First, we should cultivate students' good consciousness of paying attention to the accuracy of calculation results in peacetime teaching. In teaching, when analyzing the causes of students' exercise errors, they often only pay attention to the strategy of solving problems, but seldom pay attention to the calculation errors, which are always thought to be caused by children's carelessness. However, the high error rate of students' calculation often affects the quality of homework and assessment. Teachers must find, criticize and correct the repeated calculation mistakes that students often make, so that students can get enough attention. Teachers should praise students with accurate calculation results in time and promote the improvement of students' calculation ability with the power of example.
(2) Help students check the reasons and improve the accuracy of calculation. Each calculation has corresponding basic knowledge such as concepts, rules, properties and formulas. In the usual teaching practice, due to various reasons, students' understanding of arithmetic is not thorough enough, which brings great obstacles to the improvement of computing ability. At this time, teachers should be good at finding out the causes of students' mistakes, making use of the situation to help students overcome the difficulties in calculation and improve the accuracy of calculation. For example, in the division calculation, when is there a 0 in the middle of the quotient? When students make the formula of 7 14÷7, the dividend of 7 can be divided by the divisor of 7, but the dividend of 1 cannot be divided by the divisor of 7, so it needs to be quotient 0, and then the dividend of 1 and 4 are combined and divided by 14. Of course, not only division has arithmetic and skills, but also other operations. Only by making students understand these calculations clearly can the accuracy of students' calculations be fundamentally improved.
Third, cultivate students' good writing habits. Good writing habits are also the true embodiment of students' computing habits. If a student's homework is written neatly, the accuracy of calculation is relatively high. Therefore, in the usual teaching, we should put forward strict requirements for students' writing. First of all, we should copy the numbers and operation symbols correctly, and then we should look at the questions clearly and calculate them carefully. For some topics with large numbers, the vertical arrangement must be listed on the draft paper, while for the calculation of the off-arrangement, it is necessary to see, think and calculate. In addition, it is necessary to train students to develop good exam and exam habits.
In a word, the cultivation of students' calculation accuracy is a complicated and meticulous work, which can not be completed overnight, and needs long-term cultivation and training combined with teaching practice. As a teacher, while teaching students calculation methods, we should pay attention to cultivating students' interest in calculation and enhancing their self-confidence in learning mathematics well. As long as we persevere and make unremitting efforts, the calculation accuracy of students will be greatly improved.
