Computing ability is the most important ability in mathematics. Because the operation looks simple, easy to answer and easy to be ignored, there is a situation that you can do it at a glance and make a mistake at once. In the process of tutoring students, it is found that most students have some problems in calculation, which are mainly reflected in two aspects: first, the calculation speed is slow, especially the ability of oral calculation and mental calculation is poor, and second, the accuracy of calculation problems is poor, especially the comprehensive operation, and there will always be problems in method and order. ?

First, insist on making a verbal card every day to cultivate children's strong computing ability. In mathematics, a child must have strong computing ability if he wants to get high marks and perfect marks. If the child's calculation ability is poor, the score will not be too high. Children's computing ability should be cultivated from an early age. From the first grade, they will insist on doing mouth card calculation every day, regularly, quickly and accurately. If there are many mistakes, they can add another mouth card calculation to consolidate the exercise. Persistence will cultivate their powerful computing power.

Second, master the algorithm, operation sequence, operation speed and simple operation. Primary schools involve addition, subtraction, multiplication and division of integers, decimals, fractions and percentages. After children master the calculation methods and skills, they can strengthen their practice and achieve the effect of consolidating knowledge points. For example, children can recite the reciprocity of scores, decimals and percentages in general exams, which can improve the speed of doing problems and save time. This is also a skill and method. In addition, we can also use the operation rate, deformation and other methods to carry out simple operations, such as rounding up, rounding up to zero, combining denominator scores, etc., so that we can improve our calculation ability when we are proficient in regular exams.

Third, be good at summing up. When there are mistakes in homework and test papers, we should analyze the reasons for the mistakes, such as forgetting to borrow carry, wrong symbols, wrong operation sequence, wrong numbers, etc. And sort out the wrong questions in the wrong book, do it again, write two or three questions of the same type, and then consolidate the exercise, so that you will master it more firmly;

Finally, if children can persist in doing oral calculations every day, be good at summing up and reflecting, sort out wrong questions, and persist all the time, they will certainly have strong computing ability. Come on! I summed up the simple operation of the operation rate and the common test for my children, and the relationship between the scores, decimals and percentages of the common test. Let's collect it for children!
