iPhone Giveaway of the Day - Abacus in Augmented Reality

*This app is designed to be as close to real wooden school abacus as the latest achievements in technology (augmented reality) would let us.
**The beads move as you shift your iPad making sounds as they touch one another.
***The ‘transparent’ background gives you a feeling as if you were holding the actual handheld abacus.

Abacus (or soroban) helps a learner develop ability to do the arithmetic calculations MENTALLY. The learner converts the numbers into beads, manipulates the beads, and brings out the result.

It enables learners to
1) understand the basic number systems;
2) understand concepts of carrying and borrowing in arithmetic;
3) understand combinations of 5 and 10 and complements of numbers;
4) visualize close relations between numbers and numerals, and
5) develop learners’ ability to perform mental calculations.
