I m talking about junior high school students, is it useful to learn mental arithmetic to learn math

If you can do mental arithmetic.

If you really learn well, it will definitely be of great help to the child in the future, but this should be decided by the child himself, if the child does not want to learn, do not force it, because if the child is forced to learn by adults, it will definitely get worse and worse. Advice is good for deeds, and good medicine is good for disease.

Mental arithmetic is very helpful for children's math and can be learned if the child wants to. Learning well allows for quick calculations and at the same time boosts your child's self-confidence.

The so-called abacus mental arithmetic, that is, abacus-style mental arithmetic. Abacus is based on an abacus.

It is a calculation method for addition, subtraction, multiplication, division, square, etc. When the user can skillfully operate the abacus, in addition to quickly finding the correct answer, it can also penetrate the brain cells.

The growth of the abacus is depicted in the brain, the type of the abacus, the grade and the fluctuation changes of the abacus, that is, there seems to be a live abacus in the brain, and the image of this live abacus is called a virtual disk. It uses perception, image, memory and other processes to complete abacus in the brain, which is what we call abacus mental arithmetic.

Abacus-style mental arithmetic, its speed is very amazing. Often, as long as you hear the number of questions or see the type of calculation question yourself, the calculator can blurt out the answer or write it out immediately. So abacus mental arithmetic calculation technique.

Not very useful. Classes will give you an abacus.

It's all done with a pen, which is simple and fast. And for some questions with relatively large data, some special quantities will be set. It's okay if the computing power isn't terribly bad.

I have met many large class children who have taken the entrance test, and their arithmetic ability is very strong, and the result of the inquiry is that they have participated in mental arithmetic training. In the short term, the algorithm can improve children's computing speed and ability, but it is not developmental, and it does not intersect with the algorithm in primary school, does not match, and will be forgotten when it is not needed in primary school. In comparison, conventional mental arithmetic methods are more practical.

In addition, children who learn mental arithmetic vary greatly from person to person. Children of the same age learn together, some children accept quickly, progress quickly, parents will praise the method is good, but there are also children who learn slowly, even if a lot of practice, but the effect is not significant, students and parents are very suffering. Because the average child learns slowly, both parents and children will be frustrated, making parents feel that their children's intelligence is not good.

It is advisable to give your child a try and see how well your child feels and accepts.

Hope it helps.

Hello, I have seen your question, and the answer is being sorted out rapidly, please wait for two minutes

Hello, in my opinion, it is necessary to learn mental arithmetic for the following reasons:

1) Mental arithmetic is helpful for opening up the intellect.

The intellectual development of a person is closely related to the regular exercise of finger movements, and the movements of operating the abacus are faster, more detailed and subtle, which is more in line with this principle. Many educational research experts at home and abroad believe that abacus mental arithmetic is an advanced stage of abacus and is more conducive to the development of intelligence. Parents who have let their children learn mental arithmetic know that after learning mental arithmetic, their children's hands-on ability is significantly enhanced, and they are more sensitive to numbers, which is of great help to open up their children's intelligence.

2) Mental arithmetic helps improve children's attentionAlthough attention is an innate ability, not everyone is able to focus on one thing, especially children who are in the learning stage. Inattention is a common problem of many children, and how to solve the problem of children's inattention is a headache for many parents. Because mental arithmetic requires both hands and eyes, it is possible to make mistakes if you are not careful, so learning mental arithmetic can help improve children's concentration.

3) Mental arithmetic helps to stimulate children's enthusiasm for learning, mental arithmetic is different from oral arithmetic and mental arithmetic in mathematics, it is a combination of traditional abacus and its algorithm, which is more difficult than oral arithmetic and mental arithmetic in terms of learning difficulty. Since abacus requires the use of abacus and the recitation of abacus formulas, this is conducive to enhancing children's strong desire for knowledge and can stimulate children's enthusiasm for learning. It can be said that learning mental arithmetic is a subject of learning, and it is a choice that kills multiple birds with one stone.

In short, if conditions permit, if the child is also interested in mental arithmetic, it is completely possible to try to let the child learn mental arithmetic. Right.

It is not recommended to learn mental arithmetic.

In the modern computer information age, basic operations or more complex operations have been basically handed over to computers. So whether we still need to learn how to calculate, the answer is yes. So what calculations do we need to learn?

My suggestion is that those in the textbook can be learned thoroughly, and those recommended by some training courses in other societies are not recommended to learn, and sometimes learning is not coincidental but affects the learning of normal calculation methods!

It has a counterproductive effect and delays children's understanding and operation of logarithms, so do not learn!!

Please wait a moment and I will answer your questions thoroughly.

I'm glad to answer for you, and I wish you a happy life!

Mental arithmeticIt helps with children's math. Generally speaking, children who learn mental arithmetic will have a better understanding of the concept of mathematics and physics, and their computing ability will be much faster than that of ordinary children.

Features of mental arithmetic

Abacus. The number counting is simple and bright, it is to learn the number of beads, to file positioning, the hierarchy is clear, the addition is subtracted, the subtraction is added, the multiplication and division are inverse, the arithmetic algorithm is clear and clear, and the children are easy to learn and remember, in addition, the abacus mental arithmetic education middle ear.

Actions such as listening, seeing, reading in front of the mouth mask, manual, lightning-fast counting and counting beads are all in line with the development and movement of children's auditory vision, so they are easy to be accepted by children.

In line with the development of children's auditory vision and the law of orange movement, children are characterized by fun, curiosity, intuitive understanding of things, when learning mental arithmetic, abacus this specific, intuitive, image of the counting tool for beginner children, is not only a teaching aid, but also a learning tool, but also a toy, when they come into contact with the abacus, the beads are counted, the beads move are changed, as if doing a game, fun and attractive, can cultivate a strong interest in learning.

