Why are 3rd grade math problems so difficult? What is Olympiad Mathematics?

Why are the third grade math questions so difficult now, and what is the Olympiad.

This? <>

Mainly because the questions are becoming more and more flexible now, and the questions for elementary school students have become more difficult, so it is still quite difficult to do.

1. There are various types of questions.

Now there are still a lot of topics in primary school, so in the face of such many topics, children are dumbfounded, the classroom is talking about basic topics, if there is not a good extension, it is difficult to do, so not only children have a headache, parents will also feel a headache, in the face of many topics, in fact, the knowledge point examination is very simple, but the changeable way is unpredictable, especially the primary school students themselves are not strong in brain thinking, there is no good thinking mode.

There is no such thing as a good way to learn.

It will be difficult to achieve the desired effect. In addition, parents usually don't know how to do it themselves, and children will only look at the answers when they encounter problems, resulting in many problems even if they are made, there is no effect, so this is a headache, a topic, really to understand, must be solved step by step, just looking at the answer is not enough.

Second, there are a lot of turns.

Nowadays, primary school topics are also required to be used lively, and generally there are a lot of turns, and the children are dizzy, and they don't know what the questions are going to be, so it is difficult for children to understand and grasp the questions. Mathematics itself is difficult to understand very thoroughly, but its answers are very objective, so parents should usually exercise their children's thinking skills.

Keep practicing, keep intensifying.

Elementary School Mathematics. There are also Olympiad questions, Olympiad questions are really difficult, not to mention, if the foundation can not be mastered, Olympiad is difficult to make, because Olympiad is mixed with a lot of extracurricular knowledge points, although it is mathematics, and general mathematics is different, it has the color and mode of the brain meridian sharp turn, which makes people very confused, and it seems that it cannot be solved with ordinary people's thinking, but if you know Olympiad mathematics, it means that your thinking is very agile, but you can't say that your basic mathematics.

It's going to be good.

Because the foundation is not good, it may be that the method of solving the problem is wrong, or it may be that the logical thinking ability is lacking, so I feel that the problem is difficult. It's the Mathematical Olympiad.

Because the third grade students have already understood the logic of thinking and the method of learning mathematics; Olympiad mathematics is a mathematics that is more difficult and has flexible ways to solve problems.

It may be because education is becoming more and more involuted now, and the Olympiad should be a more difficult version of mathematics, and it is generally a great test of thinking ability.

Elementary schoolOlympiad MathematicsIt can be so difficult that even college students can't do it.

There is nothing difficult about the Olympiad in primary school, but there are some things that involve some professional mathematics knowledge that non-mathematics majors may not be able to learn.

Elementary Number Theory. Needless to say, let's say the one-stroke problem that you came into contact with in elementary school.

In fact, it is the Euler diagram of the theory of enlightenment and defeat.

Elementary school students can get a basic idea of what is going on, but to really understand it, you have to go to university to specialize in graph theory.

Improve Mathematical Thinking:

1. Start from actual needs.

For example, when a family member goes grocery shopping, which way to get to their destination faster and what methods can be used to save money? These practical lives are very helpful for children to think, and for children to understand, often mathematical thinking is formed unconsciously, which is very helpful.

2. Start from the breakthrough.

For example, equations, solving a certain problem feels very cumbersome, using equations will be very simple, when you encounter some problems that are difficult to solve Hail Locust, you will always need to find a breakthrough, such as reverse thinking.

The process of these breakthroughs is itself a mathematical thinking.

3. Start from actual cases.

There are a lot of practical typical cases, these cases are in our textbooks, use these cases, see how the books are analyzed, even if the child can't do it independently, the memorization itself is beneficial, but unfortunately many people will only say that they are helpless, resulting in more and more deterioration.

4. Combine logical thinking.

Training. Logical thinking is well understood. In fact, mathematical thinking is itself a logical thinking, and the two complement each other.

You can buy some books, or related logic training tools, and summarize the benefits of logic to us, etc., and use these to guide the way of thinking in mathematics.

5. Use the tactics of the sea of questions.

There are disadvantages in the tactics of the sea of questions, and of course, there are also incomparable advantages. Children gradually find out some truths and even mindsets from the questions.

It's all mathematical thinking. When the mindset accumulates to a certain extent, the child will naturally break away and form a unique way of thinking.

Don't ask about the Olympiad.

Is it necessary to learn, ask your child if he likes the Olympiad.

In all fairness, learning the Olympiad is definitely a great help for further education, but forcing your children to learn the Olympiad is two words - death.

