ABACUS
From the history of abacus, it is known that during the 11th century, the Chinese abacus or suan pan, was invented. A suan pan is a frame having a horizontal divider, who divides the frame into two parts, above the divider is called upper part and below the divider is called lower part. In the Chinese abacus, there are two beads in the upper part and five beads in the lower part. During the last part of the 15th century, use of the Chinese abacus or suan pan spread to Korea, and then to Japan. Soroban is the Japanese termed of abacus. Originally the soroban looked like Chinese abacus having two beads in the upper part and five beads in lower part. In the year 1850, it was modified to have only one bead in the upper part and no change in the lower part (5 beads). In the year 1930, it was again modified that to have one bead in the upper part and four beads in the lower part. In the year1979, the Chinese Abacus Association was founded. They established a graded examination in 1984, and started competitions in 1989. It is felt by many abacus experts that learning abacus strengthens the student’s sense of number placement value and helps to further a better overall understanding of numbers. It’s also a lot of fun.
Why ABACUS
In this competitive era, every kid needs a proper direction to dig out their hidden potential from himself to be the best. Every parents hope that their children should be the best among others. In support with your view, abacus training is one of the best training to make your child brainy, talent, master mind. This training gives confidence to face competition exams. A slow brainy student also able to show performance more than earlier. Over all, to be the best, the basic needs are- master-mind, memory, concentration and confidence : and all is included with abacus training.
Construction of Abacus (Soroban).
Abacus (Soroban) is a counting instrument with beads on rods in a frame. The frame is divided into two parts by a horizontal beam called divider. The two parts of the abacus are known as “upper part” and “lower part”. One bead in the upper part is valued five and each beads in the lower part is valued one. Each rod represents a digit such as ‘Ones’, ‘Tens’, ‘Hundreds’, ‘Thousands’ etc. The number of rods in a Soroban is always odd and never less than nine. Basic models usually have thirteen rods, but the number of rods on practical or standard models often increases to 21, 23, 27 or even 31, for calculation of more digits or representations of several different numbers at the same time. A soroban contains some dot marking in every third rod to designated last digit of the whole number, that is called unit rod. The right part of the unit rod is to calculate decimal number. The unit rod is always designated as 1’s, immidiate left rod is designated as 10’s, next immidiate left rod is designated as 100’s, then thousands, millions, etc.
Our method of training :
Our method of training is Japanese Abacus (Soroban) and use a modern 1 : 4 bead Japanese soroban. Always Work from Left to Right : The technique to use the abacus is "always work from left to right". The students may feel hesitation in first time that habitually they are doing sums from right to left but after regular practice, new students also can solve arithmetical problems easily without hesitation. We can solve mathematical problems with great agility and speed.
The benefits of learning ABACUS
Basic mathematical operations like addition, subtraction, multiplication and division are solved by simple movement of beads in this instrument. This helps the student to develop a pictorial representation of the problem in the brain and by regular practice, the brain learns to solve the problem without actual use of any aid including the abacus. The students thereby develop an exciting photographic memory.
Arithmetical tool is ABACUS :
Nowadays, many of the Educational Institutions around the world are incorporating Abacus in their regular syllabus with the aim of sharpening the basic mathematical skills in students. Extensive research on the subject has consistently proved that regular practice in Abacus results in a more proficient and sharper brain.
Brain exercise tool is ABACUS :
Like any other organ of human body, our brain also needs regular exercise to keep it fit and sharp but how do we exercise our brain ? Mathematics provides the ideal exercise for our brain. Mathematics is the logical application of mind to tackle a particular problem. More time spent with mathematics would invariably result in a well exercised and a sharper brain. This is simply the reason why a child strong at mathematics is able to tackle other subjects with relative ease.
Mathematics fun is ABACUS :
But most children fear mathematics and often try to escape from the complexities of problem solving. This is where Abacus comes to aid. Abacus develops speed and accuracy in mathematics using very basic methods. This naturally develops aptitude and liking for Mathematics within a very short period.
Necessity of learning ABACUS :
With the growing of technology, most of the children are depending on calculators to solve even basic mathematical problems. On being dependent on electronic calculator, they are ignoring the opportunity that to solve arithmetical calculation mentally or using mental calculator, as a result, it is naturally denied to make our brain sharpen.
Benefit of learning ABACUS :
Children who learn the abacus generally achieve higher academic performance not only in arithmetic but also in all subjects because of the concentration. Abacus training increase concentration. Abacus training gives ability to solve arithmetical problem once looking at a problem and working it out mentally. On solving arithmetical problem mentally, children become proud on his capacity, grow their confidence, dare to challenge with others, try to make himself all-rounder and be successful in all areas.
