Brushing questions is only a necessary condition for primary school students to improve their math scores, not a sufficient condition. In other words, if primary school students want to improve their math scores, they must brush the questions. Brushing questions is one of the many important conditions for primary school students to improve their math scores. However, just brushing the questions does not necessarily improve the math scores absolutely. Because in order to really make primary school students improve their math scores efficiently and stably, primary school students must know the answers and reasons of math problems. Because some students have brushed a lot of questions and can only do some of the same type of questions, but they rely on imitation. If they do more questions of the same type, they will draw spoons according to the gourd and get familiar with their hands and ears. Once the problem is set (problem condition) or the problem is broken (problem conclusion) or both are slightly changed, only the person who brushes the problem may be dull and at a loss. Almost all primary school math teachers are used to brushing questions. If this model can't improve math scores, it is absolutely untenable. Otherwise, the math teacher can't use this method as a review means.

However, from the perspective of learning thinking and learning methods, the final review of mathematics is by no means the most effective way to improve mathematics performance, because mathematics is a highly applied subject, which can be said to be the most closely related to life. Therefore, I have always stressed that mathematics learning must establish a life-oriented learning thinking. The final exam is the last important task of every school. Teachers should evaluate and students should report their grades. Who dares to ignore it? "Examination is a magic weapon for teachers; Scores are the lifeblood of students. " So brushing your teeth is the same as washing, and you enter the final brushing mode. Brushing questions, from classification to comprehensive training, can review the past, understand new things, establish a problem-solving model, form a knowledge system, find problems, check leaks and fill gaps, and have many benefits. Some smart students don't want to do problems, and their grades may not be particularly good; Some middle school students get particularly good grades through more practice. Mathematics problem is the carrier of mathematics learning. Children have math homework every day. By doing the questions, you can see whether the child has mastered any knowledge and content. In fact, it is a process of knowledge application. From learning to understanding is a process of internalization and application.

Mathematics is the characteristic of spiral curriculum system, which has strong systematicness and continuity. The content of each stage is very important, which is the basis of the next stage of learning. Taking calculation as an example, primary school mathematics experienced four integer calculations, and the digital domain gradually expanded, and finally it reached the mixed calculation of elementary mathematics and fractions in senior grades. From the perspective of systematic learning, grade one and grade two are the basic stages of addition, subtraction, multiplication and division, and grade three begins to be transformed into column calculation. The fourth grade pays more attention to the flexibility of calculation, and the calculation ability of the whole primary school is also an important foundation of junior high school. With the growth of age, after entering the third and fourth grades, especially after the fifth and sixth grades, the learning content has changed and the difficulty has increased. At this point, students' scores have a floating process, which is related to the difficulty of learning content. In order to improve children's grades, it is necessary to do appropriate questions to improve them. Doing problems is not necessarily a lot of brushing. Brushing can make you perfect, but it takes more time. You need to pay attention to improving the quality of doing problems and adopt different strategies according to different situations.

Do the questions with pertinence, and carefully complete the homework tasks assigned by the teacher. Teachers usually arrange some typical questions for students to train, consolidate what they have learned and improve their learning ability. When doing homework, you should learn to think, be good at analyzing problems, pay attention to the characteristics of problems, and find the rules to solve them. Don't deal with problems at will, such a learning attitude is incorrect. In pursuit of quality in doing homework, we should not only finish homework, but also seriously think about homework. Teachers will also correct their mistakes, seriously reflect on their own mistakes, find out the causes of mistakes, learn to draw inferences from others, and master the corresponding knowledge points. In short, primary school students need some training to improve their academic performance, but it is not advisable to do problems blindly. In different grades, combined with the characteristics of each stage, learning should be targeted, carefully complete the homework assigned by teachers, be good at thinking and questioning, learn to summarize and reflect, improve the ability of examination and verification, and strive to continuously improve academic performance.
