数学思想是数学基础知识及基本技能的本质体现,是数学知识的升华和结晶.虽然教科书上没有专门的章节介绍,但它却一直伴随着我们的整个学习过程,随着新课程的不断实施,近几年来的中考命题也在不断地加强对数学思想方法的考查力度.下面仅以一些小题目中出现的思想方法为例予以说明,供同学们在学习过程中参考.一、整体思想例1如图1,在直线l上依次摆放着七个正方形,已知斜放置的三个正方形的面积分别为1、2、3,正放置
Mathematical thinking is the essence of mathematics basic knowledge and basic skills. It is the sublimation and crystallization of mathematics knowledge. Although there are no specific chapters in textbooks, it has always been accompanied by our entire learning process, with the continuous implementation of new courses. In recent years, the examination proposition has also been continuously strengthening the examination of mathematical thinking methods. The following only some of the ideas appearing in small topics as an example to illustrate for the students in the learning process for reference. First, the overall thinking example 1 As shown in Fig. 1, seven squares are placed in sequence on the straight line l. The areas of the three squares known to be placed obliquely are 1, 2, and 3, respectively.
