How to set the goal of ninth grade mathematics teaching;
Guided by Deng Xiaoping's thought of "Three Faces", we should further carry forward and implement the spirit of "New Curriculum Standards for Junior Middle School Mathematics", take students' development as the foundation, change learning methods as the goal, train high-quality talents as the goal, and cultivate students' innovative spirit and practical ability as the focus of quality education, and explore new effective teaching modes. The basic starting point of mathematics curriculum in compulsory education stage is to promote students' all-round, sustained and harmonious development. We should not only consider the characteristics of mathematics itself, but also follow the psychological laws of students' learning mathematics, and emphasize that starting from students' existing life experience, students should experience the process of abstracting practical problems into mathematical models and explaining and applying them, so that students can gain an understanding of mathematics and make progress and development in thinking ability, emotional attitude and values. Focusing on classroom teaching, closely surrounding the "basic requirements" of junior high school mathematics textbooks and mathematics subjects, this paper studies the changes and trends of senior high school entrance examination propositions in recent years, collects test papers, selects exercises, establishes a question bank, strives to grasp the direction of senior high school entrance examination, actively explores efficient review ways, strives to achieve the purpose of reducing burdens, boosting pressure and increasing efficiency, and strives to achieve good results in senior high school entrance examination.
Second, the teaching objectives:

Carefully study the teaching materials and syllabus, make clear the teaching objectives, grasp the key points and difficulties, carefully design the teaching process, pay attention to the relationship and position between the content of each chapter and the knowledge before and after class, pay attention to after-class reflection, and design the details of teacher-student interaction in each class.
(2) Good class: On the basis of preparing lessons, each class is taught for 45 minutes to improve the efficiency of 40 minutes so that every student can understand it. The poor foundation should be gradual, and the difficulty of choosing examples is different, so that every student can "eat" and "eat" well.
(3) Pay attention to after-class reflection, record the gains and losses of a class in time, and constantly accumulate teaching experience.
(4) Batch each assignment: the assignment reflects the effect of a class, how well the students master the knowledge, and carefully correct the assignment, so that the teacher can quickly grasp the situation and prescribe the right medicine.
(5) Check the learning results on time to ensure that the unit test is effective and timely, and the test paper will not be corrected overnight. After the exam, comment on students' psychology of wanting to know the answer immediately after using typical mistakes.
(6) Timely guidance and correction: strive for face-to-face signing and face-to-face teaching. Don't put off today's task until tomorrow, strive for every moment and firmly grasp every minute of Grade Three. Feedback after class. Choose appropriate exercises and papers, correct homework in time, point out problems to students face to face in time and guide them to understand, leaving no difficulty for students to gain something.
