谈谈初中数学教材中的分类思想

Discussion on Classification Thought in Middle School Mathematics Teaching Material

分类思想是数学思想方法中的一种。数学概念、法则、公式等知识都明显地写在教材中，是有“形”的，而数学分类思想却隐含在数学知识体系中，是无“形”的，并且不成体系地散见于教材各章节中。我们教学时，应根据不同的教学内容。教会学生运用分类思想去解决各种问题。

Classification is one of mathematical methods. There is a ＂form＂ for the knowledge of mathematical concept, principle, formula etc obviously written in teaching material. However, there is no ＂form＂ for classification method contained in the mathematics knowledge system and appeared in textbook chapters with no system. According to different content, teach classification method for students to solve various problems.
