Drum Japanese abacus. Japanese soroban abacus

Every parent dreams of their child growing up as an intellectually developed and intelligent person. But for this to happen, good genetic data will not be enough. Any abilities need to be developed and improved, and the sooner you start doing this, the sooner the baby will delight you with his successes.

Abacus abacus has long been used in specialized schools and kindergartens for mental arithmetic. If you want your child, in the future, to count faster than a computer, then you definitely need to buy an abacus-soroban abacus.

abacus abacus

Instant arithmetic has a huge number of advantages. Is it possible, standing at the checkout in a supermarket, to know the amount of your purchase even before the cashier announces it, passing the goods through the tape? Yes, if you are trained in the soroban method. Such a person is almost impossible to deceive. Learning to count using this technique will be useful not only for children, but also for adults.

But most often, soroban buy abacus precisely in order to teach the child addition and multiplication in an interesting game form. This game will serve and turn counting into a fast and interesting process.

Back in the 16th century, our ancestors successfully used Japanese abacus, and our great-grandmothers used them for bookkeeping before the advent of calculators. And although today there are many gadgets for quickly solving any example, do not forget that they all just give the correct answer, without training the brain.

It has been scientifically proven that our brain works much more intensively if it is accompanied by some kind of action. That is why, by moving the counting rings, the child will think much faster. As for calculators, these same scientists have proven that an electronic calculator is a great way to relax the brain, ruining even the most minimal mathematical knowledge.

Japanese soroban abacus

The most suitable age for mastering soroban mental arithmetic is considered to be from 4 to 12 years old. It is during this period of life that the active development of the brain takes place. Therefore, instilling the necessary skills in a child should begin at a preschool age. In our online store, you will be offered two types of soroban abacus.

The first, with colored plastic beads, located on 13 bamboo bases. This color scheme will delight the smallest mathematicians. The bright colors of the beads will help to attract the attention of the baby.

The latter are made in a calmer color scheme. Plastic beads are painted "under the tree". Also in this version there are 4 black separating beads, which will allow the child to quickly navigate in tens and hundreds. These soroban abacuses are worth buying for children who are already more consciously engaged in arithmetic.

By teaching your child how to play soroban, you will be able to learn and improve your knowledge with him. Soroban is a toy suitable for all ages. The more often you practice the soroban counting technique, the more perfect your knowledge of mathematics will be. The peak of perfection is the ability to count soroban on Japanese abacus with both hands, activating both hemispheres of the brain at once.

Of course, without the help of adults, the child himself will not be able to comprehend this art. But it's a great opportunity to spend time together.

Abacus soroban

Japanese abacus is located in a plastic frame. The dividing strip separates 1 knuckle from 4 on all 13 needles. In order to dial the number 3 on the Japanese abacus accounts, you need to separate the three beads located behind the dividing strip. To set the number 13, you need to set aside 3 beads on the upper knitting needle and one on the penultimate knitting needle.

And now let's try to add 13 to 3. To do this, to the number 13 already set aside, add 3 beads on the upper knitting needle, set aside 1 bead in front of the dividing strip and one after it, it turns out 6 and 1 dozen remains the same, 16. Having bought Japanese soroban abacus, your child will learn to count very quickly. Abacus is a great way to consolidate the material covered at school.

When a child learns to imagine the soroban abacus in his imagination, he can easily count in his mind any examples of addition, subtraction and multiplication.

Advantages

• Attractive appearance;
• Develop mental abilities and train the brain;
• Improves visual memory;
• Help the child to concentrate on the tasks;
• Make the learning process interesting;
• Develops fine motor skills of hands.

What is soroban, not everyone knows. Indeed, in the world of electronic technology, it is much easier to press the calculator button without straining the brain. But is it worth simplifying tasks and raising a generation capable of doing calculations only with the help of computers?

Buy an abacus and in a few years you will be proud of your child's knowledge of mathematics. Buying an abacus-soroban abacus in an online store, you not only get a beautiful toy, but also make a significant contribution to the development of your child. Such a toy will be a good and useful gift. Soroban Finger Counting Game is a great way to prepare your child for school.

Nations that use hieroglyphs have a different way of thinking. Does it affect their lives? It is hard to say. Such people are visual by nature, they figuratively perceive the world around them. And this system of perception does not bypass even the exact sciences. How the Japanese multiply will be interesting for everyone to know. Firstly, you don’t have to panic looking for a calculator, and secondly, this is a very exciting activity.

