Combining the characteristics of mathematics subject is the requirement of the new curriculum standard of primary school mathematics, and it is also an important task that primary school mathematics must complete under the new curriculum standard. It can avoid the bad influence of "exam-oriented education" which values intellectual education over moral education. Therefore, the contents of learning purpose education, study habit education and dialectical enlightenment education in moral education run through mathematics teaching, and moral education can improve students' ideological quality and promote their healthy development. I mainly infiltrate this experimental textbook from the following aspects:

First, combine the richness of mathematics textbooks to educate students to love the motherland and science.

According to the ideological education factors, illustrations, mathematical knowledge and rich ideological content contained in some numerical data in mathematics textbooks, students are educated to love the motherland and socialism. For example, there are pictures of large-scale electronic computers, solar cookers, the first artificial earth satellite launched by China, Nanjing Yangtze River Bridge and so on in primary school mathematics textbooks, and these pictures are generally concrete, vivid and convincing in combination with practical problems. Through the vivid explanation of these contents, students can feel the greatness of the motherland and the superiority of socialism, and be educated to love the motherland and socialism.

Second, combine the extensive application of mathematics in daily life and production construction, and educate students for the purpose of learning.

Studying for the motherland and the people is the external motivation for students to study hard. However, judging from the age characteristics and cognitive rules of primary school students, such a great truth tells them that the effect is not good. Therefore, teachers can educate students on the purpose of learning according to the fact that all activities such as food, clothing, housing and transportation are inseparable from mathematics in real life, and can also make use of the wide application of mathematics. Carry out basic knowledge education in close connection with practice, so that students can realize the practical significance of learning mathematics. For example, when learning to calculate, design a trading situation to introduce it. When students are found to make mistakes in calculation, explaining the mistakes to students will bring huge losses to production and work; When learning the understanding of time units, first explain the importance of time to students. For example, for a strategist, time is victory, for an educator, time is knowledge, for a medical scientist, time is life, for a farmer, time is food and so on. Let students know that time has its own importance to all kinds of people, and educate students to learn to cherish time to study. For another example, in the teaching of practical mathematics, the selected subjects are also combined with students' real life as much as possible, such as doing good deeds, greening and planting trees, saving water and electricity, protecting rare wild animals, and actively exercising. In this way, the knowledge learned is related to real life, industrial and agricultural production and the construction of the motherland. Let students achieve something in learning and become interested in learning useful things, so as to sprout the motivation to study for the prosperity of the motherland and the great rejuvenation of the nation and stimulate the enthusiasm to learn and use mathematics well.

Third, combine the routine of mathematics teaching and cultivate good habits.

Cultivating good habits is also an important part of students' ideological and moral education. Therefore, students should be strictly required in teaching, seize every opportunity, train repeatedly and cultivate good study habits.

1, pay attention to cultivate students' habit of listening attentively, which is an important prerequisite for students to understand knowledge. In the classroom, students are required to concentrate, cultivate self-control ability, consciously restrain their behavior, be free from external interference, be absent-minded, do not make small moves, listen carefully, actively explore and express their opinions boldly.

2. The habit of doing homework carefully. In the process of homework, students must be strictly trained in a serious and responsible learning attitude, writing neatly and regularly, drawing in line with requirements, examining questions carefully and comprehensively, calculating patiently and meticulously, and consciously form the habit of checking and calculating.

3. Pay attention to cultivating students' learning spirit of facing up to and overcoming difficulties. When students encounter difficulties in their study, they are encouraged to reconsider the problem and guide them to analyze it from different angles, so as to enhance their sense of success and self-confidence, and cultivate the spirit of independent thinking and dare to challenge difficulties.

Fourthly, the moral education infiltration measures of this experimental teaching material.

Mathematics learning can not only enable students to acquire the necessary knowledge and ability to participate in social life, but also effectively improve students' logical reasoning ability, thus laying the foundation for developing higher quality. Therefore, cultivating students' good mathematical ability is one of the important goals of mathematics teaching. One of the general ideas of this experimental textbook is to systematically and step by step infiltrate mathematical thinking methods, and try to present important mathematical thinking methods through simple forms and vivid and interesting examples that students can understand. Accordingly, in the "Mathematics Wide Angle" unit of this experimental textbook, the teaching of simple set thought and equivalent substitution thought is arranged. These mathematical thinking methods are not only widely used, but also the basis for further learning mathematics in the future. For example, set thinking is the most basic idea in mathematics, and students begin to use set thinking method when they start learning mathematics. Equivalent substitution is the basis of algebraic thinking method. At the same time, the introduction of these mathematical ideas provides good materials for cultivating students' logical thinking ability. Through observation, operation, experiment, guessing, reasoning and communication, the textbook enables students to feel the wonder and function of mathematical thinking methods, be trained by mathematical thinking, and gradually form an orderly and rigorous thinking consciousness, and at the same time make them gradually form an interest and desire to explore mathematical problems, discover and appreciate the beauty of mathematics.
