Teaching Content: Textbook 105-106 Example 1 and practice a practice, exercise sixteen questions 1-3. Teaching Objectives: 1. To enable students to learn how to use transformation strategies to analyze problems, and to determine the specific conversion methods according to the characteristics of the problems so as to effectively solve the problems. 2. To enable students to further accumulate experience in problem solving, enhance the sense of strategy to solve the problem, to obtain a successful experience to solve the problem. Students actively participate in mathematics activities, be willing to exchange strategies with peers to solve problems, and can take the initiative to overcome the difficulties encountered in the process of problem solving, improve students’ self-confidence in mathematics.
