Teaching content: PEP Edition “compulsory education textbook · Mathematics” fourth grade on the first page 105 cases. Teaching Objectives: 1. Through simple examples to enable students to initially understand the application of optimization thinking in solving problems, to form a search for the optimal solution to the problem awareness, and try to find the best solution to the problem. 2. Through the observation, operation, comparison, discussion, thinking and other activities to find the law, to develop students ability to solve practical problems, abstract thinking ability and spirit of scientific inquiry. 3. Exploring activities enables students to experience the fun of exploration and cooperation, fully experience the tremendous impact that mathematical thinking and methods have on real life, and cultivate students’ good habits of rational arrangement, saving time and improving efficiency. Teaching focus: looking for strategies and solutions to problems
