One 45 minute Soroban classes (Japanese Abacus).

A Mental Computation System – Not “Math Facts” or Tricks

As a manipulative tool, the Soroban brings numbers to life. In addition to using the beads to represent numbers, the students perform computations by moving the beads up and down. Instead of merely memorizing an answer, the children are active participants in the process, and therefore have control of the steps involved in performing arithmetic.
