Developed by chinese mathematical society Popularization Committee
Under the guidance of the policy of "improving on the basis of popularization", the national mathematics competition is in the ascendant. Especially in recent years, Chinese athletes have made gratifying achievements in the international mathematics Olympics, which has inspired teachers, students and mathematicians in primary and secondary schools, and their enthusiasm has been rising, and the mathematics competition has entered a new stage. In order to make the national mathematics competition sustainable, healthy and in-depth step by step, the outline of mathematics competition is formulated at the request of the teachers and students of middle schools and the coaches of mathematics Olympics at all levels to meet the needs of the current situation.
This syllabus is based on the spirit and foundation of the "Full-time Middle School Mathematics Syllabus" formulated by the State Education Commission. The syllabus points out in the column of teaching purpose: "To realize the four modernizations, we must cultivate students' interest in mathematics and stimulate them to learn mathematics well. "The concrete measures are:" For students who have spare capacity for study, they should fully develop their mathematical talents through extracurricular activities or offering elective courses ","We should pay attention to the cultivation of their abilities … ",and pay attention to cultivating students' computing ability, logical thinking ability and spatial imagination ability, so that students can gradually learn important thinking methods such as analysis, synthesis, induction, deduction, generalization, abstraction and analogy. At the same time, we should pay attention to cultivating students' independent thinking and self-study ability. "
The contents listed in the syllabus are the requirements of teaching and the minimum requirements of the competition. In the competition, there are higher requirements for the understanding and flexible application of the same knowledge content, especially the proficiency of methods and skills. And "classroom teaching is the main thing, supplemented by extracurricular activities" is the principle that must be followed. Therefore, the extracurricular teaching contents listed in this syllabus must fully consider the actual situation of students, so that students can master them step by step and at different levels, implement the principle of "less but better", strengthen the foundation and constantly improve. From 20 10, the new rules of the national high school mathematics league test questions are as follows:
The league is divided into a test and an extra test (commonly known as the "second test"). The "preliminaries", "preliminaries" and "rematch" organized by provinces are not the official names and procedures of national leagues.
The initial test and additional test are conducted on the first Sunday in the middle of June 5438+ 10 every year.
Just try it.
The examination time is 8: 00-9: 20 am, and ***80 minutes. The test questions are divided into two parts: fill-in-the-blank questions and solution questions, with a full score of 120. Among them, there are 8 fill-in-the-blank questions, with 8 points for each question; Answer 3 questions, 16, 20, 20.
(The old rules in 2009 and the rules before 2008 are omitted. )
Additional test (second test)
The examination time is 9: 40- 12: 10, *** 150 minutes. The test questions are four solutions, with 40 points for the first two questions and 50 points for the last two questions, with a full score of 180. The test questions involve plane geometry, algebra, number theory, combinatorial mathematics and so on.
(The old rules in 2009 and the rules before 2008 are omitted. )
According to the test results, the provincial first, second and third prizes were selected. Among them, the provinces are responsible for judging the first prize, and then send the test paper of the first prize to the organizer (the organizer of the year), which will be re-evaluated by the organizer, and finally the competent unit (China Association for Science and Technology) will be responsible for the final evaluation and announcement. The second prize and the third prize are decided by the provinces.

Formulated by chinese mathematical society Popularization Work Committee
(August 2006)
Since 198 1 the National Senior High School Mathematics League was held by the chinese mathematical society Popularization Committee, under the guidance of the principle of "continuous improvement on the basis of popularization", the national mathematics competition is in the ascendant, attracting millions of students to participate in it every year. From 65438 to 0985, China stepped into the International Mathematical Olympiad, which strengthened the international exchange of extracurricular mathematics education. In the past 20 years, China has become one of the powerful countries of the International Maritime Organization. Mathematics competition plays a positive role in developing students' intelligence, broadening their horizons, promoting teaching reform, improving teaching level and discovering and cultivating mathematics talents. This activity has also stimulated teenagers' interest in learning mathematics, attracted them to actively explore, and constantly cultivated and improved their creative thinking ability. The educational function of mathematics competition shows that this activity has become an important part of middle school mathematics education.
In order to make the national mathematics competition sustainable, healthy and in-depth, chinese mathematical society Popularization Committee has formulated 1994 "Outline of High School Mathematics Competition", which has played a good guiding role in the development of high school mathematics competition, and the activities of high school mathematics competition in China are becoming more and more standardized and regular.
At the same time, with the development of mathematics competitions at home and abroad, there are some new requirements for the knowledge, ideas and methods involved in the competition, and the original high school mathematics competition outline can no longer meet the development and requirements of the new situation. After extensive consultation and many discussions, the outline of senior high school mathematics competition was revised.
This syllabus is based on the spirit and foundation of Mathematics Syllabus for Full-time Senior Middle Schools. "Mathematics Teaching Syllabus for Full-time Senior Middle Schools" points out: "To promote the development of every student, we should not only lay a good foundation for all students, but also pay attention to developing students' personalities and specialties; ..... In class and extracurricular teaching, it is advisable to proceed from the reality of students, take into account students with learning difficulties and spare capacity, meet their learning needs through various ways and methods, and develop their mathematical talents. "
Students' mathematics learning activities should be a lively and personalized process, which should not be limited to acceptance, memorization, imitation and practice, but also advocate reading self-study, independent exploration, hands-on practice and cooperative communication, all of which are helpful to give full play to students' initiative in learning. Teachers should give specific guidance according to students' different foundations, levels, interests and development directions. Teachers should guide students to actively engage in mathematics activities, so that students can form their own understanding of mathematics knowledge and effective learning strategies. Teachers should stimulate students' enthusiasm for learning, provide them with opportunities to fully engage in mathematical activities, and help them truly understand and master basic mathematical knowledge and skills, mathematical ideas and methods in the process of independent exploration and cooperative communication, so as to gain rich experience in mathematical activities. For students who have spare time to study and have a strong interest in mathematics, teachers should set up some elective contents for them, provide them with enough materials to guide them to read and develop their mathematical talents.
The contents listed in "Mathematics Teaching Syllabus of Full-time Ordinary Senior Middle Schools" in 2000 by the Ministry of Education are the requirements of teaching and the minimum requirements of competition. In the competition, for the same knowledge content, there are higher requirements in understanding, flexible application ability and proficiency in methods and skills. "Classroom teaching is the main thing, and extracurricular activities are the auxiliary thing" is the principle that must be followed. Therefore, the extracurricular teaching contents listed in this syllabus must fully consider the actual situation of students, so that students of different degrees can develop correspondingly in mathematics and implement the principle of "less but better". The scope of knowledge involved in "National Senior High School Mathematics League (Trial)" does not exceed the full-time senior high school mathematics syllabus published by the Ministry of Education in 2000.
