Difference Between Abacus And Soroban

Regular academics get fascinating when distinct manipulatives are employed in pedagogies. Math is one such subject where pupils can employ estimators. Abacus is one such handy reckoner that has attained universality. In View of after-school programs, the abacus has a set of edges and catches too. Does the implementation of Soroban mitigate these? 

While the traditional abacus has a Chinese origin, Soroban is merely a Japanese version derived from it. We will inculcate you with pivotal contrasting traits between Abacus and Soroban, easing you to make a stronger choice among these. 

Abacus- Insights to comprehend

With a history of around 5000 years, Abacus has been in use by several countries. Derived from a greek work Abacon— Abacus means table, Tablet, or a flat surface. Romans and Greeks are believed to use Abacus type devices. However, historians claim that Chinese minds introduced these at around 500 B.C.Soon countries like Malaysia, Korea, Taiwan, and Japan began operating them, which gave rise to a wide variety of styles, and sizes. The base concept of beads and rods is retained in all these variants. 

Grasping varieties of abacus

The World has witnessed a wide variety of Abacus as time passed. Comprehending these, in brief, can make you intelligible. Ancient Roman Hand Abacus is Probably the oldest version of the abacus; these contain seven long and short grooves. While the upper grooves have one bead, the lower ones have four beads. Later Chinese Suanpan Abacus was developed based on Hindu-Arabic mathematics in the twelfth century. These are often made with Hardwood having a length of about 20cm. It has 2 beads in the upper deck and 5 beads in the lower. Known in multiple names, Suanpan was designed to make calculations with precision.

The East Asian Schoty Abacus has been a popular reckoner in Russia for centuries. While other variants have horizontal configuration, Schotys have a vertical configuration. This model is sparsely used in basic calculations probably because it cannot stand up with other versions. Vietnamese Abacus takes a unique place by having five beads on upper and lower decks. Since only bookkeepers used it in Vietnam, it gradually lost its existence. 

Soroban Abacus is a Japanese simplified category with just a 1:5 configuration.  Lee’s Improved Abacus is the latest model created by Lee Kai Chen in 1950 and is a combination of Suanpan and Soroban. It is known for its error-proof manipulation and versatility. 

Soroban- An unraveled abacus

Abacus is being used for centuries in China; it was brought to Japan in the 16th century. Some major changes were made to it as per Japanese taste. Accordingly, Sorobon has 1 top bead and 4 bottom beads— one less than the Chinese abacus, thus making calculations smoother and easier. Soon, various Japanese merchants began to use them. Mathematicians like Seki Kiwa do extensive studies on it to make improvements. The use of these reckoners is evident in Japanese schools today, retaining their value. 

The Japanese teaching style is distinct as instructors rely on organic estimators to strengthen the comprehension of Arithmetic, thus encouraging the employment of Sorobon to ameliorate calculating skills. 

Looking into the layout of the Sorobon, the upper bead has a value of 5 (Go-Dama), and each of the lower beads has a value of one. A dot is marked on every third row indicating a whole number completed; These may vary in size from 13 to 31rods. 

Abacus and Soroban: Marking off pivotal differences

Abacus is any estimator characterized by beads and rods which is operated by fingers. Soroban is a Japanese subclass of Abacus fabricated to entertain facile operations.
Each version of the Abacus has a divergent arrangement of beads and rods.Soroban embodies 1 bead in the top deck and 4 beads in the lower deck. 
Each model has distinct complexities in its operation.Soroban is apparently the easiest category of Abacus.
Have a history of more than two millennialsIt started appearing in the early 16th century
Most of the categories are rarely used today due to the advent of modern calculators.Sorobon is evident even today as a counting device in schools to ameliorate counting abilities in kids. 

Factors inclining towards soroban

The abacus has various benefits like enhanced concentration, personality development, faster calculations, and improved motor skills. Despite these gains and popularity in Japan conventionally, Soroban has a set of utilities that can make it a pre-eminent choice for you.

  • The best option for toddlers: Routinely, the best time to preach abacus is believed to be at the age of 4-6. Thus, incepting a simpler version (Soroban) can be supportive. The reduced bead numbers make calculations effortless. Evidently, Sorobans are splendid at solving all arithmetic calculations like addition, multiplication, division and subtraction. 
  • Easy to carry: Unlike the Chinese abacus which is made of a thick frame, Sorobans are handy and easy to carry to schools. Conventionally, they weigh about 120-200 grams.
  • Integration with calculator: Calculators with a built-in soroban abacus are available. These can make self-evaluation facile. However, these may need more investment.
  • Diversity of sizes: A learner can opt for one among various sizes available. While the range varies from 13 to 31 rods, the 17 rods model is most commonly used.
  • Based on the ten-number system: Parents often get bewildered to boost kids opting abacus in fear of clashes between the notion and math. Soroban can be their choice as it is based on a modern ten-number based system. The kid can make estimations comfortably using 0 to 9 on it. 

Soroban or Abacus- How to adopt one?

While there are multiple options of abacus available, it can be taxing to decide which one to choose from. Anyone among them can be taken in as the essence behind them is ultimately the one and the same. However, you can explore the following factors to boost up your decision process:

  • Demography: The region you belong to may affect your decision of choosing. Chinese, Korean and Taiwan may prefer employing Suanpan, while Japanese and a few other countries may prefer Soroban.
  • Dimensions and Variants: The ideal size preferred by instructors is that having a length of 10 inches. You may, however, choose as you desire from those ranging from poketables to slate size. Further, the number of rods can also be chosen from. A kid can start from a basic 13 -rod model.
  • Intricacy: Traditional abacus has 2 beads on topdeck, thus it may be arduous to learn, but it may facilitate complex calculations once mastered. The case with Soroban may be contrary here. Thus, the abacus may suit adults, while kids may prefer Soroban. 

Summing up

Comprehending the significance of the Abacus, many schools started to enact these reckoners in academics. Their level of acceptance can be sensed from the online classes offered. The choice between Abacus and a Soroban is often debatable. All the details assembled above may let us go around picking up Soroban. Apart from being a most used model, various other factors can bring us to these inferences. However, the choice is ultimately in the hands of the aspirants.
