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.

Test your maths skills and reflexes in the abacus maths challenge. Your score for each question is the amount of time left on the clock, so speed is important. Watch out for minus questions, as things get steadily harder.
