一、教学目标1.能根据相关条件,求出存在点的坐标。2.通过习题的拓广与探索,使学生在数学思维上得到迁移和发散。3.在“解决问题——分析问题——发现问题——提出问题”的过程中,使学生在数学思想方法方面得到进一步的体验和积累。二、教学重难点教学重点:对于存在性问题的探索。教学难点:数学思想方法的形成与积累。
First, the teaching objectives 1. According to the relevant conditions, find the coordinates of the existence of points. Through the extension and exploration of exercises, students can be migrated and diverged in mathematical thinking. 3. In the process of “solving problems - analyzing problems - finding problems - asking questions”, students are further experienced and accumulated in mathematical thinking and methods. Second, teaching heavy and difficult teaching focus: exploration of the existence of the problem. Teaching Difficulties: The Formation and Accumulation of Mathematical Thinking Methods.