We draw

It's amazing, but Japanese children can multiply without even knowing about the multiplication table. How do the Japanese multiply? They do it very simply, so simply that they use only basic drawing and counting skills. It is easier to show with an example how this happens.

Let's say you need to multiply 123 by 321. First you need to draw one, two and three parallel lines, which will be placed diagonally from the upper left corner to the lower right. On the created groups of parallels, draw three, two and one lines, respectively. They will also be placed diagonally from bottom left to top right.

As a result, we get the so-called rhombus (as in the figure above). If someone has not yet understood, the number of lines in the group depends on the numbers that need to be multiplied.

We believe

So how do the Japanese multiply numbers? The next step is to count the intersection points. First, we separate the intersection of three lines with one in a semicircle and count the number of points. The resulting number is written under the diamond. Further, in exactly the same way, we separate the sections where two lines intersect with three and one. We also count the points of contact and write them down, then we count the points that remained in the center. You should get the same result as in the picture below.

It is worth paying attention to the fact that if the central number is two-digit, then the first digit must be added to the number that turned out when counting the points of contact in the area to the left of the center. Thus multiplying 123 by 321, we get 39,483.

This method can be used to multiply both two-digit and three-digit numbers. One problem is that if you have to count numbers like 999, 888, 777, etc., then you will need to draw a lot of dashes.

The counting technique called Soroban is now spreading at the speed of light. Its goal is to develop the mental abilities of children, evenly involving the left and right hemispheres. This technique is more than 25 years old in Japan, it has been working in post-Soviet countries for 3 years. But the most interesting thing is that the accounts on the basis of which it is built are already more than 2.5 thousand years old. And only now, from the distant countries of Asia, this counting tool is beginning to spread around the world.

What is an abacus?

Abacus (Abacus), or Soroban, is an ancient abacus that was used in the ancient countries of Asia and Europe. In China, they were called abacus (in Latin "abacus"), in Japan - Soroban. However, they were also used in ancient Rome and Greece. The abacus changed somewhat depending on the country where they were used, but the essence remained the same.

The abacus is a frame divided by a crossbar. In the upper part there is one line of bones. Each bone in it means "five". Below are rows of bones, each of which has 4 bones. Each of them means "one".

The bones on the Soroban or Abacus abacus are specially pointed so that children, sorting through them, develop fine motor skills. The abacus stands for units, tens, hundreds, thousands and millions. With the help of Soroban, children quickly master mental counting and can even multiply multi-digit numbers.

How are the classes going?

The Soroban abacus training methodology, or Mental Arithmetic, allows you to develop children's abilities to unprecedented heights. The main instrument for this is the Abacus abacus. At the first stage, children learn how to use abacus.

In the second step, children visualize the Soroban abacus in their minds. Those. the child begins to imagine Soroban in front of him and make calculations in his mind. In this case, 3 mathematical operations are mastered:

• addition;
• subtraction;
• multiplication;

The training lasts 2 years. The best time to start learning is between the ages of 5 and 11. This age is considered optimal. But this does not mean that the Soroban technique is not available for older children and adults, it just may take more time to learn.

Classes in Soroban centers are held for 2 hours once a week. Children are given homework assignments. If they are completed, the trainer opens access to the following. A quarter of an hour a day is enough to complete the task. The program can be adjusted individually depending on how each child is doing.

How to use?

To learn how to use accounts, you need to know what they are. Accounts consist of:

• framework;
• dividing line;
• upper bones;
• lower bones.

There is a center point in the middle. The top bones represent fives, and the bottom bones represent ones. Each vertical strip of bones, starting from right to left, denotes one of the digits of the numbers:

• units;
• tens;
• hundreds;
• thousands;
• tens of thousands, etc.

To postpone the number, it is necessary to move the bones to the dividing line on the accounts, according to the numerical designation corresponding to the number of each category. For example, to postpone the number 165, you need to move the top bone on the right on the first line (it means five), on the second line - the top and one bottom bone (5 + 1 = 6), on the third line - one bottom. So we get the required number.

Further calculations will be accompanied by the movement of the bones along the lines according to the ranks.

What does mental arithmetic give?

Japanese abacus called Soroban teaches not only to count, although children achieve unprecedented success in this. Toddlers can easily calculate 10-digit numbers in their minds, multiply and subtract. But a quick mental count is not the main goal.

• the ability to concentrate;
• activation of auditory and visual memory;
• improving intuition and ingenuity;
• ability to solve problems in a non-standard way;
• the manifestation of independence and self-confidence;
• realization of abilities and a successful career in the future.

