The abacus is used to teach children arithmetic. An abacus tool allows children to perform basic operations like addition, subtraction, multiplication, and division. As children progress in learning the abacus, they can learn long division and using the operations with negative numbers.
Besides enhancing the overall comprehension of mathematics, the abacus offers other important benefits.
What is an Abacus?
An abacus, also known as a counting frame, is a calculating tool with beads that slide across on wires or rods. The most common abacus is split into two rows:
The top row (upper beads) is for the “fives”
The bottom row (lower beads) is for the “ones”
The upper beads are located in the upper deck and the lower beads are located in the lower deck.
Besides the rows, the abacus has different columns. Each column represents a place value such as tens, hundreds, and so on. The amount of place values varies depending on the size and design of the 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. 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.
Around the world, abacuses have been used in pre-schools and elementary schools as an aid in teaching the numeral system and arithmetic because:
