Everyone can get a good math education, and different people have different development in math. Based on the existing experience, it is oriented to all students and pays attention to heuristic and personalized teaching. Everyone can get a good math education, which requires our teachers to respect students' existing learning experience and leave the learning space for students to explore independently, so that students can master knowledge and learn new knowledge in independent discussion. Experience the practice of mathematics and life, and understand the truth that "mathematics comes from life and is used in life". Let every student get a good math education. Different people get different development in mathematics. Based on the existing experience, they are oriented to all students and pay attention to heuristic and personalized teaching. My understanding is that teaching or students are the main body, and teachers are the organizers, guides and collaborators of the school. We should teach students in accordance with their aptitude according to their experience in the teaching process. We don't impart knowledge to students, but inspire students to discover knowledge, understand knowledge, and finally apply knowledge to life. Solving practical problems with mathematical knowledge. That is, our teaching should be effective, and effective teaching should be the unity of students' learning and teachers' teaching.
