When I was in college, I signed up for a club, that is, I went to the library every day to sort out the books, and put the books borrowed by other classmates back to their places, and other club members needed to find them in a row, so I remembered it all at once, and then went straight to the destination, haha, and memorized texts in high school, that was my strength! Every time I write ancient poems silently, it's a bargain! None of them have been deducted.
If you count, I can only say that I took the college entrance examination mathematics test 141, overall, I think it's OK, it's worth learning This is my personal feeling, but everyone's ideas are different.

Contributes to right-brain development. Mental arithmetic is outlined in the brain, which is more helpful for memory and training concentration. Accuracy can only be guaranteed in the case of a high degree of concentration.
-
Children's mental arithmetic is more sensitive to mathematical thinking, and children set subjects. It is the transformation of physical and abstract numbers by the scholar himself. In order to calculate faster, it is calculated from high to low.
Grade 1 math calculation mainly understands how to calculate the digits of individual, ten, hundred, and thousand, which is just the opposite of mental arithmetic counterpoint calculation, and the writing method also starts from the single digit.
-
Mental arithmetic is an arithmetic technique, which is just a point for mathematics. Learning mental arithmetic in primary school does more harm than good and does not have any substantive effect. After learning mental arithmetic, there is a great conflict with the learning of mathematics in the current teaching system, and the child will no longer use the calculation methods of the textbook, resulting in a poor foundation in mathematics, so that the mathematics score is over.
-
I would like to say that it is a bit hard to learn this, but it is better to be interested in it. But I did personally benefit a lot. To put it simply, the math in the exam does not need to be ...... scratch paper at allTurnaround speed is blazing.
-
Enhance interest in learning. The fun of mathematics can also be extended a lot. For example, the abacus is the essence of traditional culture, and the skillful use of it can surpass the calculator.
-
My own child learned mental arithmetic in kindergarten, and I followed it for one semester in the first semester of one year, and it should be the next semester and the next semester. Abacus is no longer registered. Personally, I think that you can get in touch with learning before the first grade, and if the child performs well after learning, parents can continue to learn.
If the level of mastery is normal, parents are asked to move the education center to other aspects, because the child has a lot of content to learn, and the learning of mental arithmetic only plays a small role.

Some people say mental arithmetic.
The pros outweigh the disadvantages, and children's learning mental arithmetic will have an impact that will harm their interest. The algorithm is not consistent with the previous algorithm. As we all know, abacus.
is calculated from high to low, i.e., from left to right, while vertical is from low to high, i.e., right to left. It goes without saying that there is a certain conflict between them. Learning mental arithmetic is relatively boring, and it is difficult for children to sit still, so parents need to review and practice after class, otherwise the course will not be able to keep up.
Learning mental arithmetic will have a certain effect on exercising the fingers and brain, and fast calculation is conducive to improving the baby's self-confidence.
1.Mental arithmetic can also guide children to form habitual thinking.
When children learn abacus, they will develop the habit of calculus in their heads. For some children, they may have mastered simple addition and subtraction, and it is difficult to develop a habit of learning in their heads.
As a result, these children may not learn abacus. If your child really wants to learn abacus, it's not impossible. As long as you master certain principles, you can fully grasp the advantages of mental arithmetic.
2.Because mental arithmetic is a fast algorithm based on the proficiency of mental arithmetic, and then forms a conditioned reflex, the result can be obtained directly through mental arithmetic, therefore, to learn mental arithmetic well, you must first master the skills of mental arithmetic. This will make some children who can only add and subtract mental arithmetic proficiently and form a bead diagram in their minds, resulting in the inability to perform mental arithmetic.
3.Only if the child is interested in mental arithmetic can he work mental arithmetic. Interest is the best teacher for children's learning.
When children are interested in something, they are also willing to pay attention to it. Therefore, if children want to learn abacus, they must adhere to the principle of entertaining and teaching. There are some differences between the children.
In the process of mental arithmetic education, different integrated education should be carried out according to different emphases.
If the child is happy in the process of learning, even if it is a little bitter, it can make the child persevere. The above is the answer to the question of why some people say that the advantages of mental arithmetic outweigh the disadvantages, and what will be the impact of children learning mental arithmetic.
-
Because this calculation method can improve children's hearing and visual ability, can cultivate children's development rules, and then can also grasp the characteristics of children's curiosity and fun, can improve children's mental arithmetic ability, and then let children understand life more intuitively; However, it may lead to stereotypes in children, which may affect children's patience. It is not consistent with the current teaching method.
-
Because mental arithmetic is in line with the laws of children's development. Through some interesting courses, children can improve their attractiveness and learning ability, so as to cultivate a good interest in learning and life. Learning mental arithmetic will speed up students' arithmetic.
It is very beneficial for future study life. It is of great benefit to the development of students' thinking in the early stage of learning.
-
Because mental arithmetic conforms to the development of children's visual, auditory and motor development, its advantages outweigh its disadvantages; It will help children's arithmetic to be faster, and secondly, it can also make brain development better, hands-on ability, and stronger ideological concepts.
-
Because mental arithmetic can exercise a person's arithmetic ability, it is good for children's brain development, and children can become smarter and more mathematical and logical thinking when they learn mental arithmetic, which is conducive to children's intellectual development.
-
I think that letting children learn mental arithmetic will do more harm than good, especially if the child himself does not like to learn mental arithmetic, then the disadvantages are obvious.
Disadvantages of mental arithmetic:
1. The unity of the algorithm and the previous stage algorithm is not high. As we all know, the calculation method of mental arithmetic is from high to low, that is, from left to right, while vertical calculation is from low to high, that is, from right to left. It goes without saying that there is a certain conflict between the two.
This kind of conflict will bring some trouble to the mathematics teaching in the lower grades of primary school, which is not conducive to children's self-confidence in mathematics.
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 mental arithmetic course is very closely linked, and if you don't master the previous class, you can't keep up with the next class, resulting in a vicious circle, which leads to children's aversion to mathematics.
3. The formation of thinking inertia mode. Because abacus is a quick algorithm that plans to make a disk in the brain on the basis of being proficient in abacus, and then forms a conditioned reflex and directly obtains the result of mental arithmetic, therefore, in order to learn abacus 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.
4. The destruction of mathematical thinking. Mathematics is based on logical thinking, and a complete system is formed through logical deduction, and mathematical thinking is a way of thinking. Mathematics is not a simple addition, subtraction, multiplication and division, nor is it a simple calculation of breadth, it is abstracted from real life.
The abacus emphasizes calculation and does not allow children to understand numbers and mathematical thinking first, and if preschool children learn, it is easy to destroy children's mathematical logical thinking.

