When children learn mathematics, the goal should go beyond getting the correct answer.
Mathematics can help children develop the ability to think, analyse, concentrate, make decisions, and solve problems. One of the ways children can strengthen these abilities is through mental math—the ability to perform calculations in the mind without depending entirely on paper, calculators, or other tools.
For parents looking for ways to support their children’s academic development, building strong mental math skills for children can be a valuable part of their learning journey.
What Is Mental Math?
Mental math is the process of performing mathematical calculations using the mind.
Instead of immediately writing down a calculation such as:
27 + 18 = ?
a child with developing mental calculation skills may mentally break the numbers apart:
27 + 10 = 37
37 + 8 = 45
The child arrives at the answer while keeping the calculation in their mind.
With regular practice, children can become more comfortable working with numbers, recognising patterns, and choosing efficient ways to solve mathematical problems.
How Mental Math Develops Problem-Solving Skills
Problem-solving is not limited to mathematics. Children encounter problems every day at school, at home, and in social situations.
Mental math encourages children to approach a question by thinking about what they already know, what they need to find, and which method might work best.
For example, when faced with a mathematical problem, a child may learn to:
- Break a large problem into smaller parts.
- Identify useful information.
- Look for patterns.
- Compare different approaches.
- Check whether an answer makes sense.
- Adjust their approach when necessary.
These habits can contribute to stronger problem-solving skills for kids both inside and outside the classroom.
1. It Encourages Faster Thinking
Mental calculation requires children to process numbers and information actively.
With consistent practice, familiar calculations can become easier to recognise and solve. Instead of spending excessive time on simple calculations, children can focus more attention on understanding the larger problem.
This doesn’t mean that children should simply rush through mathematics. The goal is to develop speed together with accuracy and understanding.
2. It Strengthens Concentration
Mental math requires a child to keep information in mind while working through a calculation.
For example, solving a multi-step calculation mentally may require the child to remember an earlier result while performing the next step.
This kind of activity encourages children to maintain attention and resist distractions.
Over time, structured mathematical exercises can help develop better concentration and mental discipline.
3. It Supports Working Memory
Working memory allows us to temporarily hold and use information while completing a task.
Mental calculation naturally engages this ability.
A child might need to remember a number, perform another calculation, and then combine the results. Repeated practice gives children opportunities to exercise these mental processes.
This is one reason mental math and children’s cognitive development are often discussed together.
4. It Helps Children Recognise Number Patterns
Strong mental mathematicians don’t necessarily calculate every problem from scratch.
They begin to recognise relationships between numbers.
For example, a child may notice that:
49 + 26
can be approached as:
50 + 25 = 75
Recognising relationships like this can make calculations more efficient.
The child is not simply memorising an answer. They are learning to look at numbers differently and find useful connections.
5. It Builds Mathematical Confidence
Some children become anxious when they see numbers or complicated mathematical questions.
Regular mental math practice can help make numbers feel more familiar.
As children successfully solve increasingly challenging problems, they may begin to develop the confidence to attempt questions they would previously have avoided.
That confidence can be particularly valuable when children encounter more complex mathematics at school.
6. It Encourages Children to Think Before Reaching for a Calculator
Calculators are extremely useful tools, but children also need opportunities to develop their own number sense.
When children regularly practise mental calculation, they become more comfortable estimating, calculating, and checking answers independently.
For example, if a calculator produces an unexpected answer, a child with good number sense may recognise that something doesn’t look right.
Mental math therefore isn’t about replacing calculators. It is about helping children develop the underlying skills needed to understand and work confidently with numbers.
How Abacus Training Can Support Mental Math
One approach used to develop children’s mental calculation skills is abacus training.
An abacus gives children a physical representation of numbers. As they practise calculations, they learn to manipulate the beads and gradually develop an understanding of numerical relationships.
With continued training, some programmes introduce mental visualisation, where children learn to imagine the abacus and perform calculations mentally.
This progression can help connect physical calculation with mental calculation.
The SIMA Abacus Approach
At SIMA Abacus, children are introduced to Abacus-based learning designed to develop more than calculation ability.
Through structured practice, children have opportunities to develop skills such as:
🧠 Concentration – staying focused on a task.
🎯 Accuracy – working carefully to reach the correct answer.
⚡ Mental calculation – performing calculations with increasing confidence and efficiency.
👁️ Visualisation – developing the ability to mentally represent numbers and calculations.
💡 Problem-solving – learning to approach mathematical challenges systematically.
The objective is not simply to make children faster at arithmetic. It is to help them develop a stronger and more confident relationship with numbers.
Mental Math Is a Skill That Develops With Practice
Children don’t have to be naturally gifted at mathematics to develop strong mental math abilities.
Like many other skills, mental calculation improves with consistent, age-appropriate practice and encouragement.
Parents can support this development by incorporating simple mathematical activities into everyday life.
For example, you can ask your child:
- “If we have 12 apples and buy 8 more, how many do we have?”
- “What is 50 minus 17?”
- “Which is greater: 38 or 83?”
- “If three people share 15 items equally, how many does each person get?”
- “Can you find another way to solve this problem?”
The objective is to make thinking about numbers a natural part of everyday life.
The Bigger Picture: Teaching Children How to Think
One of the most valuable outcomes of mathematics education is not simply knowing how to calculate.
It is learning how to approach a problem.
Mental math gives children regular opportunities to practise concentration, reasoning, memory, number sense, and decision-making.
When these skills are developed together, children can become more comfortable approaching challenges that require them to think carefully rather than immediately giving up.
Final Thoughts
Developing mental math skills for children can provide benefits that extend beyond arithmetic.
Through mental calculation and structured activities such as abacus training, children can practise concentration, visualisation, number sense, problem-solving, and mathematical confidence.
Every calculation becomes an opportunity to think.
And every opportunity to think can help a child become a more confident learner.

Frequently Asked Questions
At what age can children start learning mental math?
Children can begin developing basic number and mental calculation skills from an early age, with activities adapted to their age and level of development.
Is mental math difficult for children?
It can be challenging at first, but regular, structured practice can make calculations increasingly familiar and manageable.
Does abacus training improve mental calculation?
Abacus training can provide children with a structured way to practise numerical operations, and programmes that incorporate mental visualisation can help children develop mental calculation skills.
Can mental math help with problem-solving?
Yes. Mental math activities require children to process information, recognise patterns, make calculations, and choose strategies—all of which are useful components of mathematical problem-solving.
Is mental math better than using a calculator?
They serve different purposes. Mental math develops number sense and independent calculation skills, while calculators are useful for more complex or time-consuming calculations. Children can benefit from knowing when and how to use both.
