Abacus is a tool to perform basic mathematical operations like addition, subtraction, multiplication, and division. The tool contains one horizontal bar and usually 13 or 17 vertical rods with movable beads. Each vertical rod has one bead of value five above the horizontal bar and four beads of value one each below the horizontal bar.
This is known as Soroban in Japan and taught in primary schools due to the advantages of its learning. In the initial stages, calculations are performed on the physical Abacus. However, the usage of the Abacus gradually ceases and the user is able to visualize the Abacus in his mind and solve mathematical calculations mentally fast and accurately.
Brief History
- The Sumerian abacus was the first to appear in 2700-2300 BC in history.
- Chinese abacus known as the suanpan dates back to the 2nd century BC. it has 2 beads above and 5 beads below the horizontal bar.
- Japanese abacus known as the Soroban came from China in the 14th century. It has 1 bead above and 4 beads below the bar.
- In Korea, Abacus is called jupan, supan or jusan. It came from China around 1400 AD.
Benefits of Learning
High Calculation Speed with Accuracy
This is the direct benefit of learning Abacus. Performing Mathematical calculations with speed & accuracy help in performing well in exams. Time saved can be used in solving other problems.
Makes mathematics an interesting subject
We all know that generally kids do not like maths. Many of them even have Maths-Phobia. Teaching abacus is the best way to make maths an interesting subject because once kids start doing mental calculations they fall in love with this subject.
Develops Power to Concentrate
Everyone knows that to get great results in studies focus is mandatory. The more the concentration, the better are the results. Concentration power doesn’t come automatically, this needs to be developed over a period of time. Abacus exercises help a lot in this regard. Students not only become fluent in the mathematical calculation but also improve their concentration power which helps them to do better in all the subjects.
Develops Observation & Visualization Power
When we observe things well, we are able to remember, visualize & analyze them in a better way. Abacus exercises help students to improve their observation skills. They become capable of analyzing all aspects of a situation and thus become more alert and fast in their responses.
Develops Memory Power
Development in all above abilities i.e., the power to focus, the power to observe & the power of imagination leads to a great memory. Performing abacus exercises with the help of visualization of the abacus does wonders in calculations. One can do additions, subtractions, multiplication, and division of even large numbers in seconds.
Develops Confidence and Self-esteem
One who has confidence has the power to do things with great results. Students gain a lot of confidence when they learn the abacus. The reason being, when they do calculations with great speed and accuracy in school, they get appreciated. This appreciation boosts great confidence in them. They get motivated to do better in all fields.
