Teaching content: PEP “compulsory education textbooks? Math” fifth grade on the first 74 ~ 75 pages. Teaching Objectives: 1. Through the drawing to understand the information, find the relationship between the information and the problem, correct column equations to solve the problem. With the combination of number and shape, through active attempts, collective communication to improve students’ understanding of the problem, analyze the problem and the ability to solve the problem. 3. Preliminary experience of the characteristics of the equation in solving practical problems and their superiority. Teaching focus: find the same amount of relations, lists the equation. Difficulties in teaching: Analysis of information to find the same amount of relations. Teaching preparation: courseware, practice paper. Teaching process: First, create the situation, leads to the problem division: autumn, it is a good season to travel. (Courseware show pictures) Guess where is this?
