As math teachers, we often encounter such a situation. Some students are very tired of mathematics while studying hard, which is becoming more and more serious. What math knowledge can you ask many people to use after they leave school? The answer is no, which is the sorrow of mathematics teaching. As Professor Liu Jian said, we pay more attention to the mastery of "mathematical knowledge" in "mathematical education", but in fact less than 1% of people will engage in jobs directly related to mathematics. This obviously only pays attention to a few people and ignores the needs of the vast majority of people. This requires teachers to introduce mathematical culture into teaching and make mathematics useful.

Strategy 1: Construct the target system of classroom teaching of mathematical culture.

Mathematics, as a kind of education of cultural system, enables students to develop in knowledge education, emotional education, intellectual development, mathematical aesthetics and mathematical cultural concepts through mathematics. The goal system of mathematics culture classroom teaching should be constructed as follows: educational goal (knowledge and skills)-cognitive value; Development goal (process method)-practical value; Educational goal (emotional aesthetics)-aesthetic value.

Strategy 2: Create a teaching atmosphere of mathematics classroom culture.

1. Advocating teaching democracy

Teaching democracy can provide students with a relaxed and harmonious learning environment and create an equal, democratic and relaxed learning atmosphere. In this atmosphere, students dare to think, ask and speak, and their thinking is in a positive state, which will make them devote themselves to learning, experience the happiness of mathematics learning and deepen their feelings for mathematics culture.

2. Strengthen independent activities

Let students do activities by themselves, that is, leave the space for thinking and time for research to students, give full play to their enthusiasm and initiative in learning, so that their personalities can be fully displayed and their potential can be fully developed. The new textbook is based on students' surrounding world and real life, presenting rich and interesting learning materials, providing students with opportunities to freely express, question, explore and discuss problems, allowing students to solve real-life problems through independent thinking, independent inquiry and cooperative communication, and feel the value embodiment of mathematical culture in life.

3. Create learning situations

As an art subject, mathematics contains many interesting, wonderful, unique and magical knowledge mysteries. It is undoubtedly a pleasure for teachers to actively develop applications, present interesting mathematical cultural contents vividly and interestingly, and guide students to discover, taste and enjoy.

Strategy 3: Reveal the connotation of mathematical culture.

1. Let students understand the generation and development of mathematical knowledge.

When teaching "Understanding Scores", you can set up such a teaching situation, so that students can open their textbooks and look at pictures and talk about the generation of scores. When an integer result cannot be obtained by dividing an object, a score is generated. In ancient China, scores were expressed by calculation. When Indians invented Arabic numerals and Arabs invented fractional lines, fractions became the present expression. This is enough to show that with the unremitting efforts and the spirit of Excellence of mathematicians, the expression of fractions will become more and more concise, and we can still use letter symbols to represent all fractions in the future. In addition, students should understand that the generation of scores is based on "average score" and realize that "average score" is the fairest and most reasonable score.

2. Show the application of knowledge points in textbooks in real life.

For example, when I was teaching Angle, I dug up many examples of the application of angle from the real thing: (1) The standard lens and wide-angle lens of the camera can change the shooting range. Generally, the shooting range of standard lens is between 45 degrees and 50 degrees, while the shooting range can be expanded by using wide-angle lens. (2) What is the appropriate angle to look at the kindergarten slide? According to experts, it is known that the slope of the landslide is between 40 degrees and 56 degrees. (3) How appropriate is the backrest of the student chair?

3. Let students understand the relationship between mathematics and other disciplines.

When learning "Fractions and Percentages", we can provide students with such mathematical and cultural information: Wang Juzheng, a scientist in China, has a proverb about experimental failure, which is called "There is still 50% hope to continue, and if you don't do it, there will be 1000% failure." Edison, the great inventor, described genius with an equation. He said: "Genius = 1% inspiration +99% sweat." These "maxims" not only reflect the great man's life belief, but also reflect the brilliance of mathematics.

4. Let students know the outstanding contributions of mathematicians.

After learning "divisible number", it is necessary to introduce the famous "Goldbach conjecture" to students. He believes that "any even number greater than 2 is the sum of two prime numbers." At that time, no one cared. After 200 years, this conjecture was like a solid fortress, motionless. China mathematician Chen Jingrun proved "1+2" that shocked the world in 1966. It is of great significance to let students know the contributions of mathematicians and make them idols in their hearts. In addition, let students write math stories, math papers, guess math riddles, write math nursery rhymes, participate in some math knowledge contests and math intelligence games, and do some math newspaper clippings, which can promote students' knowledge and understanding of math culture. At the same time, through practical creation, we can also achieve the purpose of spreading interest, passion and enlightenment with beauty.

5. Let students feel interesting stories and anecdotes in mathematics.

Why are the "black hole", "affinity number", "perfect number" and "twin number" all valuable resources in the classroom teaching of mathematics culture and become a beautiful feast in the life of mathematics culture? If it is excavated, students will have a strong interest and desire to explore.

Mathematics can not only promote the development of logical thinking, but also cultivate people's creativity. In primary school mathematics teaching, we should make use of the cultural value of mathematics science, tap the thinking method, values and aesthetic taste contained in mathematics curriculum, and cultivate students in mathematics learning. As knowledge, you don't need to remember it for life, but the spirit of mathematics will inspire you for life; Problem-solving skills do not need to be mastered for life, but ideas and their cultural philosophy will be used for life. It is a realistic value pursuit to infiltrate mathematical culture into primary school mathematics teaching.
