符号化思想是数学中的重要思想方法之一。数学作为以符号与逻辑为主体的学科,存在抽象性特征,容易造成学生的理解障碍。为此,笔者结合自己的实践,简要谈谈小学数学教学中如何渗透符号化思想。一、逐步渗透中认识符号符号是小学《数学》教材内容的重要组成部分,依据符号的作用大概能够将符号分为以下几种类型:①个体符号,主要作用是表示数或者数量,例如:1、2、3、4、5…a、b、c、d…,π和x
Symbolic thinking is one of the important ways of thinking in mathematics. Mathematics, as the subject with symbols and logic as the main body, has abstract characteristics, which easily lead to students’ understanding of obstacles. To this end, the author combined his own practice, briefly talk about how to infiltrate the symbolic thinking in elementary mathematics teaching. First, the gradual infiltration of symbols in the understanding of primary school “mathematics” teaching material content is an important part of the symbol based on the role of symbols can be roughly divided into the following types: ① individual symbols, the main function is to represent the number or quantity, for example: 1 , 2,3,4,5 ... a, b, c, d ..., π and x
