1. Starting from daily life, create vivid and interesting problem situations, attract students' attention, stimulate students' interest in learning, make students learn and understand mathematics in the process of studying practical problems from life experience and objective facts, and apply the learned mathematics knowledge to real life, so that students can get close to mathematics and feel the joy of learning mathematics, which initially reflects the connection with current life. 2. Motivation, in teaching, pay full attention to the changes of students' emotional attitudes, adopt positive evaluation, use more encouraging language, mobilize students' desire to actively explore knowledge, stimulate students' enthusiasm for learning, and let each student experience success and enhance self-confidence. As far as teaching is concerned, teaching students knowledge, methods and the ability to think, analyze and solve problems independently should be the professional pursuit of teachers. 3. Let students become the masters of classroom learning. Under the new curriculum, teachers should become the organizers, guides and collaborators of students' learning, stimulate students' learning enthusiasm and creativity, provide students with opportunities to engage in activities, build a platform to carry out research, and let students become the masters of learning. 4. Flexible use of mining materials. In the teaching process, teachers should learn to use teaching materials flexibly and actively according to students' cognitive rules and current level, and at the same time, carefully understand the intention of compiling teaching materials, and make necessary additions and deletions according to students' reality, so that the limited teaching materials can be extended indefinitely. 5. The pursuit of the unity of form and effect of the classroom. First of all, the problem situation must be close to students' real life, and the activity content must be synchronized with students' existing knowledge structure and cognitive level; Secondly, let students have an independent thinking process, let them fully discuss and learn from their own viewpoints, find their own shortcomings, and build a complete and comprehensive knowledge system; When students' feelings of equality and mutual respect are satisfied, they will easily and comfortably devote themselves to their studies and actively explore. Therefore, modern classroom teaching should establish the teaching concept of equality between teachers and students, build a teaching platform of equal dialogue, let teaching be carried out in the process of equality between teachers and students, let the relationship between teachers and students be understood as comfortable cooperation, and let students study in an atmosphere of psychological relaxation, concentration, active thinking, dare to think, dare to ask, dare to say and dare to do. 6. Be familiar with the importance and common methods of mastering the new high school mathematics curriculum as a whole. Grasping the new high school mathematics curriculum as a whole can not only make us clearly understand the main context of high school mathematics, but also enable us to stand on a higher level and face the new high school mathematics curriculum with the attitude of "learning from other mountains" ... Mastering the new high school mathematics curriculum as a whole can not only improve teachers' own quality, but also help to cultivate students' mathematical literacy. Therefore, for a high school math teacher, it is very necessary and meaningful to master the new high school math curriculum as a whole and clearly understand and grasp the main line of mathematics. Combining individual wisdom with collective wisdom is one of the effective ways to grasp the main context of mathematics. Scientific thinking mode can make students make ends meet and get twice the result with half the effort. Appropriate situational guidance can stimulate students' interest and motivation in autonomous learning. Therefore, the integration of individual wisdom and collective wisdom for induction, summary and communication can promote us to produce more and better teaching methods and newer scientific thinking modes. This is of great practical and far-reaching significance for us to improve the quality of classroom teaching. 7. Through some teachers' detailed classroom case analysis and experts' classic comments on the Internet, I realized how to grasp the classroom teaching of senior high school mathematics. How to run through the main line in the daily teaching process? An excellent teacher should achieve the following two purposes by grasping classroom teaching: on the one hand, through our daily teaching, we can effectively help students improve their academic performance in order to enter an ideal university for further study; On the other hand, fundamentally improve students' comprehensive quality and lay the foundation for future sustainable development. The arrangement and design of the new textbook fully embodies the editor's good intentions. As teachers, we should better serve students and society through our own and collective creation. 8. The content arrangement of the new textbooks truly reflects the idea that mathematics comes from life and serves life. Most of them use mathematical problems in daily life as an introduction to cultivate students' interest in learning and stimulate their enthusiasm for learning. 9. Make full use of modern educational technology to serve teaching. The development of modern science and technology and the popularization of computers provide convenience for modern teaching. Our teachers should make full use of modern educational technology to assist teaching, provide students with a more intuitive and vivid impression and deepen their understanding of knowledge. Teachers can also use network resources to provide students with richer learning resources. Get out of the traditional classroom, broaden students' horizons, enrich teaching content, let students learn knowledge that books can't learn, and improve teaching quality.