Parents, first of all, we must have an awareness, children are not sensible, can realize the importance of learning in the first and second years of high school, are considered to be early enlightenment, I was only in the third year of high school to realize that the years are late, can no longer wave. How to guide children to learn Olympiad mathematics? This statement seems too utilitarian, in other words, how to guide children to think diligently?

The Olympiad itself is a competition of thinking, the good vote of the Olympiad children, thinking is very active, get a problem, begin to think about how to solve it from various angles, and the topic of the Olympiad is precisely the need for children to think more or crookedly, as long as the child develops the habit of diligent thinking, it is much easier to deceive him into the Olympiad of no return.

I always remember the Olympiad teacher in elementary school, a super funny old man, I was deceived from the chess club, and the classmates came from the model airplane group, the animal model group, and the group that made nests for cats and dogs. These interest groups will face a variety of problems, such as measuring the situation in chess, how to adjust the center of gravity of model aircraft, controlling the proportion of models, and making litters for cats and dogs to have the concept of plane-space, which seems to be unrelated to the Olympiad of mathematics, but in fact, it has exercised children's thinking skills.

He can get pleasure from thinking and practicing, and this attitude towards learning is very correct, and then a group of us became addicted to Olympiad mathematics and couldn't extricate ourselves.

To sum up, I think parents should not be in a hurry to register their children for classes first, spend more time cultivating their children's interests, accompany their children to play chess, and make model airplanes with their children, etc., so that they know that thinking is a happy thing, which is much more gentle and effective than yelling at their children to instill knowledge.

There is no question of whether or not to learn. The reason why people have to learn, to put it bluntly, is mainly to survive. And the more knowledge and skills you have for a certain person, the easier it will be for you to find a career that you love.

You may feel that the Olympiad is not very useful in life, in fact, any knowledge may not be useful when studying. In other words, in a person's life, a lot of the knowledge they know may not necessarily be used in real life. But you have to remember that if we don't know anything and really need to use it, what do you use it for?

Therefore, no matter what knowledge should be learned, no matter when, we must insist on learning. Only then will you be able to have knowledge or skills that you will be able to use when you need them in the future.

Step 1 Fill 9 liters to a full capacity.

Step 2 Pour 9 liters into a 4 liter bucket, and the remaining 5 liters.

Step 3 Pour out 4 litres of water, pour 5 litres of 9 litres bucket into a 4-litre bucket, and leave 1 litre.

Step 4 Pour 4 litres of water again, pour 1 litre of 9 litre buckets into 4 litre buckets.

Step 5 Re-focus on the closure of Daxin and fill 9 liters of state inspection.

Step 6 Pour 9 litres into a 4 litre bucketThe remaining 6 litres (this is due to the 1 litre of water on the vertical side of the 4-litre barrel).

Calculation formula: 9 2-4 3=6

Many students in the third grade of primary school may have already started to study the Olympiad, but not everyone has the opportunity or ability to study in depth. Normally, students need to have a certain mathematical foundation and logical thinking ability to better understand and apply the knowledge of Olympiad mathematics.

Learn the basics of mathematics: First of all, you need to master the basic knowledge of primary mathematics, such as basic operations and concepts such as addition, subtraction, multiplication and division, decimals, as well as logical thinking and graphic cognitive skills.

It should be noted that learning Olympiad requires patience and perseverance, and it is necessary to choose the appropriate learning method and content according to your actual situation and ability. At the same time, we should not overemphasize the sensitivity of grades and competition, but should pay attention to cultivating students' mathematical thinking and innovation ability.

1. [Test Question] Shouheng stacked 7 identical books, 42 mm high. If you stack 28 of these books, how many millimeters high? (Answered in a different way).

2. [Test Question] A pile of coal is transported from the textile factory, and if 1500 kg of coal is burned every day, it can be burned in 6 days. If you burn 1000 kg a day, how many more days can you burn?

3. [Test Question] A tractor plows 40 hectares in 5 hours, at this speed, how many hours does it take to plow 72 hectares?

1. [Detailed explanation].

Method 1:1) How many millimeters per book?

42 7 = 6 (mm).

2) How many millimeters is 28 books high?

6 28 = 168 (mm).

Method 2: 1) How many times is 28 books to 7 books?

2) How many millimeters is 28 books high?

42 4 = 168 (mm).

2. [Detailed explanation] If you want to burn for a few more days, you must first know how much this pile of coal can burn by burning 1,000 kilograms per day; It is required to burn 1,000 kilograms per day, how many days can be burned, and how many kilograms of coal are in total.

1) How many kilograms are there in this pile of coal?

1500 6 = 9000 (kg).

2) How many days can it be burned?

9000 1000 = 9 (days).

3) How many more days can I burn it?

9-6=3 (days).

