While standardizing students' mathematical language, teachers should pay more attention to the standardization of language, so that students can form standardized mathematical language in imitation. Children's imitation ability produces appearance, which can be a preparation for future thinking. For primary school students, language expression ability is not perfect. But they are imitations. This requires that teachers' language in class should be used as a model and become the basis for standardizing students' language. Therefore, teachers' language should be accurate and demonstrative, and teachers must speak with standardized language, appropriate words and concise words. The concept statement should be accurate, standardized and logical, and the discussion of problem-solving ideas should be justified. Pay attention to the order. Improving students' mathematical language ability is not an overnight event, and the training of "speech" needs to run through daily mathematics classroom teaching. In teaching, teachers should strive to strengthen students' "speaking" training. Let students experience the process of daring to think and speak, being willing to think and speak, being able to speak and being good at thinking and speaking, let students express the calculation process, computational reasoning, problem-solving ideas and the thinking process of acquiring knowledge in accurate, concise, clear and coherent mathematical language, and let students practice their talents, courage, wisdom and skills through "speaking"; Let students "speak rationally, coherently and completely", and then let students "speak intelligently" and "speak brilliantly".

Mathematics learning activities are basically mathematical thinking activities, and mathematical language is a tool of mathematical thinking, so mastering mathematical language is one of the important foundations for carrying out mathematics learning activities smoothly and effectively. It is necessary to closely combine the cultivation of students' mathematical language with the study of mathematical knowledge as an important part of mathematical learning. Only in this way can students' thinking be better organized, logical and accurate.

Mathematical language is highly abstract, and mathematical reading requires strong logical thinking ability. Only by learning relevant mathematical terms and symbols and correctly analyzing logical relations according to mathematical principles can we truly understand books. At the same time, mathematics has its accuracy, every mathematical concept, symbol and term has its precise meaning, there are no ambiguous or ambiguous words, and the conclusion is obviously wrong. Therefore, math reading needs careful thinking, but also hard thinking. In order to really learn mathematics well, implement the goal of mathematics quality education and make mathematics no longer difficult to learn, I think we must attach importance to mathematics reading, which is actually a very simple truth-people who read more books have better oral expression ability and composition level than those who read less. At the same time, we can truly achieve the "double-qualified" teaching thought with students as the main body and teachers as the leading factor.

As a math teacher, language should be a role model for students. Because children are highly imitative, teachers' mathematical language directly affects students' mathematical language. Therefore, teachers' language strives to use words accurately, concisely, clearly, coherently and logically. This requires teachers to constantly improve their language literacy, and through the exemplary role of teachers' language, it will have a good influence on the formation of students' initial logical thinking ability. How can we improve the language expression ability of primary school students? The following forms can be taken to enable students to develop mathematics language.

1. Group discussion: Group discussion is a common way in class. Select team leader, recorder, etc. In each group. When there are difficulties in learning, students can be invited to discuss in groups, and representatives can communicate after the discussion. By doing so, every student has the opportunity to speak and listen to others. Have the opportunity to express their views in front of several people and the whole class. In order to express the opinions of the group, students think, listen and organize more actively, and use old and new knowledge flexibly, so that they are fully excited about active learning, and at the same time increase the classroom density and get twice the result with half the effort.

2. deskmate communication: deskmate communication is very convenient, and it is also a good way to let students express their opinions and cultivate their language ability in classroom teaching. Especially in the new teaching, students have mastered certain methods, which need to be summarized in time.

3. Let students summarize: Summary is an important part of classroom teaching. Summarization can improve students' comprehensive generalization ability and clearly recall the main points of this lesson. Although the expression ability of primary school students is limited, it can be correctly summarized as long as it is correctly guided. For example, after learning the comparison of decimals, I asked my classmates in the class summary: "What have you gained through this class?" After sorting out the memories, the students raised their hands to speak one after another, and even the students who are usually quiet and some underachievers are very active. Although some students are concise, they have grasped the key points of this lesson, which not only deepened their understanding of knowledge, but also developed their learning ability. Moreover, regular and purposeful classroom summary can improve students' logical thinking ability such as analysis, generalization and classification, and achieve the goal of intelligent progress and comprehensive education. Various forms of training, so that every student has the opportunity to speak, at the same time, students speak their own ideas, there will be a sense of pleasure, but also the need for self-expression and self-realization

4. Strengthen students' mathematical language in operation: Operation is a cooperative activity of students' hands and brains, and it is an effective means to cultivate and develop students' thinking. Language is the externalization of thinking and the material form of thinking. The internalization of knowledge and corresponding intellectual activities must be internalized with the process of language expression. Therefore, we should attach importance to students' hands-on operation in teaching. When guiding students to operate hands-on, we should pay more attention to let students describe the operation process in an orderly way with mathematical language, express the thinking process of acquiring knowledge, organically combine hands-on operation, brain understanding and verbal expression, promote the effective transformation of perception into internal intellectual activities, and achieve the purpose of deepening understanding knowledge. Thinking through hands-on operation, expressed in mathematical language, not only deepens the understanding of the meaning of fractions, but also tests students' mastery of new knowledge and develops students' logical thinking ability.

In a word, the cultivation of mathematical language is a long-term task in teaching. It can enable students to get opportunities for mathematical communication, develop students' mathematical thinking, cultivate students' initiative in learning, establish self-esteem and self-confidence in learning, and improve their listening and speaking ability.
