Abacus Soroban calculator came to us from Eastern countries. Modern Japanese still consider them the best exercise for children's minds. Traditional counting on paper engages only the left hemisphere of the brain, which is responsible for logical thinking, while the abacus promotes the work of both hemispheres. As a result, the child learns to look at one problem from different angles, finding several options for solving it.

The wisdom of the East
Mental arithmetic, that is, performing operations with numbers in the mind, is widespread throughout the world, and in Japan it is even included in the compulsory school curriculum. This method of counting trains the brain, increasing the number of neural connections. It is important to understand that this is not mathematics in its classical sense. You don't need to know theorems or formulas at all - before you is a simulator that teaches from a different approach to computational operations.

Outwardly, the soroban is an elongated frame into which rows of knitting needles are inserted. 5 beads are strung on each of them. There is a dividing bar in the upper part of the item, it crosses all the spokes and separates the upper bead on each of them.

How to use an abacus soroban calculator

Counting is done from right to left. The first row is units, the second is tens, the third is hundreds, the fourth is thousands, and so on. Before starting the class, reset the soroban: the lower bones should be moved down, and the upper ones - up.

To count, for example, 3 units, lift the required number of beads to the dividing bar. If you need the number 6, then lower the upper bone to the bar - it means "5" - and raise 1 lower one. Tens, hundreds and all subsequent rows are counted in exactly the same way.

Adding and subtracting numbers is quite simple, move the dice and make the task more difficult for yourself. The peculiarity of the abacus is that you immediately see the result of a mathematical operation. Arithmetic turns from hard work into skillful management of numbers, and thinking in abstract images makes this process fast and correct, eliminating errors.

In the future, mechanical operations with the abacus are replaced by an imaginary representation of addition and subtraction on dice.

Benefit for development
Learning this technique should be started as early as possible, when brain cells are actively forming. The specific ability to count in the mind not only instills a love for mathematics, but also has a much greater impact on intelligence. Due to the synchronous work of both hemispheres of the brain, logical thinking is simultaneously trained and creative abilities are revealed.

In addition, with the help of soroban, your child:

calculates quickly without a calculator,
develops imagination
improves photographic memory,
notes that it is easier for her to learn texts by heart, and foreign languages are easier,
becomes attentive
increases the speed and accuracy of the reaction,
gains self-confidence.
Learn mental arithmetic!
