Tomorrow is the math competition, what should I pay attention to?

The first is that you can't be nervous and it's important to stay in good shape.

You can't think about whether you are right or not with the teacher, otherwise your state during the exam will be disrupted, and even the questions you can start with may not be able to perform properly. When you take the exam, you just want to do your best, take the questions you can do right one by one, and get yourself in a good state.

Secondly, you need to be confident, you can have only two places in a class, which means that you still have strength in the teacher's mind, otherwise why would he choose you?

Now what you have to do is to use the limited time to try to recall the methods that the teacher has taught, take some important test papers to see, and you can also find some questions to practice and find the feel. There are very few things that are really difficult in junior high school competitions, and most of them are the elevation of knowledge learned in school, so you don't have to be nervous.

Also, go to bed early tonight, of course, not too early, just arrange it according to the usual biological clock.

As for the things you need to pay attention to in the exam, you have to get enough points for what you can do and do it right, and then do the difficult problems. Of course, don't skip that question just a little bit of stuck, at least you need to calm down and think carefully, and skip it if you really can't. (Math contests generally don't allow calculators, but just in case you bring them).

Last but not least, good luck!

Rest well and be in a good mood! I'm sure you'll win!! Also, eat some chocolate before the exam, it works well, really, I tried it.

Also, drink a little ginseng water、、、 I hope you can give me my opinion, thank you for a good rest, hold a good mood! I'm sure you'll win!! Also, eat some chocolate before the exam, it works well, really, I tried it.

Also, drink a little ginseng water、、、 I hope you can give my opinion, thank you!

Primary school mathematics competitions are one of the most attractive forms of extracurricular activities for primary school students. Organizing primary school students to participate in mathematics competitions can stimulate students' strong interest in studying mathematics, form a good quality of courage to practice and innovate, and can also broaden students' knowledge, improve students' quality, and develop students' personality and strengths.

Problem solving skills. 1. Perfect square number.

Perfect Square Number Feature:

1) The last digit can only be ; The opposite is not true.

2) Divide by 3 to get 0 or 1 more; The opposite is not true.

3) Divide by 4 to balance 0 or balance 1; The opposite is not true.

4) The approximate number is an odd number; The opposite is true.

5) The ten digits squared of the odd number are even; The opposite is not true.

6) Odd squared single digits are odd numbers; Even squared single digits are even.

7) There can be no more square numbers between the squares of two adjacent integers.

The squared difference formula: x2-y2=(x-y)(x+y).

The perfect sum of squares formula: (x+y)2=x2+2xy+y2

The formula for the perfect square difference: (x-y)2=x2-2xy+y2

2. Ratio and proportion.

Ratio: The division of two numbers is also called the ratio of two numbers. The number before the ratio is called the predecessor of the ratio, and the number after the ratio is called the posterior term of the ratio.

Ratio: The quotient of the previous term of the ratio divided by the latter term is called the ratio.

The nature of the ratio: The preceding and subsequent terms of the ratio are multiplied or divided by the same number at the same time (except zero), and the ratio does not change. Proportion: The formula that indicates that two ratios are equal is called proportion. a:b=c:dor.

The property of proportions: the product of two outer terms is equal to the product of two inner terms (cross-multiplication), AD=BC.

Proportional: If A expands or shrinks by several times, and B also expands or decreases by several times (when the quotient of AB remains the same), then A is proportional to B.

Inverse proportionality: If A expands or shrinks by several times, and B also shrinks or expands by several times (when the product of AB remains the same), then A is inversely proportional to B.

Scale bar: The ratio of the distance on the graph to the actual distance is called the scale bar.

Proportional distribution: Dividing several numbers into several parts in a certain proportion is called proportional distribution.

Learning mathematics competitions requires sufficient interest in learning while ensuring in-class grades in order to persevere. Then you need to customize your own learning goals, which is a provincial team national set. Of course, in this learning process, you also need sufficient learning resources, and it will be better to have a coach.

Usually read more books and brush up on questions to consolidate knowledge points. If you have the opportunity, you can participate in field training, provincial team training, summer camps, etc. You can get out of the small circle where you have lived for more than ten years and see the wider world.

1. How to choose teachers for math competitions?

A: It is no exaggeration to say that choosing a good competition teacher determines more than half of the success of the competition, because a good teacher can help you avoid 80% of detours. So how do you choose a good competition teacher?

1) The first is the lecture, and the students should judge for themselves whether the teacher's lecture is useful to them. It's not that a big-name teacher is necessarily good, you have to judge for yourself, is he inspiring my thinking? Did he tell me why?

These are very important for the start of the competition, some teachers are just talking about knowledge, or just talking about the answers, and then tell you that it is obvious that you should have done it, and you will not be the ...... of your problemSuch a teacher is harmful to beginners in competitions, and the first prize he teaches is, frankly, even if it is self-taught, the first prize.

2) The second is strategy, did he show you a practical path to the first prize. If you have a road, you may not be able to win the first prize, but if you don't have a road, isn't it even more hopeless?

3) Then there is communication, it may be more accurate to teach the competition not so much as the teacher, but the coach. What is Coaching? It is to communicate with you, grasp your state at any time, take you to train, take you to recovery, and then take you to start ......There are hundreds of people in some competition classes on the market, and many people are destined to just listen to the excitement, be a sparring partner, and play soy sauce.

Summary: In addition to how to do the questions, what you need more is the idea of doing the questions, the strategic and tactical guidance of the learning direction, and a gold medal coach. Think about Lang Ping, Liu Guoliang, and Ma Junren to understand. And in the competition, mathematical ideas "problem-solving skills" competition knowledge.

It is necessary to participate in the mathematics competition.

