Teaching objective: 1. It can be recognized that simple patterns in life are obtained through axisymmetric or translational graphics. You can collage or design graphics in a square, and create your favorite patterns through axial symmetry, translation and other movements. 2. I will put the same patterns together, determine the basic graphics of the observation results according to the actual situation, and describe the movement of the graphics in my own language. 3. Through the process of observation, operation and cooperation and communication, the basic method of designing graphic movement patterns is obtained, and the students' spatial concept is developed in the process of imagining graphic movement. 4. In the process of appreciating beautiful patterns, further feel the extensive application of axisymmetry, translation and rotation in life, feel the beauty of mathematics and appreciate the value of mathematics. Target analysis: This is an activity class of "synthesis and practice". On the basis of the knowledge of axis symmetry, translation and rotation, students appreciate and create patterns through practical activities, describe the movement of graphics in their own language, gradually develop the concept of space, feel the beauty of mathematics in life, and cultivate innovative spirit and practical ability. Teaching emphasis: be able to use the knowledge of graphic movement to design patterns. Teaching difficulty: developing students' initial concept of space. Teaching preparation: courseware, scissors, glue sticks, handmade paper, etc.
