Teaching content: The Sujiao version of “compulsory education textbook mathematics” second grade volumes of the next 84 ~ 85 Example 1, “try ” and “think do ” 1 to 5 questions, practice nine 3 questions. Teaching Objectives: 1. To enable students to abstract the corner from the real situation of the process, to understand the composition of the corner and the name of each part, that angle is the size of the plane can be identified in the figure of the corner, can correctly point out the surface of the object The corner. 2. To enable students to further understand the close relationship between mathematics and life in the process of recognizing the angle, enhance hands-on
