Abacus mental arithmetic requires children to form an abacus in their brains, and empty the abacus to get the answer.
Abacus mental arithmetic is mechanical memory, which relies on rote memorization and the accumulation of training. Practice makes perfect. Will limit the child's brain development. Primary school mathematics is to let children understand mathematics and solve problems, and rote learning is not recommended.
Abacus mental arithmetic does not have the concept of logarithm, but starts from a high position, while mathematics education in primary schools starts from a low position. The conflict of teaching methods will confuse children.
In order to reach the point where practice makes perfect, abacus mental arithmetic needs a lot of time and energy to study and practice every day. Once the training is terminated, the mental arithmetic ability will gradually decline or even disappear.
Abacus mental arithmetic is suitable for children above grade three in primary school; The Ministry of Education does not encourage students below grade three to study.
When a child goes to primary school, the calculation method taught by the teacher conflicts with the calculation method of mental arithmetic, which will make the child at a loss. Who is right? Primary education is exam-oriented education, and what needs to be done is written examination. And mental arithmetic is often calculated while listening. Teachers report questions and students report numbers. Don't forget that exam-oriented education has time requirements. For example, 5 minutes 100 (addition and subtraction within 10), mental arithmetic is slow on the one hand and low on the other.
Gao's parents: My daughter studied abacus mental arithmetic for one semester. Maybe girls are not interested in numbers, and the learning effect has not been very good. After primary school, she often told me that primary school teachers teach abacus mental arithmetic in different ways. I told my colleagues about this situation. Colleagues said, why don't you learn from Kong Le's children and do mental arithmetic quickly? Take my son for example. In the past, you used to do arithmetic with your fingers broken and often made mistakes. Now, you can answer questions with a pen without snapping your fingers. It's fast and accurate. After hearing what he said, I made a quick mental arithmetic for my daughter, not to mention the effect was really good.
Wang Xuefang's parents: My son learned abacus mental arithmetic, and now he won't leave the abacus. When he was in kindergarten, he had to go to primary school. He is not allowed to use an abacus when calculating, and his grades are in a mess. You can even say that it is not at all. I don't even think I have learned anything from abacus now. The teacher said that it is best to fail the child in this situation. I don't think it is possible to fail. My husband came back and told me that his colleague's daughter had made rapid progress after learning fast mental arithmetic. I gritted my teeth and enrolled my son in the Kongle children's quick mental arithmetic class. Halfway through the study, the child's grades went up and he got rid of the talons of mental arithmetic. Some bad study habits have been corrected.
Hand-brain quick calculation is also called finger calculation or hand-brain calculation. The teaching method is to use hands instead of beads. The arithmetic method is the same as abacus mental arithmetic. Judging from the addition and subtraction within 10 learned by children after primary school, the effect is very good and the correct rate is very high. But after setting a good time for the children, more than 80% of the children failed. In the final analysis:
In early childhood, children's brain image thinking is dominant and highly dependent on things. Hand-brain fast calculation uses hand as an operation tool to get the answer. Without the concept of number, it has the same disadvantages as abacus mental arithmetic, and it also depends on rote memorization. Practice makes perfect. Do not pay attention to cultivating children's understanding of logarithmic concepts.
Fast calculation of hand and brain requires children to break their fingers constantly when calculating questions, and then answer after counting their fingers, which wastes a lot of time in counting their fingers. As a result, there is not enough time and the results are unqualified.
The math professor said: Quick calculation with hands and brains is the worst teaching method, which can cultivate children's worst study habits. Let children have a strong dependence on fingers, which is not conducive to the development of children's brain intelligence and will cause mental retardation.