3. [Detailed explanation] How many hours does it take to plough 72 hectares of land, so we have to find out how many hectares of land per hour this tractor has?

1) How many hectares of land is cultivated per hour?

40 5 = 8 (hectares).

2) How many hours does it take?

72 8 = 9 (hours).

A: It takes 9 hours to plough 72 hectares.

As a math teacher who has been teaching for more than 20 years, I can tell you unambiguously that except for a few who are not talented or intellectually unable to keep up, in every way, I feel the need to learn Olympiad mathematics.

1.Learning Olympiad mathematics is the training of thinking and the expansion of learning methods. There are many exercises in the book, such as various thinking problems, finding patterns, math wide angles, etc., and Bi Xianmao can be said to be a simple version of similar Olympiad problems.

However, these topics do not form a system, and the special Olympiad is a systematic study, which can promote the further learning of book knowledge.

2.Mathematics focuses on logical thinking, and Olympiad is the best way to exercise logical thinking and methods. Don't worry about the difficulty of the Olympiad, as long as the child is systematically learning the Olympiad, the exercises are from easy to difficult, from simple to complex, so don't wait.

Fourth, fifth, or even sixth grades, it is too late to remember to go to school, and it may feel a little abrupt and difficult to suddenly come into contact with children, and the third grade is a good time to start learning Olympiad mathematics.

3.From the perspective of exam-oriented education, you should also learn a little Olympiad. Take this year's city's primary school graduation and junior high school placement exam questions as an example, the thinking questions in it have a score of more than a dozen points, mainly distributed in the fill-in-the-blank questions, multiple choice questions and application questions, although the proportion is not very high, but if you want to stand out, the ten points are the key to the key.

Of course, if the child is not interested and unwilling to learn, then don't force him to learn, even if he is forced to go, it is estimated that he is absent-minded and passable, after all, interest is the best teacher. It would be best if the training class had a trial class, and you could let the child try it first, in case he liked it again after learning it?

However, if parents have the time and the ability to teach, they do not necessarily have to go to an outside training class to learn, they can buy some relevant books and tutor themselves. The textbook recommends choosing those that are not so difficult, is it too big, don't talk about children, I guess parents will give up first when they see it for themselves.

It's not too late, it's just the right time.

Elementary school students generally from.

It is only in the third and fourth grades that Sun Ji, who begins to have a certain strength of his thinking ability, and his cognition of things and facts begins to slowly become more complex.

If you learn the Olympiad too early, you will often get the opposite result.

Learning Olympiad mathematics is not to start from the grade level, but according to the child's interest and hobby in mathematics, if the child does not like not force the child to learn the Olympiad, there are also a considerable number of children with good academic performance, but because of mathematical thinking methods, mathematical thinking and other reasons, at the beginning of the interest, but after contact with the Olympiad is also normal to have a fear of difficulties. Parents should remember: twisted melons are not sweet.

Don't force your child.

In addition, it is best to learn Olympiad mathematics from the first grade, and it is too late to wait for three years, unless the child is particularly smart and the object is particularly inspired.

I am a teacher who has studied Olympiad mathematics.

Hope it helps!

In the second grade, the foundation is built, but the pressure must be gradual.

Today's children are so stressed! To be honest, in the six years of primary school, the six years of middle school and high school, I have used addition, subtraction, multiplication and division in the mathematics I have learned, from the time I graduated from college to the present.

On the contrary, the painting and piano I learned before are very useful, at least, they can help me relieve stress and relieve fatigue when I am stressed.

What are the benefits of starting the Olympiad in the third grade.

Whether learning Olympiad mathematics is good or bad depends on the situation of the individual learner. If students who study Olympiad mathematics are more interested in logical thinking training itself, and also have a certain foundation, they will feel like a tiger with wings and a fish in water, and basically there will be no harm.

It's not too late, my sister studied in the first semester of the sixth grade, so it's not good now! As long as you study hard, you are not afraid of being too late.

If the child is interested, it will be fine from the first grade, but at least after addition, subtraction, multiplication and division, the Olympiad exercises the mind, which is very good.

Olympiad mathematics is not a new subject, but a relatively difficult mathematics, and doing more Olympiad mathematics, or mathematics can expand ideas, and even practice to see problems from different angles, is a very good thinking training. So it's certainly not too late, but if the goal is to get a ranking, it depends on the foundation of each person, maybe it's not too late, maybe you need more training.

Learning Olympiad mathematics is actually training thinking, no matter when it is not too late, but this thing actually depends on talent, and it is only applicable to some people, so for some people, it is too late to be born. After all, some people's specialty is not that. Therefore, it is recommended to analyze the specific situation on a case-by-case basis and follow the interest.
