Visual Identity represents the symbol and story of a theme or thing. Visual identity is often called a logo. There are many signs in life, symbolizing the brand image and the brand's founding philosophy. How to embed visual identity into the minds of the public, use it systematically, and make the logo significant and attractive is the teaching goal of art teachers. The meaning and symbol of a logo are not only the formal elements of beauty, but also include the presentation of mathematics: points, straight lines, angles, shapes, coordinates, etc. The formal principles of beauty are combined with the elements of music. With this starting point, we designed a series of course activities. We expect that during the students’ three years of junior high school, we will gradually achieve our goal: students plan their own concerts, including the arrangement of music tracks, the design of invitation cards, program lists, and even the production of concert souvenirs. There will be exhibitions of works in six major fields: "art, performing arts, music", mathematics, Chinese language, English, comprehensive activities: "tutoring", and science and technology. Under such a goal, we set out to establish students' aesthetic foundation in the first-grade curriculum, and break the boundaries between subjects. Using geometric figures in mathematics classes, we enable students to start making tangrams and let students experiment with arranging rich figures. , create aesthetically pleasing images in art classes. In the music class, the concept of the square grid in the mathematics class is continued, allowing students to understand the composition of each trial beat, and combine the feelings of rhythm with black, gray, and white to form a picture to complete this "Rhythm Code-Dance Number" course.