Parent Zhong: My child learned to do quick calculations with his hands and brain in kindergarten, but I don't want to mention how happy I am to learn arithmetic. Now that I am in primary school, problems appear one after another. In elementary school, each finger stands for 1, but what the kindergarten teacher taught me is that the thumb stands for 5 and the other fingers stand for 1. Children don't know how to calculate problems, because they don't know which teacher teaches them right. Another problem is that when calculating problems, I have to use my fingers to calculate. I can understand when I was a child. After all, children are still young. Now they are in primary school, and they still have to count with their fingers. This is even the key. It's still wrong to be slow. There is a nameless fire in my heart. Let me see ~ after all, it's my own daughter. She made it herself. I asked the parents whose children got good grades, but none of them learned to do mental arithmetic quickly. A parent shared it with me and asked my daughter to learn the quick mental arithmetic of children in Kongle. I signed up and studied for a while, and the effect came out. I use my fingers less and less, and I never use my hands to index again. Now I do my math homework quickly and accurately.
Rey's parents: My child also learned to calculate quickly in kindergarten. I was so happy at first, and now I'm in primary school, but fortunately I'm still angry with him. I break my fingers every day and make mistakes. I'm so angry that I don't play anymore. In order to get rid of the bad habit of counting fingers, I started to fight when I saw him counting fingers. This can't be changed. I count it secretly with my fingers behind my back. My son's wronged eyes really make me regret letting my children learn to calculate quickly.
1. Montessori's mathematical logarithm concept is particularly strong and very close to life. Children's hands-on operation runs through the whole teaching process, freeing children from the bondage of traditional teaching. Let children's thinking ability, hands-on coordination ability, imagination and observation ability be greatly developed.
2. The disadvantages of Montessori mathematics are also obvious. When adding and subtracting multiple digits, it is impossible to calculate without physical objects.
Experts suggest that Montessori mathematics helps children to lay a solid foundation in the concept of numbers, and the combination of children's quick mental arithmetic and Confucius will solve the disadvantages of Montessori mathematics. The combination of quick mental arithmetic and Montessori mathematics can get twice the result with half the effort.
The quick mental arithmetic of children in Kongle starts with the most basic concept of number, which is closely connected with primary school mathematics. The teaching method is simpler, easier to learn and easier to absorb. In teaching, we can simply deal with complex problem information and visualize abstract mathematical concepts.
Kongle children can do mental arithmetic quickly without any physical help, which is well connected with primary school mathematics and solves many parents' problems for many years. It clears the way for children with math difficulties in primary schools.
The teaching method of integrating mental arithmetic, oral arithmetic and written arithmetic promotes the all-round development of children's brains and lays a solid mathematical foundation. Develop lifelong and efficient learning methods.
Use the calculation method of primary school mathematics, starting from the low position. Even if it is a multi-digit addition and subtraction, the idea of solving the problem is clear and clear.
Fast mental arithmetic is not only calculation, but also attaches great importance to cultivating children's understanding of logarithmic concepts.
Confucius' Happy Heart for Children is compiled by inviting famous professors from Zhejiang University, picture books of children's psychology and famous front-line educators according to children's psychological and intellectual development curve and primary school syllabus, which conforms to children's age characteristics and needs. It has played a very good role in mathematics enlightenment education.
Kong Le children's quick mental arithmetic pays attention to children's experience of logarithm in daily life. In the course, the teacher will combine the events in life to improve the children's understanding of the concept of logarithm. Pay attention to the teaching mode of playing in school and playing in middle school.
Kongle children are quick-witted, young people are good partners, and young people around you are good helpers. National patent, brand on CCTV list.

Children's quick mental arithmetic starts with the most basic concept of number, which is synchronized with primary school mathematics, but the teaching method is simple and easy for students to accept. In teaching, quick mental arithmetic simplifies complex problems and visualizes abstract mathematical concepts. Children's habit of counting fingers has made a good transition with elementary school's oral calculation. It has solved the problems that parents and teachers have not solved for many years. It clears the way for children to learn oral arithmetic well. There are no physical objects (including fingers).
Summary: To sum up, judging from the teaching effect and the situation of connecting primary schools, in the aspect of children's mathematics enlightenment, Kongle children's quick calculation heart is the most suitable quick calculation course for children's connection.