It is not good for children to learn mental arithmetic, and it may make children lose interest in calculations, which in turn will affect their learning and performance.

The 80s and 90s generation like me basically learned the plan when they were in elementary school, in fact, mental arithmetic is also a mental arithmetic method based on this brigade spine. What I was most afraid of at that time was to be calculated, such as: one up, two on two, three down five to two, four down five into one ......Make yourself feel like a headache.

Now the abacus does not need to use the abacus, that is, the child simulates the abacus in the mind to calculate, some children will close their eyes when doing the problem, the mouth vibrates with words, and the hand is as if they are planning to play with the plate, which will bring the following drawbacks:

Influence mathematical calculations

Yes, you read that right, although mental arithmetic learning can improve the speed of calculation, but after a long time, it is easy to affect children's mathematics learning and calculation accuracy. Because mental arithmetic is a tricky method, some children are reluctant to spend time checking the calculation as long as they make the answer when they learn it. If this continues, it is easy to lead to low-level errors.

When I tutored my nephew to do math calculations, I always asked him to calculate vertically step by step, and to check the calculations, so that he could understand the importance of the basic problems and ensure the accuracy of the problems without being opportunistic.

Not much practicality

Zhuxin Scattered Arithmetic is only a quick arithmetic skill, which has an auxiliary effect on calculation, but it cannot improve children's logical thinking ability, as well as the combination of numbers and types, so if you want to improve your math score by learning mental arithmetic, then it is basically ineffective.

When I tutored my nephew, I found that those who did poorly in mathematics (my nephew was) often did not have a good understanding of fill-in-the-blank questions and application questions, and could not read the meaning of the questions.

Loss of interest in learning

There are still some difficulties in the learning of mental arithmetic, and some children feel that it is difficult to master after learning, so they will be afraid of difficulties, feel that mathematics is too difficult, and even affect the learning of textbook content.

In summary, the disadvantages of mental arithmetic are still relatively obvious, but it is not that it is completely useless, in fact, for children with good math scores and spare time, learning mental arithmetic is still beneficial to them, but it is best for children to have their own willingness to learn, after all, interest is the best teacher.

Therefore, mental arithmetic is not a must for children to learn mathematics, parents should still be determined by situation when letting children learn, otherwise it is easy to burden children, waste time and money, and finally do not help learning, which outweighs the losses.

Learning mental arithmetic is useful.

The so-called abacus mental arithmetic, that is, abacus-style mental arithmetic. Abacus is a calculation method that uses the abacus as a tool to add, subtract, multiply, divide, and open squares. There are certain rules and formulas for its bead transport skills, and the user can operate it proficiently.

In addition to quickly finding the correct answer, it can also depict the disc type, grade and fluctuating changes of the abacus into the mind, and the image of this living abacus is called "virtual disk". It completes the abacus operation in the brain through the processes of perception, image, memory, etc., which is what we call abacus mental arithmetic.

Learn how to stop the land:

In the study of abacus, students can master their numeracy skills and memory skills. The appearance of memory ability is the most important abacus image in the process of mental arithmetic, and in the process of calculation, the abacus image and the balance limb are continuously transformed from static beads into many moving beads in an instant, which is completed in a very short time. Therefore, the more proficient the abacus skills, the more superb the mental arithmetic will be.

Therefore, in the process of learning mental arithmetic, abacus and mental arithmetic should go hand in hand, with abacus laying the foundation first and mental arithmetic being expressed in the second moment. When the difficulty of abacus increases, the progress will be slow, but mental arithmetic can be more unhindered and imaginative. Beware of the space of mental arithmetic, beyond the limit of abacus, that is, to reach the highest level of learners.

Not good. Let your child learn mental arithmetic.

The pros outweigh the cons.

Learning mental arithmetic is in line with the development of children's auditory vision and the laws of movement. Children are playful, curious, and intuitive. When learning mental arithmetic, abacus.

This concrete, intuitive and visual counting tool is not only a teaching aid, but also a learning tool and a toy for beginner children.

When children come into contact with the abacus, the beads are counted, and the beads are moved, just like a game, which is fun and attractive, and can cultivate a strong interest in learning.

At the same time, the abacus indicator counting is simple and bright, it learns the number by beads, and the file is positioned, and the hierarchy is clear; Addition and subtraction, subtraction and addition, multiplication and division are inverse, the arithmetic algorithm is clear and clear, and it is easy for children to learn and remember. In addition, mental arithmetic education in the middle ear.

Actions such as listening, seeing, oral reading, manual, lightning-fast counting and counting and inter-translation are all in line with the development and movement of children's auditory and visual vision, so they are easy to be accepted by children.

Disadvantages of mental arithmetic.

1. The unity of the algorithm and the previous stage algorithm is not high. As we all know, mental arithmetic is calculated from high to low, i.e., from left to right, while vertical calculation is from low to high, i.e., right to left. It goes without saying that there is a certain conflict between the two.

2. Children's patience problems. Learning mental arithmetic is boring, it is difficult for children to sit still, and parents need to be able to review and practice after class, otherwise the course will not be able to keep up. The close connection of the mental arithmetic course is very strong, and if you don't master the previous class, you can't keep up with the next class, resulting in a vicious circle, 3. Thinking inertia.

Pattern formation. Because the abacus is based on the proficiency of the abacus in the brain, and then forms a conditioned reflex.

It is a quick algorithm that directly calculates the results, so in order to learn mental arithmetic well, you must first be proficient in abacus. This will make some children who can already simply add and subtract mental arithmetic because they cannot be proficient in abacus and cannot form a bead diagram in their brains, resulting in inability to perform mental arithmetic.
