of 5 — Add 20, then take 2 back.
Each level adds one family of strategies and keeps every earlier one in weekly circulation.
The facts that everything else stands on, learned to the point of not needing thought.
Big numbers become easy ones. 47 + 38 turns into 47 + 40 − 2 and the child says why.
Doubling, halving and factor pairs turn awkward multiplications into ones already known.
Knowing roughly what the answer should be is what catches a mistake before it is written down.
Topics are introduced gradually and revisited, so earlier work keeps being practised as new ideas are added.
Reading numbers confidently, understanding place value, and knowing what each digit is worth — the foundation every strategy sits on.
Splitting numbers into tens and ones, making round numbers, and using known facts such as doubles to reach an answer.
Counting on to find a difference, rounding and adjusting, and subtracting in useful chunks rather than digit by digit.
Building from tables a child already knows, doubling and halving, and breaking a larger multiplication into two smaller ones.
Sharing into equal groups, dividing by simple factors in steps, and checking the result by multiplying back.
Direct practice at holding numbers in mind and finishing without paper, built up slowly so it never feels overwhelming.
Noticing what repeats — in tables, in sequences, in the way numbers behave near tens and hundreds.
Getting to a rough answer quickly, which is a useful skill on its own and a good way to catch mistakes.
Looking at a sum and deciding which approach fits it, instead of applying one fixed method to everything.
Word problems and puzzles that ask children to apply what they have learned in a less predictable setting.
Four stages showing the shape of the journey. Your child’s actual starting point and pace are set after we see where they are — the four levels above are what the batches run to.
Everything rests on a child being genuinely comfortable with numbers. Number recognition, place value, counting forwards and backwards, and the idea that a number can be broken apart and put back together.
Children start doing real calculations without paper. Addition and subtraction with small numbers, using known facts and simple splitting, with accuracy prioritised over speed throughout.
More than one route becomes available, and the child begins choosing between them. Rounding and adjusting, doubling and halving, counting on, and estimating before calculating.
Larger numbers, multi-step problems, and word problems where the child must work out what is being asked before deciding how to calculate. Checking answers mentally becomes routine.
Suggested groupings, not fixed batches. Learning adapts to the child’s current level, so a younger child who is ready can start earlier and an older beginner still starts from the basics.
Number awareness & simple mental maths
The focus is comfort with numbers rather than speed. Counting, place value, number bonds, and simple addition and subtraction a child can do without writing.
Mental calculation & number strategies
Children secure with the basics learn splitting, rounding and adjusting, doubling and halving, and start choosing which strategy suits a given sum.
Advanced mental maths & problem solving
Larger numbers, estimation, multi-step word problems, and the habit of checking an answer mentally before accepting it.
Not sure where your child fits? That is what the free trial is for — we look at what your child is already comfortable with and suggest a sensible starting point.
What each one actually means, in plain language.
An instinct for how numbers behave — that 29 is nearly 30, and that this makes a subtraction easier.
Carrying a sum through to the answer in the head, without writing the working down.
Staying with a calculation from the first step to the last without losing the thread.
Getting the right answer consistently, and noticing when something looks wrong.
Working out what a question is asking before deciding how to calculate it.
Understanding why a strategy works, so it can be applied to a sum they have not seen before.
Reaching a sensible answer in a short time, built through practice rather than pressure.
Being willing to have a go — usually the change parents notice first.
Six stages, in the same order every time. Children settle quickly when they know what is coming next.
A short warm-up that revisits what was covered last time.
The new strategy is introduced, with the reasoning behind it explained.
A worked example on the board, taken slowly with questions invited.
Children work through sums together while support is close at hand.
A game, puzzle or challenge that uses the day’s strategy in a different setting.
A quick recap of what was learned and what to practise before the next session.
Examples of the kinds of activity used to keep practice varied. Children who enjoy the practice do more of it, and doing more of it is what makes the strategies stick.
Missing-number and pattern puzzles that ask children to reason backwards from an answer.
Short sets of sums against a gentle timer, so children can watch their own fluency build.
Paired and group games where the answer has to be worked out in the head, not written down.
Spotting what repeats in tables and sequences, which makes new facts easier to learn.
Guessing a rough answer first, then checking how close it was — useful and surprisingly fun.
Word problems and everyday situations where the child works out which strategy applies.
Brolly Juniors is a children’s learning centre at Nizampet X Roads, Hyderabad. Mental maths sits alongside our abacus, Vedic maths, chess, coding, robotics and AI programmes.
Everything is pitched at how children actually learn — short explanations, plenty of examples, and practice broken into pieces that hold attention.
Strategies are practised through games, puzzles and challenges rather than through worksheets alone.
Every strategy is explained in language a child can repeat back. If they cannot explain it, they have not learned it yet.
Topics build on each other in a deliberate order, and earlier work keeps being revisited as new material is added.
We tell you what your child is working on and what would help at home, in plain terms and without jargon.
Children are never pushed to be fast before they are reliable. Speed follows practice a child enjoys.
Parents ask this often, so it is worth answering plainly. Mental maths is the broader skill: calculating in the head using flexible strategies that work on almost any sum. Vedic maths is a specific set of shortcut techniques, each suited to a particular kind of problem.
Most children benefit from mental maths first. Once a child can hold a calculation in mind and choose between a few approaches, the Vedic shortcuts land much better — they become a faster route on ground the child already understands, rather than another rule to memorise.
If your child is already comfortable calculating mentally, they may be ready to start with Vedic maths instead. We will suggest which fits after the trial.
Not sure which suits your child? Book a trial and we will recommend one honestly, including saying if now is not the right time.
We share these directly rather than publishing them here, so what you get is current and specific to your child’s level.

