In a word, the key to improve math performance is to grasp the overall situation, highlight the key points, grasp the foundation and improve the ability. Review the knowledge learned in junior high school, highlight the main knowledge, strengthen the review of teaching priorities, systematically sort out the knowledge learned and integrate it into a knowledge system. Understand the basic mathematical thinking methods and strategic thinking of analyzing and solving problems; Master the law of solving problems, draw lessons from experience and improve the quality of mathematical thinking, and you will definitely become a top student in mathematics. The ninth grade is now facing the review of the senior high school entrance examination, but it is still superficial to say how much mathematics teaching experience the ninth grade has reviewed. More importantly, in the teaching work, constantly update the curriculum standards, constantly improve the teaching methods and means, and constantly update the questions for further study. Even so, my experience in mathematics teaching is constantly summarized, and I dare not neglect the work of mathematics teaching. In the teaching work, I earnestly study new teaching concepts, learn from others' good teaching methods with an open mind and apply them to my own teaching work, so as to further improve my teaching level and make ninth-grade graduates achieve better graduation results. The following is a brief summary of my own mathematics teaching experience.
