I. Examination training

Examining questions is to understand the meaning, known conditions and problems in the questions. Careful examination of questions is an important prerequisite for students to solve problems correctly, but it is easy to be ignored, which leads to mistakes. According to the characteristics of application problems, it is the key to correctly solve problems to quickly and accurately determine the thinking direction and deeply understand the quantitative relationship. On the basis of comprehensible reading, carefully examine the questions and determine the thinking direction and method of solving problems. Finally, through careful reading, compare the solution formula and answer with the question to see if it meets the meaning of the question. Strengthen the training of examining questions and improve the correct rate of solving problems.

Second, line drawing training

Line drawing training is aimed at the characteristics of primary school students' strong concrete thinking ability and weak abstract thinking ability, and guides them to vividly reveal the quantitative relationship in the topic, understand the meaning of the topic and find out the method of solving the problem with the help of line drawing. For slightly complicated application problems, the concrete and intuitive line segment diagram is an effective way to help students understand the meaning of the problem.

Third, training with multiple solutions to one question

In the training of multiple solutions to one problem, students can be inspired and guided to analyze and solve application problems from different angles, different ideas, different methods and different operation processes. This can not only consolidate the knowledge students have learned, but also expand the thinking of solving problems, enhance the flexibility and originality of thinking and develop their intellectual potential.

Fourth, supplement questions and conditions, and train self-made application questions.

Analysis and synthesis are two commonly used methods in the teaching of application problems in primary schools, and they are the focus of application problems teaching. The effective ways to cultivate students' ability to solve problems by analytical method or comprehensive method are to supplement problems and conditions, and to compile and apply training. Supplementary questions and conditions, as well as self-made application questions, enable students to master the structure and quantitative relationship of application questions from different angles by changing the known conditions or problems in the questions, thus improving students' analytical and comprehensive ability.
