First, clear the importance of junior high school mathematics calculation
Calculation is the basis of learning mathematics. Although some students have mastered the calculation method, they often make mistakes in the calculation. This not only directly affects the learning effect of application problems and application problems, but also seriously hinders the improvement of students' math scores. It is beneficial to life to learn the basic knowledge of numbers and calculations well and form a certain computing ability.
Second, understand the reasons for the low calculation accuracy.
When students are asked to analyze the causes of wrong questions, most of them are caused by carelessness. What are the reasons for "carelessness"? On the one hand, students' psychological quality is not mature enough, on the other hand, they have not developed good study habits. Some students' calculation accuracy is not very high, which may have little to do with the number of times they usually practice. It may be the lack of a good calculation habit, such as checking the calculation habit, and ignoring the role of "estimation".
Third, improve the accuracy of junior high school mathematics calculation methods
Junior high school students need to understand the problem-solving methods, review in class after completing a topic, repeat the problem-solving ideas, and copy the wrong questions. After a period of hard work, the problem-solving error rate will be reduced and good study habits will be developed.
1. Pay attention to the calculation
I have always thought that calculation problems are much easier than the analysis of application problems, and I have a solid understanding of some laws and laws, so calculation is a breeze, so I am either too confident or unable to concentrate when calculating, and the results are full of mistakes. In fact, it is not easy to calculate correctly. In this complicated process, a little carelessness will make the calculation of the whole problem wrong. Therefore, the calculation must not be sloppy.
2. Abide by the calculation rules
When calculating, you need to find out the meaning of the question and see if there are any special requirements such as simple method and keeping several decimal places. The operation sequence needs to be determined. On this basis, relevant rules and laws are adopted for calculation; We need to check carefully to see if there are any mistakes, omissions and calculation errors.
Calculate carefully
Some students make mistakes because they are not careful in calculus. The data is unclear and the identification is wrong. When drafting, you can't arrange the vertical tables in a certain order, which leads to the adhesion between the top and bottom, the misalignment of the same numbers, which is not convenient for inspection and easy to read the wrong data.
Correct and fast calculation is the most ideal goal, but it is the premise and the most basic requirement to know correct calculation. Every homework that students need to do is equivalent to an exam. You can't make mistakes in quizzes, but you can reduce mistakes in big exams.
