1. Let students practice their existing knowledge and experience. Managers will talk about the process of abstracting practical problems into formulas and equations, further understand the ideas and methods of equations, and enhance their awareness and ability to solve practical problems by enumerating equations;
2. In the process of solving equations and simple practical problems, further feel the thinking method and value of equations, develop abstract thinking and enhance the sense of symbols.
