Abstract

Mathematical model is the starting point of students' problem-solving thinking, and cultivating students' model thinking is helpful to broaden their thinking and improve their ability to analyze and solve problems. Familiar with and master the application of the model, which can help students directly grasp the key of the problem, overcome the obstacles of problem solving, and shorten the problem solving time. Through the analysis of several typical mathematical models and example problems, help students understand and apply models, penetrate ideas, and develop core mathematical literacy.

Key words: Mathematical model; A line of three equal angles; General Feeding water to his horses; Why not return
