Lifelike folk paper-cut window grilles, and even each of us and every smiling face, don’t you feel the power of symmetry... The above teaching activities have the following characteristics in penetrating mathematics culture ,

1. Pay attention to the cultural attributes of mathematics classrooms. Mathematics has its own rich cultural origins, but the boring and rote teaching method has always been a stumbling block that hinders students from learning mathematics. The reason for this phenomenon is There are many aspects: First, it blindly pursues the transmission of mathematical knowledge and the training of mathematical skills; second, it downplays the cultural background contained in mathematics itself. Ignoring the nature of human beings' continuous exploration and discovery that is immersed in the development and evolution of mathematics, as well as the inextricable connection between mathematics and life, the above four-step teaching design aims to explore the rich (nature) hidden in mathematics. and human society) cultural resources, achieve the harmonious unity of their scientific value and humanistic value, and cultivate students' innovative spirit of continuous exploration and discovery.

2. Pay attention to strengthening the cultural penetration in mathematics activities. Mathematics activities are an important part of mathematics teaching. Carrying out rich and colorful mathematics activities can give full play to students' initiative and allow students to be culturally influenced in the learning process. Infect and experience the cultural taste of mathematics. Playing with symmetry can make students question and arouse their desire for knowledge; knowing symmetry can help students master knowledge and grow their talents; doing symmetry can develop students' interests, hobbies and specialties, and improve their learning ability; appreciating symmetry can make students Realize that symmetry is a kind of beauty, understand some characteristics of the motherland's culture, and broaden your knowledge.

3. Strive to allow students to accept the influence of mathematical culture. In the teaching design, try to collect materials that can reflect the beauty of symmetry, and attract students with the unique charm of the mathematics subject itself, such as the beauty of symmetry in life, the beauty of symmetry, and the beauty of symmetry. The symmetrical beauty of nature and the symmetrical beauty of ancient and modern architecture. While students feel and appreciate the beauty of mathematics, their thinking has flown out of the classroom and into the distant world of mathematics, giving rise to the impulse and desire to create mathematical beauty.