The technique is based on the power of imagination. It is thanks to her that it is possible to speed up thinking, to establish accelerated connections between the right and left hemispheres of the brain. Children who studied according to the Soroban method learn foreign languages ​​faster, study well at school, and are more purposeful.

Many parents probably dream that their baby will grow up special and will certainly become such that he can be proud of. But if some fathers and mothers only brag about the abilities of their children, then others take them to special schools that help develop the inclinations given by nature.

Is it possible to grow a genius out of a child? If in the old days the answer to such a question was unequivocal and required the presence of talent and amazing abilities, today the task has become much simpler. For example, in order for a child to show remarkable knowledge in mathematics and count as quickly and correctly as a calculator, an unusual program is offered that will teach a child mathematics. And it is called "mental arithmetic". What is this program and what are its benefits?

The popularity of the technique

Since 1993, mental arithmetic has been used to teach children in 52 countries around the world, from Canada to the UK. In some of them, the methodology is recommended for inclusion in the curriculum of schools.

The mental account has received the greatest distribution in the states of the Middle East, and also in China, Australia, Thailand, Austria, the USA and Canada. Specialized organizations are beginning to appear in Kazakhstan, Kyrgyzstan and Russia.

Mental counting is one of the youngest and fastest growing methods used for children's education. Thanks to this technique, you can easily develop the child's mental abilities, which primarily have a mathematical orientation. Thanks to the development of mental counting techniques by children, any mathematical problem turns for them into a simple and fast computational process.

History of occurrence

The method of mental counting has ancient roots. And this is despite the fact that it was developed relatively recently by a scientist from Turkey, Halit Shen. What did he use for his mental counting system? Abacus, which was created in China 5 thousand years ago. This item is an account that has made a huge contribution to the development of the entire world of arithmetic. After the invention, the abacus began its gradual spread throughout the world. In the 16th century, it came from China to Japan. For four hundred years, the inhabitants of the Land of the Rising Sun not only successfully used such accounts, but also carefully worked them out, trying to improve such an object necessary for performing arithmetic operations. And they succeeded. The Japanese created the soroban abacus, which is still used today to teach children in elementary school.

Throughout the history of human development, mathematical science has been improved. And today it can offer us a huge number of its achievements. But despite this, scientists believe that the use of an abacus is more beneficial in teaching children to count accurately.

Benefits of mental arithmetic

It is believed that each of the hemispheres of the human brain is responsible for its own directions. So, the right one allows you to develop creativity, figurative perception and thinking. The left is responsible for logical thinking.

The activity of the hemispheres is activated at the moment when a person begins to work with his hands. If the right one is active, then the left hemisphere starts to work. And vice versa. A person working with his left hand contributes to the activation of the work of the right hemisphere.

The task of the menar is to force the whole brain to take part in the educational process. How to achieve such results? This is possible when performing mathematical operations on the abacus with both hands. Ultimately, the menar contributes to the development of fast counting, as well as the development and improvement of analytical skills.

Scientists compared the calculator with an abacus and came to the unequivocal conclusion that the first of them relaxes brain activity. Abacus, on the contrary, hones and trains the hemispheres.

When should you start learning mental counting? Reviews of adherents of this technique claim that it is best to master this method at the age of four to twelve. And only in some cases, the period can be extended for another four years. This is the time when the brain develops rapidly. And this fact is a wonderful message to instill in the child basic skills, study foreign languages, develop thinking, master playing musical instruments and martial arts.

The essence of the mental technique

The entire program for the development of oral counting is built on the successive passage of two stages. At the first of them, acquaintance and mastery of the technique of performing arithmetic operations using bones takes place, during which two hands are involved simultaneously. Due to this, both the left and right hemispheres are involved in the process. This allows you to achieve the fastest assimilation and performance of arithmetic operations. In his work, the child uses an abacus. This item allows him to absolutely freely subtract and multiply, add and divide, calculate the square and cube roots.

During the passage of the second stage, students are taught mental counting, which is performed in the mind. The child ceases to be constantly attached to the abacus, which also stimulates his imagination. The left hemispheres of children perceive numbers, and the right hemispheres perceive the image of knuckles. This is the basis of the method of mental counting. The brain begins to work with an imaginary abacus, while perceiving numbers in the form of pictures. The performance of the mathematical calculation is associated with the movement of the bones.

Learning mental arithmetic for quick counting is a very interesting and exciting process. He is appreciated by hundreds of thousands of people and received a huge amount of positive feedback.

abacus

What is this mysterious and ancient calculating machine? Abacus, or abacus for mental counting, is very reminiscent of the old Soviet "knuckles". The principle of operation on these two devices is very similar. What is the difference between these accounts? It lies in the number of knuckles on the needles and in ease of use.

