1. What is abacus calculation?

Answer: Abacus calculation is a method of adding, subtracting, multiplying, and dividing using an abacus as a calculation tool.

2. What is mental arithmetic?

Answer: Mental arithmetic is a calculation method that involves listening to or reading numbers through the brain's thinking, without the use of pens and calculation tools to calculate the results.

3. What is abacus calculation?

Answer: To put it simply, abacus calculation is to use an abacus in the mind. Abacus mental arithmetic is a method of adding, subtracting, multiplying, and dividing in the brain based on the abacus, which fully "internalizes" the operation process of abacus, completely breaking away from the external actions of actual planned abacus.

4. What is the difference between abacus mental arithmetic and other mental arithmetic?

Answer: Other mental arithmetic operations are carried out in the form of symbolic numerical concepts (mainly Arabic numerals) in the mind, which is a symbol processing process lacking intuitive and visual support. Therefore, the "internalization" process is incomplete, which affects the speed and accuracy of calculations.

Abacus mental arithmetic fully utilizes the advantage of the unity of abstractness and representativeness of symbols. Through programming language, operational methods, and repeated practice, the integration effect of human brain thinking is exerted, gradually breaking away from the limitations of physical movements such as actual abacus operations, and achieving a high degree of "internalization". The internal processing mechanism of its operation process is different from the special operation method of ordinary mental arithmetic, that is, the fully "internalized" "pearl like mental arithmetic.

5. What is the expression of abacus calculation?

A: The expression of abacus mental arithmetic is a kind of "Esperanto". When "pearl" 3 appears and becomes "pearl" 4, Chinese understand it, Malays understand it, Indians understand it, and people of other races also understand it.

Using this as a puzzle tool is unmatched by numbers. Abacus mental arithmetic is a logical thinking method that uses physical images, which is in line with the psychological characteristics of children.

The abacus calculation is consistent with the order of human thinking from a high position. The intelligent operation of the "virtual abacus" is a significant feature of abacus calculation, and using abacus in the brain enables students to develop excellent brain image thinking functions. Abacus mental arithmetic is a catalyst for promoting people's development from low-frequency thinking to high-frequency thinking.

6. What are the computational characteristics of abacus calculation?

Answer: The abacus calculation itself has the characteristic of calculating according to groups, which undoubtedly helps children who have difficulty mastering the concept of logarithms and overcome the phenomenon of children counting one by one.

The characteristic of the "five liter decimal system" possessed by abacus mental arithmetic greatly reduces the difficulty of rounding. The characteristics of the abacus mental calculation model are conducive to promoting the improvement of children's computing ability.

The operation of abacus calculation is a collaborative process of multiple sensory and motor organs, which requires the close cooperation of organs such as the eyes, ears, and mouth. Thus, it promotes the development of corresponding parts of cerebral cortex closely connected with it, and improves the intelligence level of children.

7. What is the relationship between abacus and mathematics?

Answer: Abacus calculation and mathematics are inseparable. Abacus mental arithmetic is a unique operational system based on mathematical principles and using an abacus as a tool to calculate numbers using beads. Mathematics is an abstract thinking activity, and in childhood, the ability to think abstractly was poor, making learning mathematics difficult.

Integrating abacus calculation into elementary school mathematics is beneficial for solving the difficult problem of learning mathematics during the enlightenment stage. In the current primary school mathematics textbooks, the tedious calculation process wastes a lot of primary school students' time. Practice has shown that the calculation of addition, subtraction, and multiplication in abacus mental arithmetic has saved about 50% of the amount of thinking, while division calculation has saved about 70% of the amount of thinking. The calculation of multiplication and division pays special attention to the simplification of "genes".

Numbers and beads are symbols. Abacus mental arithmetic only has three symbols, namely 1, 5, and 0; Mathematics has 10 symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The simplicity of abacus calculation is evident. The intuitive model of abacus can cultivate children's mathematical conceptual abilities, and the analytical model of abacus can help children understand the structural and quantitative relationships of applied problems, improving problem-solving abilities.

