The main difference between children's finger speed algorithm and traditional finger counting operation is the counting method. In the finger speed algorithm, fingers represent not only the number of elements, but different fingers represent different numbers through its rules, and there is no one-to-one correspondence. For example, the right thumb stands for 5, and the remaining fingers stand for 1. If you add the index finger, middle finger, ring finger and little finger respectively, it means 6, 7, 8 and 9, and the left thumb means 50; if you add the index finger, middle finger, ring finger and little finger respectively, it means 60, 70, 80 and 90. Then, combine the different numbers represented by the fingers of both hands for operation.
At present, children's finger speed algorithm is widely used in children's mathematics education, and some kindergartens offer children's finger speed calculation courses or position them as teaching characteristics. It can be affirmed that the pointing speed algorithm has played a positive role in the process of children's mathematics education. Children are interested in this method, which can better mobilize the enthusiasm of children to practice addition and subtraction. Moreover, this method requires children to calculate by brain and index by hand, and needs a certain degree of image and imagery thinking, which has a positive effect on improving children's abstract thinking ability. However, in the process of applying this method, if it cannot be effectively combined with children's mathematical cognitive level and applied at a suitable cognitive level, it will have a negative impact. Therefore, in the specific application process, we must correctly handle the relationship between the application of this method and children's mathematical cognitive process to avoid going into misunderstanding.
