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 rulesFour 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.
By format
The same arithmetic delivered differently — flashed, spoken, timed, or printed on paper for a session away from a screen.

The placement exam takes about five minutes and recommends a level. It is free and needs no account either.
