The types of mathematics classes include concept classes for teaching mathematical concepts, method classes for teaching mathematical methods, review classes for units or chapters, lectures and evaluation classes for test paper exercises. As far as my teaching experience is concerned, I think the most difficult course is the math concept course, which is urgently needed to be good, because math concept teaching is the first process in math teaching, and whether students understand and grasp the concept accurately will directly affect the effect of subsequent math learning. Therefore, I think that the expression of mathematical concepts should use refined language to accurately reflect the essential characteristics of concepts. The teaching design of a good mathematical concept class needs to be considered: what stages can concept teaching be generally divided into? What problems should be solved in each stage? The key to the teaching design of mathematical concept course lies in scientifically and artistically handling the contents of teaching materials and stimulating students' strong thirst for knowledge. Starting with the life experience that students are familiar with and personally feel, we should make it mathematical. There should be four stages: concept introduction, concept discrimination, concept deepening and concept consolidation. On the basis of teaching materials, students can transfer knowledge and actively establish an understanding of new concepts. In the teaching of mathematical concepts in primary schools, some concepts can be obtained through direct contact with real life. But there are also many mathematical concepts that cannot be obtained in this way. They can only be defined by language. Students need to understand the connotation and extension of these languages in order to get their exact meaning. Consider the whole chapter, let the students see the concept first, and lay the foundation for his future study. Students can deepen their understanding of concepts by giving counterexamples. When necessary, the analytical concept needs to be scrutinized repeatedly. Only in this way can we highlight the essence of the concept. The introduction of the concept of \x0d focuses on attracting students' attention, stimulating students' interest, embodying the essence of the concept and containing the thinking method of concept occurrence, so as to achieve sound production. There are many ways to introduce, and the common ones are as follows: first, mathematical stories introduce mathematical concepts; Second, introduce concepts through students' existing knowledge and experience; Thirdly, hands-on operation introduces mathematical concepts; Fourthly, introduce mathematical concepts through practical problems. \x0d Conceptual analysis We should also be good at reverse analysis, illustrate by counterexamples, and carry out conceptual analysis. When necessary, we will properly use multimedia animation to solve abstract problems, concretize abstract problems through multimedia, and let students have a perceptual understanding. Understanding concepts, especially some important concepts, often cannot be solved in one class. We need to put it into the whole math course to understand some concepts. To what extent have I mastered this concept in this class and where can I expand these concepts in the future? We can talk about topics, but the purpose of our topic is to improve students' literacy, improve their understanding of certain concepts and deepen their understanding. Concept teaching not only appears in concept class, but also their understanding of concepts. It should be a starting point that we should pay attention to anytime and anywhere in other courses. Therefore, as a concept course, it not only emphasizes the explanation of concepts, but also penetrates into other courses, giving full play to the maximum efficiency of concept courses \x0d Mathematics concept is the soul of every content, and only by explaining it well can we make good use of it. In order to make students master it well, I would like to talk about the following points: \x0d Mathematics concept teaching is generally divided into three parts: introduction, analysis and application. The introduction of the concept of \x0d must pay attention to attracting students' attention and stimulating their interest in learning. It is mentioned in the new curriculum standard that the introduction of mathematical concepts should be situational, natural and not imposed on others. In the setting of the situation, it must conform to the students' cognitive rules and be close to life. Do not pay attention to form. \x0d correctly and fully provided various variants of the concept in the analysis process. Proper application of counterexamples and listing some specious and error-prone objects for students to discriminate are effective means to promote students to understand the essence of concepts and determine the extension of concepts. X0d gives students the opportunity to understand concepts from different angles in the process of systematically learning concepts, which is not only conducive to developing the structural function of knowledge and making concepts have growth vitality, but also conducive to the acquisition, maintenance and application of knowledge, which is of special significance to developing students' generalization ability. Carefully design exercises, strengthen the connection between concepts in application, consolidate the concept network and deepen the understanding of concepts.
