Why the country does not advocate bead counting

Why the state does not advocate bead calculations for the following reasons:

1, because the bead calculations will be young children's representation of the solidification of the hand-brain calculations will be young children's thinking stagnation in the action, the young children, is the degradation of the development of the mind or inversion of the scientific teaching of mathematics is contrary to the child is not conducive to a true understanding of the concept of number.

2, because the bead counting algorithm and the first stage of the algorithm unity is not high. The bead counting method is from high to low, i.e. left to right, while the vertical counting is from low to high, i.e. right to left, and there is a certain conflict between the two.

3, because the bead counting is from the high position to add up, the hand-brain counting by a specific action characterization. This is detrimental to the child's learning of vertical addition and subtraction as he enters the second grade of elementary school.

4. The use of bead counting leads learners to lose sight of the meaning of the numbers themselves, because the meaning and value of numbers is much more than just their use in arithmetic, but also in imagination.

Bead counting benefits:

1, practicing bead counting is good for enhancing the memory of young children.

Bead calculator is to memorize the abacus in the brain, form the bead image map, and then according to the arithmetic formula in the brain to dial the beads to calculate the results of the calculation process, memorize the numbers, the arithmetic formula and the results of the figures into beads, the arithmetic formula into the dial beads of the operation activities, the essence of the image of the memory, conducive to enhance the child's memory.

2. Learning bead counting is conducive to improving the ability of quick counting.

Bead counting is intuitive, image, easy to operate, convenient to calculate, especially when the number is large, it is much easier to calculate, greatly saving time, and is conducive to improving the ability to calculate.

3, in line with the development of children's auditory-visual and motor law.

Children are characterized by fun, curiosity and intuitive understanding of things. Learning bead counting, the abacus this specific, intuitive, image counting tool for the first learning children, both teaching aids, and learning tools, but also toys. When they come into contact with the abacus, the bead dialing is counted, the bead movement is counted, like a game, fun and attractive, can develop a strong interest in learning.

4, inspire children's learning enthusiasm and initiative.

Another characteristic of children is that they are active and aggressive. Learning the process of bead counting, sometimes read, report, sometimes plan to disk, sometimes listen to the calculation, see the calculation, sometimes answer the results, but also interspersed with group competition to see who reported the number of fast, accurate, so that the children are always in a positive state of mind and the active position of learning.

Bead counting bad:

1, learning traditional bead counting is not conducive to mastering the calculation method.

Because bead calculations and modern math teach different calculation processes and methods, often in conflict, so that students are at a loss, not conducive to the students to master the conventional methods of calculation learned in the classroom

2, the child's patience problem.

Learning bead calculations 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 close connection of the course is very strong, the last class did not master, the next class will not be able to keep up with the formation of a vicious circle.
