Language is a tool for communication between people, it facilitates the expression of our human thoughts. Because every subject has its own way of language expression at school, then we need to use the language in our mathematics when we study mathematics. That requires teachers to set a good example in the teaching process and always pay attention to their words and deeds. Teachers should regulate the use of mathematical language in the course of class, let students perceive its existence, and enable students to form their language in a multi-listening atmosphere. The new curriculum reform focuses on the comprehensive development of students, and points out in the new language curriculum that the knowledge learned in the mathematics curriculum provides thinking, language and methods for other disciplines.
