Abacus Soroban Math Worksheets and Soroban Math Lessons

The soroban is an abacus developed in Japan. It is derived from the Chinese suanpan, imported to Japan in .
the 14th century. The soroban uses a decimal system, where each of the rods can represent a single digit from 0 to 9. By moving beads towards the reckoning bar, they are put in the "on" position; i.e., they assume value. For the "five bead" this means it is moved downwards, while "one beads" are moved upwards. In this manner, all digits from 0 to 9 can be represented by different configurations of beads.
