A Soroban is a Japanese abacus, which can help children to understand number concepts and visually demonstrates the decimal system. There are only five beads in each column, with the top bead having a value of 5 and the four lower beads each having a value of 1. Either tap or slide a bead to show its value and when you are finished, shake the iPad to reset all the beads to zero.
