Learn the Japanese abacus, then do the math in your head. Soroban Path teaches the soroban step by step. Every lesson starts with a short demonstration. Then guided beads show exactly where to move, and you try it yourself, with hints ready whenever you need them. Little by little the beads turn into a picture in your mind. That picture is why soroban students are so quick at mental math. MEET THE COMPLEMENTS When a sum does not fit on the beads, a complement steps in: the number that makes 5 or 10 together with it. Soroban Path teaches all 34 complement formulas - 5-complements, 10-complements and the mixed ones - and, just as important, when and why each one is needed. Knowing the reason is what turns memorized moves into real number sense. HOW IT WORKS - 46 short lessons in 10 units, from "Meet the Soroban" to "Mental Math & Flash" - Watch, follow the arrows, then try it on your own, with three levels of hints - Review that brings each complement formula back at just the right time, and a star for every one you know well - Already know some soroban? Take a short test and skip ahead - Four kinds of practice: Bead Drills, Soroban Sums, Flash Anzan and Listening Math - Instructions are read aloud, and one tap in any lesson turns the voice off when you need quiet - A weekly practice goal, with no lives, no penalties and no leaderboards - Certificates for finished units, and a progress report you can share FREE TO START The first 12 lessons and a starter set of practice levels are free, so you can try the whole way of learning before you buy anything.
