The reason why children are not advised to learn abacus mental arithmetic is in conflict with primary school mathematics, and it is easy to get confused if they don't practice. Mathematics in primary school is an operation mode from low position to high position, while 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.
Introduction to abacus mental arithmetic The so-called abacus mental arithmetic is abacus mental arithmetic. Abacus calculation is a calculation method that uses abacus as a tool to perform operations such as addition, subtraction, multiplication, division and square root. There are certain rules and formulas in the skill of transporting beads. When the user can skillfully operate the abacus, he can not only get the correct answer quickly, but also describe the disk type, grade and floating change of the abacus in his mind through the growth of brain cells. This vivid abacus image is called "virtual disk". It completes abacus calculation in the brain through the process of perception, image and memory, which is what we call abacus mental calculation.
Abacus mental arithmetic does not exercise children's logical thinking ability, which is completely different from traditional algorithms. The principle of abacus mental arithmetic and palm arithmetic: Step 1: Convert numbers into beads or actions. Step 2: the relationship between numbers becomes the relationship between beads and the relationship between actions, and the result of beads or actions is obtained. Step 3: Convert the result of the relationship between beads, actions and actions into the final number.
Why can children master it so quickly? That's because these algorithms stop thinking on the basis of action thinking and solidified image thinking, which is not conducive to developing children's logical thinking ability and mastering real mathematical concepts.
