【Content】 West division version of the fifth grade on the fifth unit parallelogram area (textbook is 79 ~ 80). Teaching Objectives 1. To enable students to explore, understand and grasp the area of parallelogram formula, will calculate the area of parallelograms. 2. Through the operation, observation, comparison and other activities, primary understanding of the transformation method, training students to observe, analyze, summarize, and derive their ability to develop the concept of space students. 3. To guide students to understand the initial ideas and methods of transformation, develop students’ thinking ability and ability to solve simple practical problems. Teaching heavy difficult teaching focus: to explore and derive the formula of parallelogram area, and can
