【Teaching content】 Sujiao version of the fourth grade volumes 48 ~ 49 pages. Teaching Objectives 1. To enable students to initially understand the strategy of drawing, can draw lines to represent the conditions and problems of practical problems, learn to use quantitative analysis of quantitative relationships, explain the problem-solving ideas, and the correct formula. 2. Make the students draw line drawings to express the questions, analyze the process of quantity relations, understand the role of drawing, cultivate the thinking ability of using geometric intuition, judgment, reasoning and so on, and improve the ability to analyze the relationship between quantity and problem. 3. To enable students to take the initiative to explore problem solving, to obtain the feeling of success; further flu
