Mathematics classroom should strive to create a strong atmosphere of autonomous learning of middle school mathematics composition, stimulate students' interest in learning middle school mathematics composition, mobilize students' learning potential, and make them truly masters of classroom learning. Teach life experience, make mathematics problems come alive, and make primary school mathematics education a lively, personalized, independent learning, exploration and cooperation process. Key words: Mathematics Practice "New Curriculum Standard" clearly points out that effective learning activities cannot rely solely on imitation and memory, and hands-on practice, independent inquiry and cooperative communication are important ways for students to learn mathematics. There used to be some ideas that academic success was manifested in the possession of mathematical knowledge (repetition or reproduction) and the solution of problems (artificial and untrue). Obviously, in their consciousness, mathematics education has become a process of self-accumulation and development that is divorced from social reality, closed, copied and reproduced. With the deepening of modern teaching reform, mathematics classroom pays more attention to actively improving traditional teaching methods such as explanation, demonstration and examples, and strives to create a strong autonomous learning atmosphere, stimulate students' interest in learning, mobilize students' learning potential, and make them truly masters of classroom learning. "Teaching life experience, making mathematics problems live, and making primary school mathematics education a lively, personalized, autonomous learning, exploration and cooperation process" is the direction of current teaching work. First, in the classroom, create a reasonable situation-let students enjoy learning. "Mathematics education should strive to stimulate students' learning emotions, link mathematics with students' life and study, and learn dynamic and vivid mathematics" is a passage in a newspaper. It is not difficult for us to realize this teaching.
