As we all know, the main task of primary and secondary school students is not only to learn scientific and cultural knowledge, but also to learn the truth of being a man. Our education must serve socialist modernization, and the students trained must have both ability and political integrity to meet the needs of socialist construction and the rejuvenation of the Chinese nation. Therefore, in the usual education and teaching activities, moral education should be put in the first place and infiltrated into all disciplines and activities. Modern curriculum theory also emphasizes the connection and infiltration between disciplines more and more, so as to enhance the comprehensive application of all kinds of knowledge. As a teacher, in education and teaching, we should not only impart new knowledge, but more importantly, pay attention to the cultivation of students' moral quality while imparting knowledge, and infiltrate students' moral behavior education into various disciplines and activities. Students spend most of their time in the classroom, and classroom teaching has become the main channel and position for ideological and moral education for students. Below, the author talks about some superficial understanding on "how to infiltrate ideological and moral education in primary school mathematics classroom teaching"

1. Be good at excavating the inner beauty in mathematics courses and cultivating students' beautiful hearts and noble sentiments. In primary school mathematics textbooks, there are many contents that can be used as carriers of ideological and moral education. For example, the relationship between spatial form and quantity provides mathematics with extremely rich content, which makes it full of beautiful emotions, feelings, expressions and creations. Such as symmetry, unity, simplicity, singularity, curve and so on. After teaching the knowledge of ratio and proportion, I introduced the famous knowledge of "golden section" to students, thus revealing an aesthetic relationship between line segments and proportion, and then let students look for things constructed according to the golden section in their daily lives. For example, famous Chinese and foreign buildings, drawstrings for curtains, belts for girls' skirts, etc. Let students enjoy beauty from it. I also often let students discover and feel some life wisdom from mathematical knowledge and real life with a philosophical eye, and cultivate students' positive attitude towards life. A great man once made such a metaphor: "A person's actual value is like a molecule, and his evaluation of himself is like a denominator. The larger the denominator, the smaller the score. " It is the ultimate goal of our mathematics teaching to let students explain such profound principles of being a man from such simple mathematical knowledge and complex society. In my opinion, only by being good at digging up teaching materials, infiltrating ideological and moral education in time, and letting students study mathematics happily and appreciate the beauty of mathematics in a beautiful situation can we realize the true meaning of life and cultivate students' noble sentiments.

Second, combine the application of mathematical knowledge to promote the cultivation of students' excellent moral character. In primary school mathematics teaching, especially in senior grades, teachers should closely combine the teaching of applied problems, and help students gradually master the basic methods of "analyzing the problem structure, processing data, grasping the main contradiction, conducting abstract reasoning, establishing quantitative relations, rationally reasoning and solving, and testing and correcting the results" through the research and solution of practical problems, so as to cultivate students' adaptability in the fierce changes and competition in the future. Combining the characteristics of correctness of mathematical calculation, conciseness of solution and harmony of graphic structure, we can cultivate students' tenacious learning perseverance, scientific attitude of seeking truth from facts and healthy aesthetic taste. At the same time, combined with the knowledge of applied mathematics, we can solve the mathematical problems of saving raw materials, saving time, reducing costs and improving efficiency in production and life, help students develop diligent, simple, frugal, fast and efficient behavior habits from childhood, and lay a good foundation for becoming a socialist modernization builder with high sense of responsibility and excellent moral quality in the future.

In short, in the classroom teaching activities of primary school mathematics, teachers should fully tap the infiltration point of ideological and moral education in primary school mathematics textbooks according to the teaching characteristics of mathematics subjects and the reality, always pay attention to students' ideological reality, teach students in accordance with their aptitude, and carry out good moral education. At the same time, teachers should pay attention to being a teacher, paying attention to the cultivation of teachers' morality, paying attention to professional image and language, always influencing and educating students with their own words and deeds, so that students can consciously form good moral consciousness and behavior habits. Then, why can't our educational goals be achieved? The ideological and moral education in our primary school mathematics classroom teaching will certainly receive satisfactory results.
