So, is it useful for children to learn abacus?
First, children's learning abacus mental arithmetic is conducive to enhancing their memory.
Children learn abacus mental arithmetic by memorizing abacus in their minds, and then plucking beads in their minds according to formulas to calculate the results. In the process of calculation, children need to memorize numbers, formulas and results, turn numbers into beads, and turn formulas into operations of pulling out beads. Its essence is an image memory, which is conducive to enhancing children's memory.
Second, children's learning abacus mental arithmetic is conducive to improving their quick calculation ability.
Children's mental abacus calculation is to change the calculation formula into the calculation activity of dialing beads, which is vivid, simple to operate and convenient to calculate, especially when the number is large, it is much easier to calculate, which greatly saves time and is conducive to improving children's rapid calculation ability.
Third, learning traditional abacus mental arithmetic is not conducive to children mastering calculation methods.
Because abacus mental arithmetic is not widely used in kindergartens, it is only used in excellent classes, which is a feature and supplement. However, because the traditional abacus mental arithmetic needs children to remember formulas and emphasizes memory, the conventional calculation teaching method in kindergarten emphasizes understanding. Because of their different calculation processes and methods, conflicts often occur, which makes children at a loss and is not conducive to children mastering the conventional calculation methods learned in kindergarten.
Fourth, learning modern abacus mental arithmetic helps children master the calculation method.
Because the traditional abacus mental arithmetic emphasizes memorizing abacus mental arithmetic formulas, which is inconsistent with the calculation principles of number-based synthetic addition and decomposition subtraction taught by kindergartens, it is not respected by kindergarten teachers and has little influence on parents of young children. Therefore, in order to cooperate with kindergarten teaching, the traditional abacus mental arithmetic has been reformed drastically, and the abacus beads are divided into red and green along the diagonal of the abacus box. In this way, the 65,438+00 beads in each column are divided into red and green parts. With the change of the number of red and green beads, different decomposition formulas of 65,438+00 can be written. In this way, abacus mental arithmetic is organically unified with the teaching methods in kindergartens. It can be seen that children's learning abacus has advantages and disadvantages. The key is to distinguish the calculation method of mental arithmetic, and parents should be careful when choosing to report their children to excellent classes.
