By technique
One page per step of the nine-level soroban curriculum, from first bead to division. Follow them in order if you are learning the method properly.
🧮Abacus counting practice: 1 to 10The first thing a child does on a soroban: make each number from 1 to 10 with the beads, then add two of them together.Practise →➕One-digit addition and subtraction drillsThree single digits stacked in a column, added and subtracted straight on the beads — no complement rules, no borrowing.Practise →🤝Small friends practice: the 5-complement rulesTwo pairs to learn — 1 and 4, 2 and 3 — and suddenly every single-digit sum works, even when the bead you want is already up.Practise →🔟Big friends practice: the 10-complement rulesThe carry, done the abacus way: when a digit will not fit on its rod, take ten from the rod to its left and give back the difference.Practise →📚Multi-row addition practice (10 rows)Ten numbers, one column, no pauses. This is where accuracy stops being about knowing the rules and starts being about not losing concentration.Practise →🧠Three-digit mental math practiceThe abacus goes away and the image stays. Three-digit columns worked entirely on a soroban the learner can only see.Practise →✖️Soroban multiplication practiceMultiplication on the soroban is addition with bookkeeping — the times table you already know, placed on the right rods.Practise →🚀Multi-digit multiplication practice (3 × 2)Six partial products, no scratch paper, nothing written down — the point at which abacus multiplication overtakes the written algorithm outright.Practise →➗Soroban division practiceThe last technique in the ladder: place the dividend, subtract multiples of the divisor, and read the quotient off the rods it left behind.Practise →
By problem width
Straight arithmetic drills sorted by digits and rows. Use these when you know exactly what you want to practise and do not need the curriculum framing.
1️⃣One-digit addition drillsFive single digits per column. Short enough for a five-year-old, long enough that memorised answers stop working.Practise →2️⃣Two-digit addition drillsTwo rods, five rows, and carries that have to happen the moment they occur — the width where abacus method starts beating pencil and paper.Practise →3️⃣Three-digit addition drillsThree digits and chained carries — where a carry into the tens can push another one straight into the hundreds.Practise →➖Soroban subtraction drills (2 digits)Subtraction is where abacus learners lose the most marks — the complements run backwards and the borrow travels the other way.Practise →🔀Mixed addition and subtraction drillsSigns that change without warning, so there is no rhythm to settle into and no shortcut to fall back on.Practise →🔟Ten-row addition drillsThe classic exam column: ten numbers, one answer, and no way to check your work partway through.Practise →
By format
The same arithmetic delivered differently — flashed, spoken, timed, or printed on paper for a session away from a screen.
⚡Abacus flash cardsNumbers appear one at a time and vanish. Nothing stays on screen, so nothing can be re-read — the total lives in your head or nowhere.Practise →⏱️Mental math speed testTwelve problems, one clock, one score. A benchmark you can repeat weekly to see whether practice is actually moving anything.Practise →🎧Listening mental math practiceNothing on screen. The numbers are spoken, the abacus is imagined, and the answer is said out loud.Practise →🖨️Printable abacus worksheetsGenerate a worksheet, print it, and practise away from a screen — with a matching answer key for whoever is marking.Practise →🧠Mental math test for adultsTwelve problems sized for adult brains — three digits, five rows, no mercy. Take it cold, note your time, and see what a few weeks of practice does to it.Practise →🔢Math facts practiceFact fluency is automaticity — answering 7 + 6 without counting. This drill serves the facts one at a time and tells you instantly whether the recall is there yet.Practise →✖️Times tables speed testSample table problems with answers below, and the abacus route to multiplication in the free app. On the nine-level ladder, soroban multiplication starts at Level 7.Practise →
