First, focus.
Abacus mental arithmetic is a highly concentrated training method. In this course, children's attention will be mobilized by the height of digital calculation, not only eyes, ears and hands, but more importantly, children's brains should operate at a high level, thus deploying the body's senses. Gradually, the child's attention will be constantly cultivated.
Second, pay attention to breadth.
Abacus mental arithmetic can cultivate children's attention range, which is conducive to children's better observation of things and to children's memory. Entering school to learn Chinese is more conducive to the improvement of children's reading speed and efficiency.
Third, pay attention to persistence.
Learning abacus mental arithmetic course, with the increase of difficulty, each child calculates more and more numbers, from the addition, subtraction, multiplication and division of the first two or three numbers to the addition, subtraction, multiplication and division of the next ten numbers. In this process, children are required to have good attention persistence, otherwise the calculation of numbers cannot be completed. When children can successfully complete the requirements of multi-digit calculation, parents can find that the persistence of children's attention has been improved.
Fourth, attention is stable.
Only students with stable attention can maintain lasting thinking and form stable thinking ability. This kind of steady attention can be cultivated through continuous cultivation.
The final result of abacus mental arithmetic course is that it can be calculated quickly without abacus. Although divorced from the real abacus, students actually make quick calculations through the invisible abacus that appears in their minds. Then it is required that the abacus invisible in the mind is a stable brain image, otherwise, after calculating several numbers, once the image is unstable and fuzzy, the subsequent calculation cannot be carried out.
Five, hand-eye coordination ability.
The greater advantage of abacus mental arithmetic is that through such courses, children's senses will be better mobilized and their senses will be more balanced. In class, the teacher will let the children dial the abacus while holding a pencil, and calculate while watching. After the calculation, they should first liquidate and record the results. Therefore, the child's hand-eye coordination ability will get better and better.
Sixth, thinking ability.
Through the usual training and the translation of numbers and beads during mental arithmetic, children can have an image understanding of the three-dimensional object of mental arithmetic, and the process of mental arithmetic is actually a process of combining static and dynamic. At the same time, with the increase of calculation times, children's thinking has been effectively developed and expanded.
Extended data:
merits and demerits
Advantages: "abacus mental arithmetic" can change learning attitude and increase children's concentration. Learning abacus mental arithmetic often requires independent and focused thinking, which invisibly cultivates children's attention and memory.
Disadvantages: "abacus mental arithmetic" conflicts with primary school mathematics, and it is easy to get confused without practice. "Primary school mathematics is an operation mode from low to high, and abacus mental arithmetic is just the opposite of primary school teaching. First high, then low. This opposite calculation mode may have an impact on children's learning. After children learn abacus mental arithmetic, they can only use image thinking for mechanical calculation, and develop a relatively simple and passive learning style.