8. What is the operation process of abacus calculation?

Answer: In the process of abacus calculation, symbols are input and symbols are output. This process is actually a comprehensive process of observation, attention, memory, and thinking, and is also the result of the synergistic effect of sensory and motor organs such as the mouth, eyes, and hands.

Both abacus and mathematics use the "decimal" calculation method, and abacus only adds a "five liter system" for adjustment. The foundation of operations is based on addition and subtraction within 20, multiplication and division within a table. Some laws and properties in the four operations are applicable. The process of abacus mental calculation is a comprehensive application of three forms of thinking: logical thinking, visual thinking, and inspirational thinking, which can effectively promote the development of the overall brain function.

9. Should I use a pithy formula in teaching abacus calculation?

Answer: Should we use a pithy formula in teaching abacus calculation? Do you want to use mathematical concepts? There is no need to memorize or teach concepts such as "rounding up" or "filling up" that are difficult for children to understand. Instead, use a set of concise language to guide students in the operation of pulling beads.

In addition and subtraction, reduce the verb to "up", "to", "in", and "out". The multiplication formula is memorized by students in the form of a "pearl like multiplication formula table", which turns the originally cumbersome multiplication calculation into a simple and easy to learn method. The result is known at the first glance of the multiplication question, and everyone can learn it. The calculation of division is simpler than division, and the square root is clear at a glance.

The teaching of abacus mental arithmetic can achieve good results as long as it follows the principles of mathematics and follows the inherent laws of abacus mental arithmetic.

10. Do we still need to learn abacus in the computer age?

Answer: Some people say that with the rapid development of computer technology and information nowadays, learning abacus and mental arithmetic is not just a reverse? With airplanes, trains, cars, motorcycles, are bicycles still useful? Each has his own strengths and uses them.

Although computers are useful, time-saving, and accurate, they cannot become the cornerstone of mathematics. Abacus mental arithmetic is different, as it allows students to truly experience the entire process of calculation, which is a very important part of mathematics.

To learn mathematics well, one must understand the entire process of operations, only knowing the answer without knowing the reason is not conducive to the development of thinking ability. It can only be said that computers are a tool for computation, while abacus arithmetic helps to develop intellectual functions.

11. When did you start learning abacus calculation?

Answer: It is best to start learning abacus at the age of 4-9. From the perspectives of physiology and psychology, children of this age group mainly rely on visual thinking, while abacus mental arithmetic is a fast mental calculation method that utilizes the brain's spatial imagination and image reproduction ability to transform the abacus and its process of moving beads from physical objects and physical movements into thinking and moving beads in the brain. After adolescence, the optimal period for developing children's potential will be lost.

12. What teaching method is used for abacus calculation teaching?

Answer: Adopting the "abacus mental calculation teaching method". Its main characteristics include:

Firstly, teaching according to one's aptitude - with a wide range of teaching objects that everyone can learn;

Secondly, step by step - the teaching system is rigorous and can be consolidated step by step;

Thirdly, with the help of textbooks - intuitive teaching images, it is easy to teach and easy to learn;

Fourthly, pursue speed - the teaching effect is magical, and the human brain surpasses the computer;

Fifth, enlightening wisdom - innovative teaching methods make everyone smarter.

This teaching method has changed the previous teaching method of neglecting fingering and the law of changes in the image of the pearl, and has changed the clumsy and inefficient teaching method of requiring more than two hours of practice every day and 3-5 years to perform mental abacus calculation,

It has changed the traditional teaching method of cramming, cramming, and mechanically practicing sea battles. It is a new teaching method that involves learning through music, thinking through music, and practicing through music. It can help students consolidate one lesson and make progress in each lesson. It not only improves their computing ability, but also promotes whole brain thinking and intellectual potential development.