It is worth saying that in order to get the result, the abacus will require more hand movements. How does this ancient object, which came to us from China, work? It is a frame in which the needles are inserted. Moreover, their number may be different. On the needles there are five pieces of strung knuckles.

In length, each spoke is crossed by a dividing bar. Above it is one knuckle, and below it, respectively, four.

The mental counting technique provides for a certain movement of a person with fingers. Of these, only the index and large are involved. All movements should be brought to automatism, which is facilitated by their repeated repetition.

Interestingly, this skill can easily be lost. That is why, when mastering the technique, you should not skip classes.

Arrangement of numbers

What are the basics of counting in mental arithmetic? In order to master this technique, you need to know how the number rulers are located on the abacus. On its right side are units. After that come tens, then hundreds, after a thousand, tens of thousands, and so on. Each of these discharges is located on a separate spoke.

The knuckles located under the dividing bar are "1", and above it - "5". For example, in order to dial the number 3 on an abacus, you will need to separate three bones located under the dividing bar on the knitting needle located to the right of the others. Consider an example with double numbers, for example, with 15. To set it on an abacus, you should raise one knuckle on the tens needle and lower one located above the top bar on the units needle.

Addition operations

How to learn mental counting? To do this, you will need to study how arithmetic operations are carried out on the abacus. Consider, for example, addition. Let's see what the sum of the numbers 22 and 13 will be. First, you need to set aside two knuckles on the needles of tens and ones, located at the bottom of the dividing bar. Next, to two tens, add another one. It turns out 30. Now let's start adding units. Let's add three more to two. You get the number "five", which is indicated by a knuckle at the top of the dividing bar. The result is 35. To master more complex operations, you will need to carefully study the special literature. After mastering the simplest examples, it is recommended to practice on the abacus. Thus, learning becomes as interesting as possible.

Mastering the second stage

After the operations on the abacus will not cause difficulties, you can proceed to the mental calculation of mental arithmetic. This is the next level of learning. It involves a mental account, that is, produced in the mind. To do this, you need to make a picture of an abacus for the child. The simplest option is to print out an image of this item, which should then be pasted onto cardboard (you can take it from a shoe box). If possible, the picture should be in color. This will make it easier for the child to imagine it in their imagination.

To avoid mistakes, it is worth remembering that mental counting should be done from left to right. What needs to be done to put a two-digit number on the abacus? To do this, the child should first pick up the knuckles corresponding to tens with his left hand, and after the right hand, separate the necessary units on the knitting needle.

So, for dialing 6, 7, 8 and 9, you should use "Pinch". This process is bringing together the index finger and thumb to the dividing bar and collecting the bones that represent the number 5 and the required number of them on the needle, which is located at the bottom of the abacus. Subtracting numbers is done in a similar way. The same “Pinch” simultaneously discards the “fives” and the required number of bones below.

Objectives and results of the methodology

Teaching mental counting allows the child to achieve unprecedented success in the field of mathematics. Children who have completed a special course can easily calculate ten-digit numbers in their minds, multiply them and subtract them. But it is worth saying that this is not the main goal of such training. Counting is only a means by which a person's mental faculties develop.

Mastering mental arithmetic contributes to the following:

• activation of visual and auditory memory;
• the ability to concentrate;
• improving ingenuity and intuition;
• creative thinking;
• showing self-confidence and independence;
• rapid development of foreign languages;
• realization of abilities in the future.

In those cases when a professional approach was used to master the menar and the specialists achieved their goals, the child easily begins to solve both simple and complex mathematical problems in his mind. And it performs arithmetic operations for multiplication and addition even faster than a calculator.

Schools for teaching mental arithmetic

Where can you learn this unique technique? Today, to study mental arithmetic, you need to enroll in a specialized educational center. In them, specialists have been working with children for two to three years. In addition to the steps described above, with the help of which you can master the technique, there are ten more steps. Moreover, students pass each of them in 2-3 months.

Each of these specialized centers develops its own training programs. However, despite this, there are general rules that absolutely everyone adheres to. They consist in the fact that groups of students are formed depending on their age. So, there are three basic types of such groups.

These are kinder, kids and junior. Classes are conducted by experienced highly qualified psychologists and teachers who have undergone appropriate training and have the necessary certification.

In addition to mental arithmetic training centers, there are also specialized schools that train specialists in the relevant field. As a rule, menar teachers are people who have not only a psychological and pedagogical education, but also some experience in working with children. And this is very important. After all, learning to mental account is not only the development of skills that allow you to work with ancient accounts. In this process, the psychological characteristics used in pedagogical practice in the development of the child are certainly taken into account.

