Children bead counting is how to calculate?

Recently CCTV broadcast "Challenge Impossible" in Wu Meiling bead heart calculation, let a person is dumbfounded, feel so magical. Later I also checked some information on bead counting. As this is a newly opened field, there is no whole set of authoritative theories that have been confirmed by practice. Nevertheless, the teaching activities of bead counting have been confirmed by the current scientific and medical theories that there is a basis for positive effects, that is, the potential function of the human brain "brain image" does exist, "brain image" development is directly conducive to the human right brain activity. With these two scientific basis, we can be in the existing theory (even if incomplete) guidance and reference, from a practical point of view, pay attention to the research of the bead counting teaching activities, and constantly practice, constantly summarize, so that the rich teaching practice and experience for brain science, educational psychology to provide a large number of rich information, so as to enrich and improve the results of the research, in order to be more in-depth, more comprehensive theory to guide the bead counting teaching activities. Healthy development. Facts caution us: in the development of bead counting teaching activities, we must develop the psychological mechanism of bead counting, brain function. The following is a more complete recommendation of the bead calculation mnemonic.

In fact, this bead mental arithmetic, many people are surprised that it is magical, but also give it with a mysterious veil, that as long as my child learns this can become magical, computing superpower, in fact, do not understand what is called "bead mental arithmetic", in fact, its full name is "bead mental arithmetic", it is bead mental arithmetic. "It is the "brain image" in the brain after the skillful calculation of beads, which is a skillful combination of the traditional Chinese bead calculation method and image memory, and the results are obtained through the "brain image" (in the brain to plan the disk), and the calculation speed is so fast that it can be compared with the modern computer. The speed of calculation is so fast that it is comparable to modern computers!

Many parents blindly go to learn the bead counting, that learning the brain is very smart, math learning without a problem, in fact, not so much, including children even if the study of three or four grades with the finger counting, the bead counting is not to back this "black pot", it is in fact, and the children learn art, dance, that is, just a hobby, did not say that learning the art, dance, and so on. It is just a hobby, not to say that learning is an artist, dancer, bead counting people, that is, the top of the level! Not every child can reach that level, but both hands dial beads, the left hand movement opportunities greatly increased, conducive to the right brain development, effectively promote the left and right brain function of the comprehensive and balanced development, there must be a subtle effect, not instantly visible effect!

Learning bead counting, but also need to study hard, gradually by bead counting to bead counting, and "so-and-so family" growth is a reason, so it can not carry too much does not belong to its "denigration"! As a treasure of the traditional culture of the Chinese nation, bead counting has a long history, long life, once known as China's "fifth invention", must be inherited!

We should not waste food for fear of choking, please treat the national treasure!

Bead counting, hand-brain counting, do not learn. My family kindergarten learned, and now that regret ah, all three grades within the 20 addition and subtraction still have to break the finger counting. The first thing you need to do is to get your hands dirty!

The main purpose of the children's bead calculator is to memorize the image of the abacus in the brain, and then let the children use the abacus to calculate in the brain!

The purpose of children's mental arithmetic is not to teach children to intend the abacus, but for mental arithmetic! Mental arithmetic is all about planning an abacus in the brain!

Don't find it hard!

With the right approach, a five-year-old can master simple introductory mental arithmetic in a month! For example, 6-5+3+5-2-1= 6! This is a straight addition and subtraction mental math problem! After the introduction to mental arithmetic, such a problem with a normal speed of speech read, the child's answer is also calculated!

I've been teaching mental arithmetic for 12 years! I've been teaching beads for 12 years now, and those who can't do it are basically too old! Adults have no way or it is very difficult (very, very difficult) to learn mental arithmetic! But a 4 - 8 year old child will have no problem!

A child gets the most help when he masters mental math! Not only is he able to calculate quickly, but his reflexes are quicker and his attention span is better than that of a child of his age!

And it helps the child to train their spatial imagination! This is even more important!

Share my experience, the child was small, I let the child to learn a lot, painting, bead counting, English, martial arts, I think the child has to have a skill, but also listened to the chicken soup, so learn a lot, and now on the elementary school, I think the most unnecessary is the bead counting, of course, you think your child is a genius, except. For most children it is necessary to be down to earth to 10 and 20 within the oral math proficiency, for the bead counting is the training institutions of the chicken soup

My big baby is learning, just learned a semester. My intention is to help the early childhood, and at present every day to practice, this is mainly patient, insist on practicing the effect, and at the same time help to improve the child's ability to concentrate, my family in a good mood, concentrate on the time to practice the effect of a good.

The teacher first taught the beads, and then the mental math, straight plus and straight minus and with the mnemonic. The main thing is to be skilled, the brain will have a pictorial recognition of the abacus, dial beads in the brain.

