《平行四边形及其性质》教学设计（Teaching design of parallelogram and its properties） Information worth having It comes from the accumulation of learning There must be a problem Also please criticize the correct! Teaching design of parallelogram and its properties 1. Learning objectives 1. Grasp the properties of parallelograms Simple reasoning and calculation can be made using the properties of parallelograms 2. The process of experiment - conjecture - proof Develop the students thinking level and good thinking quality 3. Experience mathematics and life Stimulate students interest in learning Ii. Key points and difficulties 1. Key points: the properties of parallelogram. 2. Difficulty: using the properties of the parallelogram to conduct the related argumentation and calculation. Teaching methods and means The mode of classroom activity of creative situation - bold conjecture - experimental inquiry and evaluation was adopted Efforts should be made to create a learning atmosphere of autonomy, cooperation and exploration Use multimedia to assist in teaching A vivid and intuitive reflection of the situation To make students have a pleasant mathematical experience in study Iv. Teaching process (1) before the class Use stories to import new lessons Show this picture Motivate the students to be motivated Try to find various ways to find the area of the parallelogram But there is no suitable solution The teacher took the opportunity to introduce the subject Clear learning task Create a lively and interesting situation here Strive to better stimulate students interest in learning (2) inquiry within the course 1. Explore one in class (explore the side-angle relationship of parallelogram) Observation and thinking: In the primary school Weve seen the parallelogram and its characteristics Consider and answer the following questions: (1) observe the following figures What kind of parallelograms do you see? Can you give an example of parallelogram used in life? (2) what is the position relation
