Briefly describe the main teaching strategies of problem solving;

A: (1) Students should be encouraged to think and solve problems in different ways from different angles.

(2) When solving problems, arrange students to cooperate in groups as much as possible, on the one hand, cultivate students to learn to cooperate and communicate with others, on the other hand, they can be inspired by discussions among students, so that students can consciously seek diversification and optimization of problem-solving strategies.

(3) Problem-solving strategies are very important for students, and it is also very important to reflect on the results in time. In the process of learning, students should often be asked such questions: What did you think and how did you do it just now? What will happen if ...? What's the matter? What would you do? Which method do you think is better? Use these questions to attract students' attention and let students gradually develop the awareness of evaluation and the habit of reflection.

Mathematics is a subject closely related to the reality of life, and students should study independently in the real situation closely related to life. More importantly, use knowledge. Through some activities, students can compare, observe and analyze, and then summarize and discuss the laws of things, thus improving students' problem-solving ability.

In primary school mathematics teaching, problem-solving strategies are not fixed, and when solving the same problem, they are not limited to the application of one strategy. Using strategies to solve practical problems requires a holistic concept. In teaching, teachers should make use of the situation to make students feel that different problems can be solved by different strategies through comparison, and strive to optimize the combination of methods and choose them properly.