The bead calculator is a calculation method that simulates the image of the abacus in the brain, transforms the numbers seen or heard into the image of the beads in the brain, and carries out the mental calculation in accordance with the principles of the bead calculator. Thus, in the brain, addition, subtraction, multiplication and division calculations.

Bead counting is not an ordinary oral math, not to mention math class, it is a course to cultivate comprehensive ability. It is not only able to forge children's ability to calculate and improve math performance, it can also improve children's attention, memory and logical thinking ability.

The calculation method of bead calculations is: First, let the child know the abacus, and then use the right and left hands to dial bead training, while guiding the child to the image of the abacus printed in the brain; Second, from the simple direct addition and subtraction of straight to begin with, the first dial on the abacus, and slowly try to dial the abacus in the brain, which requires a process, in fact, the conversion of the bead calculations to the calculation of the heart is the child's attention to focus on the conversion of one. Be sure to strengthen the training, at first the child may be a little uncomfortable, there is a lesson, will be able to adapt. Once you read the numbers, the child will be able to say the answer, indicating that the child's attention, the ability to calculate are improved. This greatly improves the speed of calculation; Third, from shallow to deep, solid learning the calculation of bead calculations. Each knowledge point of the bead calculation has a corresponding mnemonic, so that the child fully understands, and will memorize and utilize. Then, continue to practice over and over again. First practice with an abacus, and slowly try to calculate mentally. Only by practicing more will you get good results.

In short, the study of bead calculations and learning other courses, as well, to have patience, to learn and practice hard, can not be based on the enthusiasm of the moment want to learn to learn, do not want to learn to give up.

First of all, the bead calculator, we all know that the abacus as a tool for computing a calculation method, known as the fifth great invention of ancient China.

The bead calculator is the abacus disk type, grade and bead floating changes depicted in the brain, the image of the living abacus, known as the "virtual disk". This through perception, image, memory and other processes, in the brain to complete the bead calculation, this is the bead calculation method.

The author's children have studied bead calculations in the pre-school stage, bead calculations in the calculation, the child concentrated, and even close their eyes, in the mind of the virtual abacus and arithmetic process, so children learn bead calculations, for improving concentration, the development of intelligence is very helpful.

The brain is used to complete the abacus disk style, grade and the floating change of the abacus beads to complete the calculation.

In the process of teaching bead counting, bead counting is the foundation. Through the operation of the real beads (abacus), learners can understand the changes and methods of the four rules of calculation. With the skillfulness of the technique, the image in the learner's mind is gradually built up, and through the simulation of the image (the virtual disk), the function of mental calculation is generated, so the mental calculation is the advanced manifestation of the bead calculation. The two are just like two feet, and you can't choose one to walk alone.

The study of bead calculations can be skillfully mastered to the ability to calculate and the ability to memorize. And memory ability in the appearance, is the process of mental arithmetic is the most important bead image, the calculation process, the bead image, from the static bead instantly and continuously into a lot of moving beads running, in a very short period of time to complete. So the more skillful the bead counting skills, the more the degree of mental arithmetic is played.

Therefore, in the process of learning bead calculations, bead calculations and mental calculations should go hand in hand, bead calculations in the first to lay the foundation, and mental calculations in the latter instantly indicated. Bead counting in the difficulty of the gradual increase, will be slow progress, but the heart counting can be more fluent and unimpeded, the sky is the limit.

Algorithmic mnemonics:

The mnemonics are unique to bead calculations, and were first described in Wu Jing's "Nine Chapters of Algorithmic Comparison and Classification" (1450). The "nine-nine" mnemonic used in multiplication has a very early origin, and was already used in calculations during the Spring and Autumn Period and the Warring States Period. The Northern Song Dynasty scientist Shen Kuo said in his "Dream Stream Brush Tales" Volume 18, when introducing the "Increase into the method": "Only the increase into a slightly different method, the art of multiplication and division, but make up for the loss on the surplus only.

If you want to add one to nine divisors, you can do so, and if you want to add two to eight divisors, you can do so, but you have to add one to one. The phrase "if you want to divide by nine, add one" was later changed to "if you want to divide by nine, add one", and "if you want to divide by eight, add two" was later changed to "if you want to divide by eight, add two", and so on. The "add one to divide by nine" was later changed to "add one to divide by nine".

In the middle of the 14th century, Ding Ju compiled eight volumes of algorithms (1355), which contained the recipe of "bumping and dividing". In short, all the recipes for division and categorization were completed in the Yuan Dynasty. With the four mnemonics, the algorithm of bead counting formed a system and was used for a long time.

The Chinese abacus, since the Ming Dynasty, has been extremely popular, and has been spread to Japan, Korea, Southeast Asia, and then in the Americas. Because the abacus is not only a very simple calculation tool, but also has a unique educational function, so it is still prevalent.

There are related training institutions, you can go to the consultation to understand. The child has to be interested in order to learn well.
