1 Teaching Objectives (1) Through the review of the method and nature of the square, let students understand the general methods of identifying, exploring, and applying squares to solve problems, and realize the methods of active experiment and exploration of new knowledge. (2) cultivate students’ ability of observation and discovery, the ability of describing the geometric language and the basic model of using a total of vertices and squares to raise questions, analyze problems and solve problems. (3) In organizing the process of guiding students to explore, students are encouraged to develop independently and develop the habit of cooperation and exchange among students.
