ABACUS, also called a counting frame, is a calculating tool which was used before the numeral system was discovered. It provides countable beads for children to visualize numbers. Children manipulate those beads to perform Arithmetic calculations mentally.The calculations will be of great speed in this way. The program develops the integrated and motoring functions from both sides of the brain. When children manipulates the beads of the abacus, communication between the hands and the brain stimulates the right and left hemisphere of the brain. The right side – the abstract side creates an image memory of the beads on the abacus while the left side the logical side applies the requisite rules to perform the calculations. When both sides of the brain are  activated it ignites cognitive firestorm in students providing better focus and concentration coupled with creativity and memory.
