Nie Xiaoyuan, junior high school in Wangji Town, Xinye County, "intellectual education is not good for defective products, and moral education is not good for dangerous goods." It tells us that our society needs not only knowledge-based talents, but also outstanding talents with both ability and political integrity. At the same time, it also clearly points out the direction for our mathematics education, that is, infiltrating moral education into teaching. Classroom is the main channel for students to receive moral education. How to realize knowledge imparting, intelligence training and ideological and moral education in math class at the same time requires efforts in infiltration, which can be carried out from the following aspects. 1. Understand history and inspire patriotic enthusiasm. Patriotism education is one of the main tasks of school moral education. Proper use of historical knowledge in mathematics teaching will play a better educational role. By guiding students to read Pi, Nine Chapters Arithmetic, the optimization method of Chinese popularization, Chen Jingrun's Chen Theorem and the great achievements of Chinese-American scientists, we can not only stimulate students' patriotism and national pride, but also stimulate their enterprising spirit. Second, cultivate collectivism by using mathematical aesthetic feeling. Mathematics is not a boring subject, but actually contains many aesthetic factors. The characteristics of mathematical beauty are harmony, symmetry, order and unity. For example, collectivism can be infiltrated into this knowledge point when teaching circles. A circle is made up of countless points, just like a harmonious and beautiful family. Every family member has his own position and role, and also abides by collective discipline, which can enlighten students. You are like isolated points on a circle, and the class group is like a circle. The collective image and honor are inseparable from your efforts. If individuals don't abide by the collective discipline, they will be like a point that is not on the circle, drifting away from the collective and not getting the warmth of the collective. In this way, collectivism education will naturally penetrate students' hearts with vivid language. 3. It is one of the basic characteristics of mathematics to guide mathematics practice and cultivate the habit of paying attention to society. Strengthening the application and practice of mathematics can not only cultivate students' application consciousness and ability, but also cultivate students' good habit of paying attention to society. For example, when teaching the wide application of triangle knowledge in all aspects, it can inspire students that triangles are stable and can solve many problems in daily life. Only by combining mathematical knowledge with practical application can its use value be realized. In addition, in order to deepen students' understanding of knowledge and improve their ability to solve practical problems, teachers can give students some homework, or suggest students to observe and understand the application of mathematical knowledge in all aspects, guide students to actively participate in mathematical practice, and cultivate their habit of paying attention to society. Fourth, teachers set an example. The influence of teachers on moral education is not only the imparting of knowledge, but also the teachers' own thoughts, words and deeds, temperament, personality and moral cultivation. Therefore, mathematics teaching not only requires teachers to scientifically organize and optimize the teaching process, but also requires teachers to establish the idea of "learning to be an official" and to be a "silent teacher" with their noble personality charm; Teachers should pay attention to dignified manners, civilized language, seeking truth from facts, and have the heart of fraternity, selflessness and tolerance to influence, educate and influence students. In a word, it is an important subject to infiltrate ideological and moral education in mathematics teaching. In the practice of this topic, we must use flexible methods to organically combine moral education factors in the teaching of the content of the topic.
