First, teachers' accurate and standardized mathematical language has a subtle influence on students.

Teachers' words and deeds have a subtle influence on students, so we should cultivate students' mathematical language expression ability, standardize teachers' language and set an example for students. Mathematics teachers should accurately describe concepts, laws and terms, and don't let students have doubts and misunderstandings. Second, let students train their mathematical language expression ability in oral expression.

In order to train all students' mathematical language, teachers can flexibly use the training mode of "deskmate communication, group discussion, classroom evaluation and student summary", and implement the teaching idea of "language training as the main line and thinking training as the main body" in classroom teaching, so that students at different levels can have something to say, stimulate students' enthusiasm for speaking and improve their speaking ability in positive evaluation.

(1) Pay attention to let students tell the essence in concept teaching.

Speaking training in concept teaching is a bridge from intuitive knowledge to rational knowledge. Therefore, in concept teaching, teachers should pay attention to let students describe the essence of concepts, so that students can not only say specific contents such as definitions, theorems, formulas, laws and properties in their own language, but also say the key words of concepts. For approximate concepts, ask students to tell their similarities, internal relations and confusion.

(2) Pay attention to let students tell the reasons in calculation teaching.

In computing teaching, strengthening computing teaching and paying attention to the process of speaking can not only help students consolidate the computing methods they have learned, but also cultivate their thinking and expression skills. In computing teaching, teachers should let students talk about arithmetic and operation order, and introduce their own algorithms and the reasons for optimization. At the same time, let students tell the reasons for the calculation errors and their own opinions, so that students' observation, attention and thinking ability can also develop simultaneously.

(3) Pay attention to let students speak freely in the teaching of applied problems.

In the teaching of practical problems, let students analyze and reason methodically and reasonably, express their ideas through oral problem-solving ideas, and fill in quantitative relations. And carry out mathematical language training. In class, what students say can not only arouse students' learning enthusiasm, but also enable teachers to get feedback information in time and understand students' mastery of knowledge.

(4) Pay attention to let students tell their own characteristics in geometry teaching.

The teaching of geometric shapes can cultivate students' spatial concept and develop their oral expression ability. Therefore, in the teaching of geometric figures, through discussion and communication, let students talk about their characteristics and their connection with life; We also attach importance to the participation of students in the process of formula derivation. Through practical operation and oral formula derivation, students can combine the acquisition of knowledge with the development of mathematical language, stimulate students' desire to explore space, seize the opportunity and develop their oral ability.

Fourthly, enrich the mathematical language in students' mathematical reading.

Fifth, in students' "writing", strengthen the mathematical language.
