Skill Development Program with Abacus

The abacus is a beaded instrument. Which has been used for the purpose of calculations for the last 2000 years.

The abacus consists of beads and each row consists of 5 beads. The calculations are doneby moving the beads up and down. The speed and accuracy of calculations vary from person to person and be further fine-tuned through continuous practice.

How to abacus help you?
  • Before the invention of a calculator it would have been really difficult to do sums for archeology, experiments or for mere business purposes. In the earlier days a man's hands and the pebbles used to be the counting device and there were no numerals. It was in this context that the abacus and the counting tables were born.The abacus is the olden form of our calculator, its origins dates back to 2400 BC when the Babylonians used pebbles and dust abacus for their calculations.

  • The abacus and the counting boards were the aids which were used to ease the calculations. In no way it can be compared with the calculators that we use today.

  • While using these aids the person is actually doing the calculation on his mind, the abacus is only helping him keep a track of his calculations; which make the mental calculations much easier.

Mental Arithmatic

There are a myriad of other reasons, from being able to dazzle one's friends and future coworkers to giving one confidence about their abilities. After all, thinking is what makes us human-not dependence on machines to do our thinking for us!

The aim of many mental maths’s training is to teach the child not to rely very much on calculators and any other electronic gadgets that are used for calculating. Using your brain cannot compete with any machine in the world.

Why Is Mental Math Important?
  • Mental math, irrelevant of its applications, is an excellent way to stimulate one's mind. Not only does it generally stimulate your mind, but it also helps one get a better "number sense." In other words, one becomes more familiar with how numbers interact--this is very important, because as you know, math is something that builds on itself.

  • If you don't have a good grasp on how numbers interact, then more complicated math will seem like more of a challenge. If you can't add and subtract without the help of a calculator, it can certainly reflect poorly on you.

  • While using these aids the person is actually doing the calculation on his mind, the abacus is only helping him keep a track of his calculations; which make the mental calculations much easier.

  • Even if you really are a very intelligent person otherwise, this inability may give people a different idea. For better or for worse, our society puts a lot of stock into appearances. If one doesn't appear to be educated or "smart" at first glance, society will often just label that person as such.

  • Also, the fact is that calculators are most useful in a setting that requires either:
  • things that are essentially impossible for humans to compute at any reasonable speed (like evaluating the cosine of a number or

  • for calculations with rather large numbers. For two digit addition, not using a calculator should actually be faster, given that you have learned the techniques well.

  • There are a myriad of other reasons, from being able to dazzle one's friends and future coworkers to giving one confidence about their abilities. After all, thinking is what makes us human--not dependence on machines to do our thinking for us!

  • In the modern world of computers and calculators, mental estimation skills are MORE important, rather than less! That's because, although Calculators and cash registers make it unnecessary to do exact calculations in many instances, it can be easy to trust them too much. People can make mistakes in using them, entering the wrong amount or doing the wrong thing with it, and if we just blindly accept the answer it gives without checking, we'll lose out a lot.

  • One major kind of error is putting the decimal in the wrong place (or failing to enter it at all), another is to miss a key so that what should have been 1234 is taken as 124, off by a factor of ten! Or how about hitting "percent" instead of "divide"! These kinds of mistakes are easily caught by estimating the correct answer. Estimation won’t catch errors of pennies, but it will catch dollars, which are more important anyway.

  • You can probably find other Examples where this will be important in her life, but money is a good motivator! It's worth noting that estimation uses the same skills as exact mental arithmetic, and more. It also builds number sense by making you aware of what matters most. A teacher who says arithmetic skills are unimportant is depriving students of an essential life skill.
