The subject and the teaching content teaching the process of the process of the process of the process of learning the attitude of learning to learn the knowledge skills The recognition and surface area of the cylinder class 4 1. To make students understand the characteristics of the cylinder, to understand the plan of the cylinder; Understand the unfolding of the cylinder side. 2. Understand the meaning of the cylinder side area and the surface area of the cylinder, and master the calculation method of the cylinder side area and the surface area. 3. According to the relationship between the surface area of the cylinder and the side area, students should learn to solve simple practical problems with the knowledge they have learned. Exchange students through practical operation, observation, thrust calculation process, understand the meaning of circular column lateral area and cylindrical surface, master the computing method of cylindrical lateral area and surface area Cultivate students space conception, stimulate students interest in learning mathematics Teaching process design preset teaching path Review: show all kinds of graphic graphics, let students point out the calculating method of each area. The paper focuses on the method of solving the surface product of the circle and the solving method of the circumference of the circle. New lesson 1. The teacher in the new class takes a rectangular shape and a cube shape, and asks: what shape is the object in my hand? What are their characteristics? Guide students to review some features of cuboid and positive square. What are the characteristics of these objects?
