2. American senior high school math competition (AMC 10/ 12, American math competition 10/ 12) takes part in high school and below students. Since 2000, it is usually held on Tuesday in early February every year, and the competition time is 75 minutes. The competition questions consist of 25 multiple-choice questions. Correct answer. Total score 150. The purpose of the competition is to encourage students to solve mathematical problems with interest, and to determine their comprehensive problem-solving ability through such an attractive examination. In addition, its main purpose is to improve students' interest and ability in mathematics by solving exciting and challenging problems. Another special purpose is to help excellent students in mathematics. The content of the competition is high school mathematics except calculus. The multiple-choice questions and solutions all illustrate an important mathematical principle. Sometimes, the selected answers to some questions will list subtle but not accidental confusions and common calculation errors, and some problems have quick "technical" solutions. These methods seem to be skills when they first appeared, and they are techniques to solve a large number of problems; Because of these skills, students' mathematical skills and methods will be greatly improved and expanded. Because the examination questions are designed for everyone from ordinary students in general schools to outstanding students in key schools, the arrangement of examination questions is from easy to difficult, and candidates will find that most of the questions are challenging but within their power. Because of the wide range of pseudo-ability and pseudo-knowledge, the scores of candidates are widely distributed. Generally speaking, the proportion of candidates with AMC 12 100 or above or AMC 10/20 or above is relatively low. These students will be invited to participate in the American Teaching Invitational Tournament, and high school students and junior high school students will have the opportunity to participate in AMC1012 for many times and proudly discover the changes of their abilities.
3.AIME (American Invitational Mathematics Test) 1983 begins and AMC1012A is held in the last five weeks. The examination time is 3 hours, and the contest questions are composed of "15 questions, and the answers are integers from 0 to 999. If you answer a question correctly, you will get it. The perfect score is 15. The test questions are quite difficult, and candidates generally can't get the correct answer by guessing. The content of the test is that in addition to integral in middle school mathematics. For example, American high school math competition and American math Olympics can be solved by middle school teaching methods that do not exceed calculus. . AIME aims to unite with AMC to identify outstanding students in mathematics in the previous stage of university. Choose the participants of the American Mathematical Olympiad. This test attempts to provide high school students who have advantages in mathematics with a challenge and an opportunity to know their talents. Like other competitions, the test provides a way to further develop their mathematical talents and improve their interest in mathematics. In fact, the value lies in the preparation before the exam and the further thinking and discussion on the exam questions after the exam, which is the focus of this paper.
4. The United States of America (Junior) Mathematical Olympiad (USA(J)Mo) 1972 (USAJMO 20 10) was held six weeks after AIME; The examination time is divided into two days ***9 hours. It consists of 6 questions, answers and proofs, with 7 points for each question, and extra points for incomplete answers and proofs. Examination questions can be solved mathematically before calculus. The purpose. USAMO is to find and challenge middle school students with outstanding talents (superb originality, rich mathematical knowledge and excellent computing expertise); Explore the mathematical talents of these students, who may be the elite in the next field of algebra. Every year, about 260-270 students with high scores based on AMC 12 and AIME are invited to take the USAMO, and 230-240 students with high scores based on AMC 10 and AIME are invited to take the USAJMO. Only American citizens or legal residents of the United States are eligible to take this exam. There was no such requirement in previous competitions.
Calculators are prohibited in the above competitions. . AMC and AIME welcome foreign students to participate.
5.MOSP (Mathematical Olympiad Project) consists of about 50 promising students (including 6 members of the American team of the International Mathematical Olympiad) and teachers. . USAMO winners who are not in 12 grade and USAMO honorary prize winners will be invited. In addition, there are outstanding students in grade 9 of USAJMO or 10, and girls in grade 8- 10 are preparing for the Chinese Women's Mathematical Olympics. Summer camp will provide students with rich knowledge and profound contents in some important mathematics fields, so as to stimulate them to maintain and improve their interest in mathematics and make full preparations for further study of mathematics. These contents include combinatorial argument, generating function, graph theory, recursive relation, embedding and product, probability, number theory, polynomial, equation theory, complex number, algorithm proof, function equation, Ramsey theorem, geometry, pigeon hole principle, including exclusion, classical inequality and so on (traditionally, compared with other countries, these contents are not paid much attention to in American schools), and only by deeply understanding these contents can we learn them. The summer camp also strives to create a friendly cooperative relationship among the participants, so that they can feel the happiness and self-esteem of cooperation. The summer camp ensured the performance of the American team in the International Mathematical Olympiad. It appropriately embodies the best learning ability and creativity in the United States. After the four-week summer camp, the U.S. team composed of the top six USAMO participated in the International Mathematical Olympiad (depending on the situation, such as 20 1 1, the selection of American IMO players depends on their performance in MOSP and various competitions, and 20 12, they are the top six USAMO).
6.IMO (International Mathematical Olympiad) The International Mathematical Olympiad began in 1959, and the United States began to participate in 1974. 1July, 997, in the 38th International Mathematical Olympiad, the total score of the United States team was 202 (tied for fourth place). The American Middle School Mathematics Competition Committee agreed that the purpose of the American team's participation in IMO is: to provide the American team with an opportunity to contact and exchange with mathematicians and scientists from other countries, and to accumulate MOSP's experience in cultivating and educating outstanding students; After the United States team participated in IMO, the publicity and concern of the public, as well as the example of outstanding students, inspired and inspired outstanding talents among American middle school students and teachers; Taking this attractive competition as a forum to exchange ideas on mathematics and mathematics education is conducive to determining the focus of mathematics in American middle schools; In order to promote the unity between countries, mathematics can play a role in this respect, because it is cosmopolitan.
