  • Bead reading race
    L0 number-reading 6 min

    This is a race-style exercise: the goal is not panic, but faster clean reading of a two-rod number.

  • Identify the bead groups
    L0 abacus-orientation 4 min

    The first step in reading a soroban is understanding the value of the two bead groups on a rod.

  • Name the beam and active position
    L0 abacus-orientation 3 min

    Value depends on contact with the beam, not just on bead position somewhere on the rod.
