《义务教育课程标准》(2011年版)(以下简称“新课标”)明确指出:“分类是一种重要的数学思想.学习数学的过程中经常会遇到分类问题,如数的分类、图形的分类、代数式的分类、函数的分类等.在研究数学问题中,常常需要通过分类讨论解决问题,分类的过程就是对事物共性的抽象过程.”因此,教师在教学过程中要注意渗透分类讨论的思想.以下谈谈笔者在图形概念课教学中贯彻分类
Compulsory Education Curriculum Standard (2011 Edition) (hereinafter referred to as the “New Curriculum Standard”) clearly states: “Classification is an important mathematical thought .Mathematics learning process often encounter classification problems, such as the number of Classification, classification of graphics, classification of algebraic functions, classification of functions, etc. In the study of mathematical problems, it is often necessary to solve problems through classification and discussion, and the process of classification is the abstract process of the commonality of things. ”Therefore, teachers in the teaching process Pay attention to the idea of infiltration classification discussion. The following talk about the author in the classification of graphics concept teaching
