教学目标: 1.让学生在经历探索轴对称性质的过程中,进一步体验和感受轴对称和轴对称图形,发展学生的空间观念; 2.引导学生在探索、分析轴对称的基本性质的实践中,理解对应点所连的线段被对称轴垂直平分,对应线段相等,对应角相等; 3.通过动手操作、实践、观察、思考,让学生体验数学活动的实践性、探索性,积累活动经验,发展实践能力。在合作交流的过程中,学会与人合作,树立创新意识。
Teaching Objectives: 1. To allow students to experience and experience axial symmetry and axisymmetric graphs and develop students’ spatial concepts while experiencing the axisymmetric nature; 2. Guide students in the practice of exploring and analyzing the basic properties of axial symmetry. , Understand that the line segment connected to the corresponding point is divided vertically by the axis of symmetry. The corresponding line segment is equal and the corresponding angle is equal. 3. Through hands-on operation, practice, observation, and thinking, students can experience the practicality, exploratory nature of mathematics activities, and accumulate activity experience. Develop practical ability. In the process of cooperation and communication, learn to cooperate with people and establish a sense of innovation.
