Teaching content: Sujiao version of the fourth grade textbook 89 ~ 90 pages. Teaching Objectives: 1. To enable students to solve the practical problems in the process of learning to draw the schematic method of information, can draw on the schematic diagram to analyze the quantitative relationship between the problem-solving ideas. 2. To enable students to reflect on the process of solving practical problems, feel the value of using the method of drawing the schematic information, experience drawing information is a common solution to the problem. 3. To enable students to further accumulate experience in solving problems, strengthen the strategic awareness of problem solving, access to the successful experience of solving problems, and enhance the self-confidence to learn mathematics.
