"China Cup" is a national large-scale youth mathematics competition held in memory of Professor Hua, an outstanding mathematician in China. It was founded in 1986. China Cup is the largest, most formal and most difficult primary school competition in China.

Competition time: the preliminary competition is held in early March every year; The rematch is held at the beginning of April every year. The finals will be held in July;

Another way to enter the finals: sign up for the China Cup Winter Camp (held on June 5438+ 10 every year, and the first prize can directly enter the China Cup National Individual Finals).

Grade: primary school group (grade five or six) and junior high school group (grade one)

Features and functions of cups:

1, "China Cup" is the only national mathematics competition that has been strictly selected in three rounds: preliminary competition, semi-final competition and final competition.

2. "China Cup" is the only series of math competitions with multiple supporting activities. Including the national finals, the "China Cup Classic Competition across the Taiwan Strait" and the "China Cup Winter Camp".

3. As the most authoritative primary school mathematics competition in China, Huabei has been recognized by key middle schools in Beijing.

The initial test time of China Cup is short, the number of questions is small, the difficulty is low, and the difficulty gradient is small, so the average score of the test is high, and the score of entering the semi-finals is also high. However, due to the wide gradient, great difficulty and many types of questions, the final exam of China Cup takes a long time (one and a half hours). However, the China Cup has the highest gold content, the most stable entrance guarantee, the highest level of competition questions and the largest final. "China Cup" is one of the major events that outstanding primary and secondary school students must participate in, key middle schools must pay attention to and junior high school students must refer to.

Demonstration of Mathematical Problem Solving Ability (Spring Cup)

(star of difficulty)

"Spring Cup" is a traditional competition for primary and secondary schools in Beijing, which has played a great role in stimulating students to learn mathematics, discovering outstanding mathematical talents and promoting the reform of mathematics teaching in primary and secondary schools in Beijing. Later, it was renamed as a demonstration of mathematical problem-solving ability.

Competition time: the preliminary contest will be held at 65438+ in early February every year, and the rematch will be held in early February of the following year.

Grade: students in the middle grade group (grade three or four) and students in the senior grade group (grade five or six).

Features and functions of cups:

1, the difficulty of winning prizes in lower grades is reduced: many parents in lower grades are unaware of the pressure of competition. At this time, if they can get some excellent results in the competition awards first, they can not only increase the weight of the competition, but more importantly, they can increase their learning confidence and interest, and then get room for continuous progress.

2. The Spring Cup is a qualifying tournament for many important competitions: for example, the China Cup Elite Invitational Tournament, the Walking American National Finals, the Japanese Arithmetic Olympiad and other domestic and international competitions participated in last year, and the entry standard is to win the third prize of the Spring Cup or above.

Judging from the gold content of the awards, the topic types and difficulty settings of the Spring Festival Cup have a relatively high level. It can objectively examine students' knowledge of Olympic mathematics and the flexibility of mathematical thinking to a great extent. In 2009, the level of the preliminary examination questions was consistent, and the difficulty of the examination questions was controlled at a very high standard. This is one of the reasons why many key middle schools attach great importance to the results of the Spring Festival Cup.

Walk into the wonderful mathematics garden

(star of difficulty)

As a rising star in mathematics competition, "Walking Beauty Cup" has made rapid development with its novel examination form and high competition difficulty, and has attracted wide attention in the selection of key middle schools in recent years.

Competition time: 00: 00 in late March in the preliminary round and 00: 00: 00 in July in the national finals.

Grade: students from grade three in primary school to grade two in junior high school.

Features and functions of cups:

1, "Walking Beauty" is the only competition among the four cups that only needs one test to select the final prize. This is beneficial to most students, and there is no trouble of wasting energy because the front is too long.

2. Walking America has a high proportion of awards, which is very beneficial for middle-level students to compete for high-end awards.

The characteristics of the test questions are impartial and difficult, emphasizing the examination of students' basic mathematical ability and basic knowledge of Olympic mathematics.

Hope cup

(star of difficulty)

Since its establishment, Hope Cup has always been oriented to most schools and students. Every link from proposition, award presentation and organization revolves around one purpose: to stimulate middle school students' interest in learning, cultivate their self-confidence, and constantly improve their ability and quality without increasing the burden on teachers and students, so it is welcomed by teachers and students.

Competition time: the preliminary competition will be held in early March and the semi-finals will be held in early April every year.

Grade: Grade 4, 5 and 6 in primary school, Grade 1 and Grade 2 in junior and senior high schools.

Features and functions of cups:

1, Hope Cup is held for all primary school students. The number of students participating in the training course is huge and their level is uneven, so it is not so difficult for students participating in the training course to win prizes.

2. Hope Cup pays attention to the effective combination of in-class and out-of-class, so the selected students can be summarized as strong comprehensive learning ability, strong comprehensive strength and excellent study habits. This category is only recognized by most key middle schools.

First of all, the preliminary test questions of Hope Cup are simple, but the scoring rate is quite high. Under the guidance of parents, many students think that the Hope Cup is for ordinary students, so "excellent students" should take the exam casually, which is very incorrect. Take the Hope Cup in 2008 as an example: 20 questions, and the standard for entering the semi-finals is 18, which is not easy for any "excellent student".

Secondly, the hope cup has a low pass rate in the initial test and a high success rate in the second test. The pass rate of preliminary and semi-finals is 25%, which is relatively low in all cup competitions. After entering the second interview, 40% of the students have a chance to win the prize. Therefore, in the preliminary round of the Hope Cup, we must not underestimate the enemy. We must seriously study the real questions and sum up the ideas of the questions in order to be foolproof.

Third, there are many traps in the test questions of Hope Cup. Occasionally, there may be some digression and it is easy to lose points. For example, the question 1 1 in 2008: What is the angle between the hour hand and the minute hand on the clock face at the moment of 16 and 16? Many students have not mastered the correct solution to this problem: using trip problem to solve it. One kind of students directly calculate the angle, which is easy to make mistakes. The other kind of students try to work out the results, but it takes too long, resulting in insufficient time for other questions. In addition, last year, the sixth grade also inspected the segmented travel of travel questions, and many students were not easy to get the correct answer.

Finally, the preliminary competition time of Hope Cup is close to that of China Cup, and students' examination strategies are easy to be misused. Many students don't pay much attention to the Hope Cup, but the ideas and styles of the Chinese Cup and the Hope Cup are completely different, which easily leads to mistakes in examination ideas and strategies and improper grasp of the difficulty of the topic. In 2008, more than a dozen competition experts selected for the China Cup Classic only won the third prize of Hope Cup, which shows that Hope Cup is different.
