Why Abacus way of Mental Arithmetic?
Mental arithmetic is a method of mental calculation performed using only the brain and without the help of any gadget like Paper, pencil, calculator or computer.
An arithmetic calculation performed by using the brain without the help of any gadget like paper, pencil, calculator or computer is know as mental arithmetic. In U C MAS, Mental Arithmetic is a method of mental calculation performed on a virtual image of an abacus, formed in mind. It is based on the principles of abacus calculation. Initially the child takes the help of the Abacus in calculation, over a period of regular training and practice they would be able to visualize the image of the abacus in their mind and perform mental calculation within few seconds without relying on any gadget or even the Abacus.
Today, a child is able to read and form words/sentences and even write them before being able to add, subtract, multiply or divide. The complications involved in learning arithmetic compared to learning alphabet,
For example, when you form a sentence, you can imagine in your mind what you say in that sentence, however when you add or subtract, you have to write it down because it is hard to visualise the numbers. This is because, “Letters are generally introduced with pictures or images, for example: ‘A’ denotes apple. The same applies to words or sentences, which can be taught in pictures, whereas it’s quite hard to give image representation for numbers, especially above ten. “If the child can visualise numbers just as they do letters, then mental maths can be made easier.
Many people often assume that learning mental arithmetic is merely a method to improve the speed and accuracy of calculations, for example, adding 10-digit numbers within a few seconds.
By itself, it is an amazing accomplishment for most young children. However, there is more to this because when the children are learning U C MAS Mental Arithmetic, they are actually also undergoing the process developing other aspects of the mind. When the children have acquired an astonishing calculation speed, it is actually only the end result of having developed the following mental abilities: concentration, observation, visualization & imagination, and memory