What are the pros and cons of children learning mental arithmetic? Mental arithmetic is a method of learning mathematics that enables you to quickly calculate basic mathematical addition, subtraction, multiplication, and division. Nowadays, many children are learning mental arithmetic, so what are the pros and cons of children learning mental arithmetic, let's take a look.
What are the benefits of children learning mental arithmetic?
1. Use both left and right hands to promote the balanced development of children's left and right brains.
2. Eyes, ears, hands, mouth, and brain participate at the same time, effectively cultivating children's attention, memory, observation, imagination and thinking ability.
3. Make children's computing ability improve rapidly. But don't let your child take this as a burden, the key is to cultivate his interest and lay a good foundation for the future.
4. It inspires the baby's enthusiasm and initiative in learning. Another characteristic of babies is that they are active and competitive. When learning mental arithmetic, babies sometimes read, report, sometimes plan to disk, sometimes listen to the calculation, look at the calculation, sometimes the result, but also interspersed with group competitions, to see who reports the number quickly, accurate calculation, so that the baby is always in a positive state of mind and the initiative to learn.
Mental arithmetic is suitable for the characteristics of the baby, inspiring the baby's enthusiasm and initiative to learn, they are learning in motion, cultivating brain function, making the baby more intelligent.
What are the disadvantages of children learning mental arithmetic:
1.Cause learning pressure At this stage, children's learning pressure is already very great, and the learning of mental arithmetic will bring great learning pressure to children, because many children learn mental arithmetic in their free time, which will occupy children's rest time and put pressure on children's bodies and spirits.
2.Produce a comparison mentality. The so-called comparison mainly refers to the purpose of children learning mental arithmetic, most of which is to win awards and surpass other children, which violates the original educational purpose of mental arithmetic learning and will make children compare in the process.
3.Forming a rigid mindset. When children learn mental arithmetic, they will sit fixed for a long time, which will make children's thinking always be in a fixed thinking mode, which is not good for children's bodies and is not conducive to children's divergent thinking exercises.

The benefits of learning mental arithmetic
1.Improving Computing Skills Abacus mental arithmetic is a kind of computing ability training, children in the learning of mental arithmetic, through focused learning, can be a good way to improve children's computing ability, so that children can easily cope with general calculations.
2.Improve comprehensive ability.
Children in the learning of mental arithmetic, can carry out comprehensive ability training for children, is conducive to improving memory ability, cultivating attention, the speed of mental arithmetic, the accuracy of the level, the key lies in the abacus in the brain.
The length of time, the depth of the traces, and so on.
The disadvantages of learning mental arithmetic
1.Children can't be careful For young children, it is very difficult to be careful, so if it is not a very good education, it will make the child unable to sit still and make the child more irritable.
2.There is a gap between the learning of abacus and the learning of abacus, so the learning of mental arithmetic by children will, to a certain extent, allow the brain to calculate and form a conditioned reflex.
It will have an impact when your baby is learning abacus.

Summary. Hello, learning mental arithmetic well, of course, has a very positive impact on the subsequent mathematics learning. Calculations are faster and more accurate.
Hello, learning mental arithmetic well, of course, has a very positive impact on the subsequent mathematics learning. Calculations are faster and more accurate.
Poor for first-year divisions.
Isn't it. Is the child just in the first grade?
Be. OK. But don't take up too much of your child's energy. You can practice this skill by laying a good foundation of hand arithmetic first.
Uh-huh, is this bead count taught outside of class? Master the knowledge in our textbooks first, and learn first according to the teacher's instructions. Otherwise, it will be confusing.
This question is not contradictory. Learn the teacher's course in the classroom first, because if you have to take the exam, you have to follow what the teacher teaches. When you have the ability to learn, learn this skill again.
Just like the teacher talks about driving a car in class, you learn to fly an airplane, although they are all at the destination, but the exam is to drive a car, no matter how good you drive the plane, the exam is not that.
The playful nature is only part of the reason. Personally, I think that the family and school environment are also related. Generally speaking, children can forget all the things that are not entertaining in reality when they play, so in reality, if children study or parents give pressure or worry a lot, they will go online, and they will not be able to get out for a long time. >>>More
You can refer to the second season of Where Dad Goes.
It's mainly fun, or children don't want to learn, and then it's interactive and stuff, so it's easier for them to remember, and it's important to teach outside the class! Don't let your child speak Chinese English accent when he is exposed to English My child is in Libu children's education, I think it's okay
There are many reasons why small children eat vomit:
For example, it does not fit the taste. >>>More
Sanda is not recommended, although I practice sanda, because sanda is too practical and suitable for adults to practice, at least high school students.
