Parents often hear impressive promises about the soroban: super memory, higher IQ, genius-level maths. The reality is more modest — and more useful. The Japanese abacus gives children a concrete, visual model of numbers that makes arithmetic easier to understand and practise. Used regularly, it supports skills that matter every day in primary school maths.
Below are the seven most practical benefits of soroban for children, what you can expect to see, and a quick activity for each. We also summarise what research does and does not support, so you can set realistic goals.
1. Place value becomes visible
On paper, 24 and 42 use the same digits. On a soroban, they look completely different: two beads on the tens rod and four on the ones rod, or the reverse. Children see that a digit’s value depends on its position — the idea behind every written calculation.
Try this: show 24, then 42, and ask “What changed?”. Next show 105 and talk about the empty tens rod. Zero stops being “nothing” and becomes a place holder.
2. Stronger number sense with 5 and 10
The soroban is built around 5 and 10. To calculate, children constantly use the pairs that make 5 (1 + 4, 2 + 3) and 10 (1 + 9, 2 + 8 …). These pairs, often called “friends of 5” and “friends of 10”, are the same number facts that support mental strategies such as 8 + 5 = 8 + 2 + 3.
Try this: on a rod showing 4, ask the child to add 3. They will need to add 5 and remove 2. Ask them to explain why the answer, 7, is correct. Our guide to friends of 5 and 10 covers all cases.
3. Accurate and fluent arithmetic
Soroban gives children one consistent method for addition and subtraction, then for multiplication and division. Because every step is visible, mistakes are easy to locate and correct. Over time, accuracy turns into fluency: children stop counting on their fingers and start recognising patterns.
This is the benefit with the strongest evidence. In a three-year randomised trial with about 200 children in India, mental-abacus instruction led to better arithmetic results than standard extra maths lessons (Barner et al., 2016).
Try this: do three untimed problems — 2 + 1, 6 − 1, 12 + 3 — and check each one together before adding more.
4. A path to mental calculation (anzan)
After enough practice, many children begin to imagine the beads and calculate without the tool. Studies show that trained users really do hold numbers as visual images rather than words (Frank & Barner, 2012). For a child, being able to “see” 37 + 25 in their head is motivating and practical.
Try this: once your child reads bead patterns quickly, ask them to close their eyes, picture 6 on the abacus, then add 2. Check on the real soroban. Read more in when and how to introduce anzan.
5. Practice that trains focus
A soroban session demands attention: listening to numbers, moving the right beads, keeping track of place value. Short, structured practice gives children a regular experience of sustained focus on one task, which many parents and teachers notice.
A note of honesty: research has not shown that abacus training improves attention in general, outside maths. Treat better focus during practice as a welcome side effect, not a guaranteed outcome. Our article on focus, memory and confidence looks at this in detail.
6. Fine motor skills for younger children
Moving one bead with the thumb and another with the index finger requires precise, controlled finger movements. For 5- and 6-year-olds, this coordination is a useful bonus, much like threading beads or using scissors.
Try this: practise “thumb up, index down” on one rod, slowly, ten times. Precision first, speed later.
7. Confidence through visible progress
Soroban progress is easy to see: yesterday the child needed hints for 4 + 3, today they do it alone. These small, concrete successes can make maths feel achievable, especially for children who think they are “bad at maths”.
Try this: record one simple measure each week, such as correct answers out of ten. Praise the method (“you used the friend of 5”) rather than speed. Confidence grows from success, not pressure.
What research supports — and what it does not
To set realistic expectations, here is how strong the evidence is for each benefit:
| Benefit | What you may see | Evidence |
|---|---|---|
| Arithmetic accuracy and fluency | Faster, more reliable calculation | Supported by a randomised trial |
| Visual mental calculation | Child calculates by imagining beads | Supported by laboratory studies |
| Place value and number sense | Fewer place-value errors | Strong teaching rationale |
| Focus during practice | Longer attention on one task | Observation; general transfer not shown |
| Fine motor control | More precise finger movements | Observation |
| Confidence in maths | More willingness to try | Observation; depends on teaching style |
| Higher IQ or “photographic memory” | — | Not supported |
The same 2016 trial found that gains were largest for children who started with stronger spatial working memory, and it found no improvement in basic cognitive abilities. That is why we recommend soroban as an excellent arithmetic tool, not as a brain-training programme.
How to get these benefits
The benefits come from regular, well-structured practice rather than long sessions. Five to ten minutes on most days is a good rhythm for beginners.
- Start with showing numbers on the free virtual soroban.
- Follow the beginner learning path, one rule at a time.
- Reinforce with exercises and printable worksheets.
- Keep accuracy first; add timed training only when a skill feels easy.
Conclusion
The real benefits of soroban for children are concrete: visible place value, strong number combinations, accurate arithmetic and, for many, the ability to calculate mentally. Focus, fine motor skills and confidence often grow along the way. Keep expectations realistic, keep sessions short and regular, and the soroban can become one of the most enjoyable parts of your child’s maths learning.

Questions from parents
What are the main benefits of soroban for kids?
Better understanding of place value, solid number facts around 5 and 10, accurate arithmetic and a gradual path to mental calculation. Focus and confidence often improve during practice.
Does soroban increase IQ?
No reliable study shows that. A large randomised trial found better arithmetic but no change in basic cognitive abilities.
How long before we see benefits?
Many children read numbers confidently within a few weeks of short daily practice. Fluent calculation with friends of 5 and 10 usually takes several months.
Should my child practise for speed first?
No. Start with accurate bead movements and an explanation of the answer. Add timed practice when the child can complete that type of question comfortably.
Does soroban replace school maths?
No. It is a tool for arithmetic. Children still need word problems, measurement, geometry and other ways of reasoning about numbers.
