Parents often notice that their child sits more calmly, remembers numbers better and approaches maths with more confidence after some months of soroban. These changes are real experiences for many families. But it is worth understanding how they happen — and where the evidence stops — to get the most out of practice.
This article explains what soroban practice asks of a child’s attention, memory and self-confidence, offers activities that train each one, and summarises what research shows.
Focus: what happens during a soroban session
Even a simple problem like 34 + 25 requires several things at once: listening to the numbers, locating the right rods, choosing the correct bead movement and checking the result. If attention drifts for a second, the answer is wrong — and the child sees it immediately on the abacus.
This instant feedback makes soroban a good context for practising sustained attention on one task. Sessions of 5 to 10 minutes are long enough to require focus, and short enough to finish while concentration is still good.
- Listening drill: read out three or four numbers to add, at a steady pace. The child sets each one without seeing it written.
- “Spot the bead” game: show a number for two seconds, hide the abacus and ask the child to set the same number.
- Single-task timer: a 5-minute block with no interruptions, phone away, just the abacus.
Memory: holding numbers as images
Working memory is our ability to hold and manipulate information for a short time — for example, remembering a running total. In soroban, the beads carry part of this load at first: the total is always visible. Later, during anzan (mental calculation), children learn to picture the beads and update the image in their heads.
Researchers have shown that experienced mental-abacus users represent numbers visually rather than in words: they are less disturbed by verbal distractions and make errors that resemble misplaced beads (Frank & Barner, 2012). In other words, the soroban gives children a powerful visual code for numbers.
- Flash numbers: show a two-digit number for one second, then a three-digit number as the child improves. The child sets it from memory.
- Picture and check: the child closes their eyes, imagines 7 on the abacus, adds 2 mentally, then checks on the real soroban.
- Chain addition: add three single-digit numbers mentally, then check.
Confidence: progress you can see
Children who find maths hard often feel that numbers are abstract and unpredictable. On the soroban, every step is concrete and every rule can be checked. When a child solves 4 + 3 alone after needing help the day before, they have clear proof of their own progress.
This kind of confidence grows only if practice is well paced. Problems should be challenging but mostly successful — around 8 or 9 correct answers out of 10 — and adults should praise strategies rather than speed.
- Keep a progress chart with one simple measure per week.
- Let the child explain a problem to a parent or sibling.
- End every session with a problem the child can solve.
What research says — and what it does not
The best-known randomised trial, conducted over three years in India, found that children who learned mental abacus improved more in arithmetic than children receiving extra standard maths lessons. However, it found no improvement in basic cognitive abilities such as working memory or general reasoning (Barner et al., 2016).
In practice, this means: soroban develops focus and memory for numbers within maths practice, and many children show more calm and confidence during these activities. Claims that it boosts attention or memory in every area of life, or produces a “photographic memory”, are not supported by current evidence.
| Area | What you can expect | What is not proven |
|---|---|---|
| Focus | Longer, calmer attention during practice | Better attention in all school subjects |
| Memory | Visual images of numbers, mental calculation | General memory improvement |
| Confidence | More willingness to try maths problems | Confidence without good pacing and support |
A 10-minute session that trains all three
You can combine these activities in a single short session:
- 1 minute: clear the soroban and sit calmly.
- 2 minutes: listening drill with five numbers.
- 3 minutes: today’s calculation rule (for example friends of 5 and 10).
- 2 minutes: flash numbers or picture-and-check.
- 2 minutes: the child explains one problem and records the day’s score.
The training mode is useful for flash numbers, and the learning path structures the calculation rules.
Conclusion
Soroban asks children to focus, hold numbers in mind and act precisely, and it shows progress clearly. That is why many families see better concentration, stronger memory for numbers and more confidence during maths practice. Keep sessions short and successful, use activities that target each skill, and keep expectations grounded in what research supports.

Frequently asked questions
Does soroban improve concentration?
Practice requires sustained attention and gives instant feedback, so many children focus better during sessions. Research has not shown a general improvement in attention outside maths.
Does soroban improve memory?
It trains memory for numbers: advanced learners hold numbers as images of beads. A large trial did not find improvements in general working memory.
How does soroban build confidence?
Each step is visible and checkable, so children see their own progress. Confidence grows when problems are mostly successful and adults praise strategies.
How long before we notice changes?
Many parents notice calmer, more focused practice within a few weeks of short daily sessions. Mental calculation skills take several months.
