In the teaching of solving problems for many years, it is found that students often make the following mistakes: 1, unable to examine questions; 2, will not analyze the quantitative relationship; 3. Interference conditions will not be handled. This is how I deal with solving students' problems. Guide students to think effectively in mathematics, and don't deviate from the teaching objectives of this class. It is normal for children to make mistakes. We should be good at protecting students' self-esteem and self-confidence, let children find the reasons and gains of failure in their mistakes, and guide them to find the correct ideas and methods to solve problems. Group cooperation is an important way of mathematics learning, and their communication style and innovation ability can not be ignored. 1, create a reasonable teaching situation, pay attention to solving the relationship between problems and real life, and let students truly realize that mathematics is closely related to real life, and mathematics is around us. There are many mathematical problems, ideas and methods in real life. Such as "shopping, renting a car, buying tickets,,," and other issues closely related to life. When students deal with these problems themselves, they will feel relaxed, but when these problems appear in textbooks for students to solve, they will feel headache and make mistakes in answering. The reason is that students' thinking is divorced from students' real life, so we should create a reasonable teaching situation in teaching, so that problems can be closely combined with students' real life.

Pay attention to the development of students' thinking and avoid letting students set up any mode to trap their thinking. The design of the new textbook pays attention to the expansion of students' thinking, and there is no "multiplication, multiplication" in the old textbook. Learn division and use division; I learned multiplication and division, but I don't know how to do it. The problem-solving of students is a process of self-exploration and application of knowledge, which requires teachers to provide students with a space for positive thinking and cooperation, so that students can think about problems in their favorite way in an open environment and promote the continuous improvement of students' problem-solving ability.

3. Seize the students' "mistakes" in time, throw them to students, and find out the breakthrough of mistakes. Students will inevitably make mistakes in the process of exploring and solving problems. We should not be afraid of students' mistakes, but should always try to correct them. We must seize the opportunity to throw the mistakes to the students, let them guess, discuss and communicate, find out the reasons of the mistakes in the communication, and correct them under the guidance of the teacher. This will get better results, because students will not make mistakes again in the future only if they know where they are wrong.