Mathematics competitions are one of the effective means of discovering mathematical talents. Mathematics competitions in the modern sense began in Hungary. The winners of some of the major mathematics competitions went on to go on to achieve great success in their careers.

Therefore, the developed countries of the world attach great importance to mathematics competitions. Over the past ten years, China's middle school mathematics competitions have flourished, and their influence has become more and more significant.

In particular, China's middle school students have repeatedly topped the list in the International Mathematical Olympiad, which has the greatest influence and highest level, and their achievements have attracted the attention of the world, fully demonstrating the wisdom and mathematical talent of the Chinese nation. It is necessary and beneficial to know and be familiar with the domestic competition situation if you want to use your talents through mathematics competitions. Mathematics competitions are similar to sports competitions.

It was a kind of intellectual contest for teenagers, so the Soviets pioneered it"Mathematical Olympiad"The noun. Among similar intellectual competitions with basic science as the content of the competition, the mathematics competition has a long history, many participating countries, and the greatest influence.

Mathematics competitions are gradually developed from individual cities, to the whole country, and then to the whole world. For example, the Soviet Union began with Leningrad and Moscow and expanded to the whole country in 1962, while the United States did not have a national mathematics competition until 1957.

Mathematics competitions are also gradually developed from shallow to deep. In almost every country, mathematics competitions are initiated and organized by some famous mathematicians, and the test questions are very close to the exercises in secondary school textbooks, and then gradually go deeper.

At this time, the test questions are gradually out of the scope of secondary school textbooks, and of course they are still required to state the test questions in elementary mathematics language and solve them using elementary mathematics methods.

How to participate in the math competition is as follows:

1. Find out whether the mathematics association or education department in your area has organized the competition, and check the registration information on its official **.

2. To search for relevant information, you can use the search engine to enter the keyword "Mathematics Olympiad + your region" to search, and find the demolition beam to the corresponding official ** to view the registration information.

3. Consult your school's math teacher or academic affairs office to find out if there is any relevant registration information.

It should be noted that different regions may have different registration procedures and requirements, so you need to read the registration information carefully and submit the application materials as required.

Further information is as follows:

Participants must be under the age of 20 at the time of the competition and must not have any higher education than secondary school. Therefore, university students are not allowed to participate in the International Mathematical Olympiad.

1. Founded in 1959, the International Mathematical Olympiad is known as the "Mathematics World Cup" and is held once a year, and is hosted by the participating countries in turn. The purpose is to discover and encourage young people with mathematical talents in the world, create conditions for scientific education exchanges in various countries, and enhance friendly relations between teachers and students in various countries.

2. The examination process of the International Mathematical Olympiad is divided into two stupid days, and participants have one hour to solve three problems each day (from 9 am to 1:30 pm). All questions are within the scope of the recognized secondary school mathematics curriculum, and are generally divided into four categories: algebra, geometry, number theory and combinatorics.

3. Participate in the national league in mid-October every year, if the results are in the top few in the province, you can enter the provincial team and participate in the "winter camp held in the month, which is essentially a national mathematics competition, with the purpose of selecting talents for the national team";

4. The winter camp will award gold, silver and bronze medals (the gold medal can be won by multiple people at the same time, equivalent to the first prize), and the gold medalists will all enter the national training team, participate in the training camp in the month, be taught by the best competition teachers in the country, and continue to participate in the test, and finally select the members of the national team according to the multiple tests. They will represent China in the International Mathematical Olympiad.

5. Scoring criteria: 7 points for each question, with a full score of 42 points. There are two days after the competition to mark the answer sheets. Each question will be evaluated and corrected by the team leader and deputy team leader and the coordinator designated by the host country, and the final score will be determined.

The team leader will try to score as many points as possible for the participants to the coordinator, and if they cannot reach an agreement, the results will be submitted to the main examination committee for arbitration. Finally, the gold, silver and bronze scores will be determined, and the awards will be presented at the closing ceremony of the competition.

The competitions with high gold content in junior high school are: cover fiercely

1) Mathematics Competition: National Mathematics Olympiad for Middle School Students.

2) Physics Competition: National Physics Olympiad Competition for Middle School Students.

3) Chemistry Competition - National Chemistry Olympiad for Middle School Students.

4) Biology Competition - National Biology Olympiad for Middle School Students.

5) Information Contest - National Youth Informatics Olympiad (NOIP) Computer Brother Bridge Non-professional Software Proficiency Certification (CSP-J S for short).

Middle School Mathematics Contest Method

It is necessary to be familiar with the various basic question types and master the solutions. Each practice question in the textbook is based on a knowledge point, which is the most basic topic and must be mastered proficiently; There are also many basic types of exercises outside of class, and there are many ways to use them, and they are also highly targeted, so they should be able to be made quickly. Many comprehensive questions are just an organic combination of several basic questions, and once you have mastered the basic questions, you will not have to worry about solving them.

In the process of solving problems, we should consciously pay attention to the thinking methods embodied in the problems to form a correct mindset. Mathematics is a world of thinking, with many thinking skills, so each problem will reflect a certain thinking method in the process of proposition and problem solving, if we consciously pay attention to these thinking methods.

After a long time, a "general" solution to each type of problem has been formed, that is, the correct mindset, and it will be easy to solve this type of problem; At the same time, I have mastered more thinking methods and laid a certain foundation for doing comprehensive questions.

.Prepare all your exam supplies: admission ticket, student ID, black pen, 2B pencil, eraser, ruler, drinking water, etc.

2.Decide how to get to the test center in advance, and if you take the bus, check the route and time in advance to avoid being late.

3.Briefly review what you have learned, you can simply take a look at the past past questions, but don't do the questions again to avoid being nervous.

I'm going to have an exam tomorrow morning
