【Abstract】 In the long-term mathematics teaching, it is found that students' classroom learning effect is very good, but the quality of independent learning is not high. Students with poor mathematics reading ability find it difficult to understand various learning materials and encounter obstacles in learning. Therefore, improving mathematics reading ability helps to promote students' math learning. This article introduces the understanding of mathematics reading from the following aspects: one is the role of mathematics reading in the learning process; the second is the use of various mathematics languages in textbooks; the third is the training of commonly used mathematics reading methods. To enable students to have good mathematics reading skills, they must master the reading methods and require hard training. The improvement of reading ability will help students' lifelong learning and development.

一、数学阅读在学习过程中的作用
具备一定的数学阅读能力是学生数学学习、理解、运用科学知识和技能等方面的基础。提高数学阅读能力既可以让学生的数学语言系统更丰富完善,还能提高他们对数学知识的理解和表达。通过阅读数学书中的定理、概念、规律,才能引领学生分析定义、定理或公式的内涵和外延,使数学教科书的作用得以充分发挥,有助于学生个别化学习。
二、数学语言的特点与作用
数学语言根据其表述形式可以划分成文字、符号和图形三种语言形式。文字语言具有强大的表达功能,有很强的精练性、严密性,它适合叙述数学的各类知识。将文字语言符号化就是符号语言,数学符号具有精准、清晰和减缩等特点。符号语言往往是学生阅读过程中最大的障碍,这是因为它高度的集约性、抽象性。……
