As far as the content of primary school mathematics textbooks is concerned, we can generally explore or set the "breakthrough point" of moral education from the following five aspects: meaning and data; The causes of concepts, rules, laws and formulas; Inserts, illustrations and statistical charts; History of mathematics and stories of mathematicians. For example, when teaching abacus, the teacher introduced abacus to the students as a great invention of the working people in our country. Because it is easy to learn and operate, it is popular not only in China, but also in East Asia and European countries. Combined with the teaching of decimal notation, this paper introduces that China started to use this advanced notation in Shang Dynasty before BC, which is the first country in the world to use this notation. Teachers' brief introduction can arouse students' strong sense of national pride, thus achieving the purpose of patriotism education for students.

2. Combined with the teaching process, timely infiltration

Teachers' ideological and moral education through the penetration point is not limited to a word, a sentence, a question, an example, a picture or a table, but also a teaching link and a teaching process. For example, when teaching "weight unit", add "If everyone saves one grain of rice, 65.438+0.2 billion people in the country can save 65.438+0.2 billion grains of rice, with a weight of 2.97 million grams. How many kilograms? " After the students worked out the result of 2970 kilograms, the teacher immediately told the students that the rice could feed about 2 1 person for a month. Educate students to save a grain of rice and a drop of water, and form a good habit of thrift.