If your child cannot master solving mathematical problems and memorize the necessary formulas, and preparing homework turns into a nightmare, the Japanese Soroban counting technique can be a lifesaver. This method surprisingly helps to develop children's thinking.

The unique method of mental counting allows even those guys who do not have the ability to do arithmetic at all, after a short period of time, learn how to easily solve problems, enjoying the process.

Features of the mental account

The Japanese method of quick counting is a unique system for the development of babies and the transformation of children's thinking. This method allows you to use both hemispheres of the brain at the same time, which provides even bright humanitarians with the opportunity to quickly learn how to solve various examples.

Learning to count according to the Japanese method is based on the use of special accounts called soroban - this non-traditional device is not often found in our country. This is a kind of calculator that demonstrates only an unambiguous system of numerical representation, which guarantees the clarity and comprehensibility of the system.

The soroban always uses an odd number of needles arranged vertically, with each of them assigned the designation of one number. Any spoke has five bones, where the four lower ones are reserved for units, and the upper one is for “five”.

The child is fascinated by this Japanese method of oral counting and the abacus itself, which allows you to quickly master the process, and the main advantage of the method is the incredibly rapid development of thinking.

Basic principles of the method

The Japanese method mental arithmetic system is designed not only to teach students mental arithmetic, but also to develop their intellectual skills in general. It is a known fact that the hemispheres of the human brain work unevenly, and a child of 5-8 years old mainly uses the right side, which is responsible for creativity and emotional images.

When learning to count occurs, the load on the left side increases, rationality and logic develop, which systematically reduces creativity. The Japanese method of counting in the mind allows you to balance the work of the brain, ensuring full development.

With the help of abacus work, children develop intellectually, begin to think faster and easily achieve success in any learning. Similar results are provided by the main principles of the Soroban methodology:

• Manual motor skills through training. The brain controls human actions, but there is also a reverse process, so working with special accounts with the fingers of both hands improves children's thinking.
• Systematic work. None of us are born the best, and in order to achieve the top in any field, you need to train regularly. The Japanese method of counting also works according to this principle.
• Visualization. Possessing visual materials expressed in soroban counting bones, it is much easier for a child to understand numbers and understand the meaning of calculations.

What is needed to learn mental arithmetic?

Soroban will assist in teaching a child to count only if the training was started in a timely manner, at the age of about 4-8 years. Parents should be patient and move gradually, because this procedure needs a certain amount of time. Also important conditions for success will be:

• Teaching a child according to the method "from the simplest to the complex". At the first stage, you need to master the count to ten, after which the reverse count.
• The kid needs to be taught to count from the age of two, but learning to numbers and figures can be started at about four years old, when the baby is able to consciously count the objects in his field of vision.
• Exercises should be carried out in a relaxed atmosphere, but not in the form of lectures. Children learn best through play, which connects emotional perception and increases the effectiveness of learning.
• The difficulty of tasks should be gradually increased. Also teach your baby the differences between the signs "greater than", "less than", "equal to".

With this initial training, you can freely send your child to the soroban Japanese mental arithmetic school, where professional teachers will study the child’s personal characteristics, take into account his abilities and skills.

To master the Soroban method, you can contact the online Japanese language school of Daria Moinich. You can find out more information at.

Advantages of mental arithmetic from Japan

Children develop their skills in using soroban quite quickly, which has an incredibly beneficial effect on the development of thinking. Toddlers learning to count on a soroban can do heavy mental calculations in the blink of an eye, while true professionals of the technique are able to perform them even without a soroban. Just a couple of seconds will be enough to add 3-digit numbers, and then, when the skills are perfected, the child will be able to operate with 5-digit numbers.

This technique guarantees the child success not only in arithmetic, but also in other areas of knowledge acquisition. According to teachers and psychologists, Japanese abacus increases children's focus and concentration, improves memory, resourcefulness and imagination, as well as improves creative skills. Children begin to grasp information on the fly and quickly analyze it.

Some parents believe that their child may get confused when combining traditional and Japanese arithmetic, which will lead to a drop in school performance. However, practical experience shows that after a few months, a child practicing soroban begins to show talent in the exact sciences and is ahead of his peers in development.

All the mentioned advantages of mental counting are only the basis of a key advantage - mental arithmetic allows you to open and nourish the child's intellect, as well as educate a personality, instilling confidence, independence, and the ability to achieve success in any situation.
