1. In the process of solving simple practical problems, students can initially understand the function of drawing lists to organize relevant information, and feel that drawing lists are a strategy to solve problems. I will sort out the information provided by simple practical problems by drawing schematic diagrams or lists, and analyze the quantitative relationship through the process of drawing schematic diagrams or lists to find effective methods to solve problems.

2. Enable students to further accumulate experience in solving problems, enhance their awareness of problem-solving strategies, gain successful experience in solving problems, and improve their self-confidence in learning mathematics well. Therefore, a deep understanding of different methods can test each other and improve the learning level.
