本节课是北师大版数学七年级下册第四章探索三角形全等的第三节第三课时。类比三角形两角一边的关系,探究两边一角在一个三角形中的位置关系,从而在不同的条件下得到三角形全等的又一方法“边角边”。与前面几节的学习形成一个严谨的课堂结构。
二、教学目标
1、掌握并会运用三角形全等的条件“边角边”(重点);
2、 在探索三角形全等的过程中体会类比思想,分类讨论思想,从一般到特殊再到一般的数学思想;
3、能进行有条理的思考和简单的推导。 (难点)。
三、学情分析
学生在掌握了说明两三角形全等至少需要三个条件及前面两节对边边边、角边角,角角边的探索思路的基础上,本节内容思路比较清晰。因此,本节主要通过学生自己动手操作、对比发现并总结,得到结论,最后通过一学一练的模式进行巩固应用。
四、教学方法与手段
整节课堂以学生为主,独立动手操作,做出满足条件的两个三角形,将两个三角形叠合在一起后,得出三角形全等的又一方法,最后,将练习题与知识点对应起来,进行巩固练习,层层递进,让学生成为探究,引领课堂的主人。

本节课是北师大版数学七年级下册第四章探索三角形全等的第三节第三课时。类比三角形两角一边的关系,探究两边一角在一个三角形中的位置关系,从而在不同的条件下得到三角形全等的又一方法“边角边”。与前面几节的学习形成一个严谨的课堂结构。
二、教学目标
1、掌握并会运用三角形全等的条件“边角边”(重点);
2、 在探索三角形全等的过程中体会类比思想,分类讨论思想,从一般到特殊再到一般的数学思想;
3、能进行有条理的思考和简单的推导。 (难点)。
三、学情分析
学生在掌握了说明两三角形全等至少需要三个条件及前面两节对边边边、角边角,角角边的探索思路的基础上,本节内容思路比较清晰。因此,本节主要通过学生自己动手操作、对比发现并总结,得到结论,最后通过一学一练的模式进行巩固应用。
四、教学方法与手段
整节课堂以学生为主,独立动手操作,做出满足条件的两个三角形,将两个三角形叠合在一起后,得出三角形全等的又一方法,最后,将练习题与知识点对应起来,进行巩固练习,层层递进,让学生成为探究,引领课堂的主人。
