In teaching, we should proceed from the reality of life, cultivate students' ability of judgment and analysis, and guide students to develop good habits of listening attentively, carefully examining questions, thinking independently and solving problems. I ask students to adhere to the five steps of "reading, finding, thinking, calculating and answering" every time they do an application problem. That is, first, read the questions accurately three times; Second, we must find out the conditions and problems; Third, we must think about the algorithm; Fourth, the calculation should be correct; Fifth, answer. [Keywords:] Problem-solving steps require the habit of examining questions and the ability to judge and analyze problems. In primary school mathematics teaching, application problems occupy a considerable proportion. Simple application problems are the beginning for primary school students to learn application problems. For the second-grade students in primary school, to answer the application questions accurately, they must work hard to improve their problem-solving ability and lay a solid foundation for learning complex application questions in the future. How to cultivate junior students' problem-solving ability? First of all, help students to clarify the steps and requirements for solving application problems. I ask students to adhere to the five steps of "reading, finding, thinking, calculating and answering" every time they do an application problem. That is, first, read the questions accurately three times; Second, we must find out the conditions and problems; Third, we must think about the algorithm; Fourth, the calculation should be correct; Fifth, answer. In order to make students form habits, as long as I talk about application problems in class, I will stick to the five-step approach, demonstrate to students and influence them with my own actions.