Nothing before the trial
Let your child try the approach through simple, practical activities. The trial is a real session, not a sales meeting — your child works through an actual strategy, and you see how they respond to it.

You should not have to guess what your child is doing in class. Here is what you can expect to understand at any point.
Which strategies have been introduced, and roughly where your child is in the sequence.
Whether the current focus is learning a new strategy, building accuracy, or working faster.
The specific step your child hesitates on — usually something small and easily fixed at home.
Simple, short things you can do between sessions that reinforce rather than repeat the class.
Want an update on how your child is getting on? Ask. We will tell you honestly, including the parts that still need work.
Seven things that make a real difference between sessions, none of which require you to be good at maths yourself.
Five or ten minutes on most days beats an hour on Sunday. Short sessions stay enjoyable, and enjoyable practice is the kind that continues.
Card games, dice, dominoes — anything where children add or compare numbers quickly counts as practice.
“How did you work that out?” is the single most useful question. Explaining out loud shows whether the strategy is understood or only copied.
Shopping totals, change from a note, minutes until the bus, runs needed to win. Real numbers make the point better than a worksheet.
Notice the attempt, the persistence and the checking. That is what keeps a child trying the next question.
Timing every attempt makes children anxious rather than fast. Accuracy first; speed follows on its own.
Turn practice into a quick game or a challenge between the two of you. A child who associates maths with tension will avoid it.
Brolly Juniors runs its mental maths classes from a learning centre built around children rather than adult training. The room, the pace and the materials are all set up for young learners.
Parents across Hyderabad come to this for different reasons. Some have a child who can do the written method but stalls the moment the paper is taken away. Some want a younger child to build number confidence before school maths gets harder. Both work here, because children start from where they actually are rather than from a fixed syllabus point.
If you want to see the approach before committing, the free trial is the simplest way. Your child tries a strategy, you watch how they take to it, and we talk about a sensible starting point.

You are probably weighing two things: whether the centre is close enough to reach on a school night, and whether the teaching will suit your child. We are at Nizampet X Roads — and the second question is best answered by seeing a session rather than reading about one.
Mental maths pairs naturally with several others. Vedic maths and abacus reinforce the same number skills; chess and coding build the reasoning side.
Shortcut techniques for specific kinds of sum — the natural next step once mental calculation is comfortable.
🧮Bead-based calculation that builds visualisation alongside mental arithmetic.
🧩Broader thinking practice — memory, logic, patterns and strategy in short bursts.
♟️Planning, pattern recognition and thinking ahead — the reasoning that supports maths problem solving.
💻Logical sequencing and step-by-step thinking, built through projects children make themselves.
🤖Hands-on building and problem solving that puts logical thinking into a physical, visible form.

Short, direct answers to the questions parents ask most.
It gives children a method where they often have none, which builds number confidence. Everyday arithmetic takes less effort, and holding numbers in mind while working is genuine practice for focus and working memory.
Number recognition, mental addition and subtraction, multiplication and division, number patterns, estimation, calculation strategies and problem-solving activities.
The programme runs ages 7 to 14. Children can start once they recognise numbers and count confidently — the starting level comes from what they can already do.
Yes. Mental calculation is practised directly through games, puzzles and short challenges rather than left to develop on its own.
