“图形的旋转”是人教版九年级《数学》上册第二十三章第一节的内容.一、教学目标1.知识与技能:理解图形旋转的性质,能按要求作出旋转后的图形.2.过程与方法:让学生在动手操作中,实现从直观到抽象,从感性认识到理性认识的转变,培养学生的观察能力、分析能力、空间想象能力、审美能力. “Graphic rotation” is the content of the first section of the twenty-third chapter of the 9th grade mathematics of the People’s Education Press. I. Teaching objectives 1. Knowledge and skills: Understanding the nature of the rotation of the graph, can be rotated as required Figure 2. Process and method: In the hands-on operation, students are allowed to change from intuition to abstraction, from perceptual knowledge to rational knowledge, and to cultivate students’ observation ability, analytical ability, spatial imagination ability and aesthetic ability.
