Li Siyuan took great pains and began tutoring for the Mathematical Olympiad

[Congratulations to the host, the number of shock points can be drawn in a lottery, and the system will automatically win the lottery. ]

[Congratulations to the host, you have acquired the Mathematical Olympiad tutoring skill and can explain complex Mathematical Olympiad questions in an easy-to-understand manner. 】

Li Siyuan was stunned. Isn’t this an enhanced version of mathematics teaching skills?

Yes, but since I already have this skill, I don’t need the system to give me another one.

[Host, what the system gives is an all-in-one version, and it is the most easy-to-understand version. The original teaching method of the host, with teaching on many topics, is incomprehensible to these primary school students. ]

This time it was rare for the system to say a few more words.

Only then did Li Siyuan realize that the system had been strengthened and perfected for him.

Good, then it will be easier to bring more knowledge to these students.

The busy weekend is over.

Wait until Monday.

The students came to school excitedly again in the morning.

Welcome to a new week of classes.

Starting from this week, Li Siyuan is no longer ready to teach them new knowledge points.

Instead, it was decided to give them a start in consolidating their knowledge.

Because their final exam is coming soon.

If nothing else, this exam must be a county-wide joint exam.

As long as these children can get good grades, it means that their teaching is successful.

The first cultural class is mathematics class.

“Students, there are ten math problems on the blackboard. You can start doing them now.”

Li Siyuan copied the Mathematical Olympiad problems carefully prepared over the weekend on the blackboard.

Question 1: A farm harvested wheat. It was planned that 18 people would harvest it in 6 hours a day and 15 days. Later, in order to speed up the harvest, 9 people were actually added every day, and the working hours increased by 2 hours. The harvest was actually completed a few days earlier than the original plan. A task? (Test the readers, finish it in one minute!)

Question 2: Each item in the following sequence is represented by an array of 3 numbers, which are in order:

(1, 3, 5), (2, 6, 10 ), (3, 9, 15)…Q: What is the sum of the three numbers in the 100th array? (Test all readers, you have a time limit of 30 seconds to complete it!)

…

All the students looked at the question.

I feel like this is different from the questions I have done before?

Generally speaking, it has become difficult.

The questions they did in the past were all the same.

Either multiply or divide, it’s very simple.

Maybe even if you don’t know how to do it, you can still do it by using the test-taking skills taught by Li Siyuan in the past and just multiply and divide.

But the topic now is different.

There is too much data in it, and the amount of information is huge.

It’s really hard to figure out how to do it.

After all, how do you multiply and divide so much data?

In the face of such difficult questions that require certain turns, the original simple test-taking skills directly lose their original effect.

Soon, Li Siyuan had copied all ten questions on the blackboard.

Some of the students in the audience were still looking up, some were biting their pens in deep thought, and some had already started writing furiously on their own draft papers.

Li Siyuan put his hands behind his back and looked around the classroom.

He needs to know what these kids are capable of.

Because ordinary examinations are more about testing students’ basic level.

But in a competitive competition like the Mathematical Olympiad, basic level is of course also indispensable, but it is also a process of selecting the best.

The same goes for these kids right now.

Although everyone’s foundation has been somewhat stable after being reinforced and strengthened during this period of time.

But there is indeed a clear gap in their performance in facing difficult problems.

Some students quickly came up with ideas and solved the difficult problems.

There are also some students who are writing, but what they write is purely blind, or they have wrong ideas from the first step.

Some even have no idea where to start and can only write an answer.

It can only be said that some things cannot be brought back with hard work.

Netizens in the live broadcast room have secretly taken out their scratch paper.

They all started writing on the scratch paper.

“Oh my god, these questions are really difficult. I can only do three of them.” ”

I’m a bachelor’s degree graduate. Why do I still have five questions that I haven’t done yet? It seems that I am in college.” I’m still decadent. I won’t find a girlfriend starting tomorrow.” ”

These questions asked by Li Siyuan should be the knowledge points of the Mathematical Olympiad, right? I feel that we need to use linear equations to solve them. If we can’t use equations, I don’t know how. Done.”

…..

“Dear students.”

After a full twenty minutes, Li Siyuan waited until he had read all the students’ answers.

He coughed slightly and said.

From the students’ reactions, Li Siyuan has seen the difference in everyone’s level.

“Recently, many students may feel that their academic performance is already very good, and they are even a little proud in their hearts.” ”

I feel that students in the county are just like this.”

“Confidence is necessary, but you can’t be conceited. You can’t. I feel like I am invincible.”

This is another reason why Li Siyuan asked these Mathematical Olympiad questions.

Because especially recently, with Li Siyuan’s efforts, students have gradually stepped out of their inferiority zone.

He even vaguely felt that some students were a little impetuous.

From time to time, I can still hear students saying that it is easy to surpass the children in the county.

Encouragement is needed, but so is appropriate suppression.

“So today I will show you the difficult mathematics training that many of the children in the county are participating in.” “How do you

feel after doing it? Do you find it difficult?”

Many students in the class nodded. Agree.

“But you have to know that there are many good people in the county who can answer all these questions correctly.” “What you want to compare

is not only the 80% of the basic students, but also the 80% Twenty top students.”

“I want to ask, do you want to go to a better school, or is it enough to go to an ordinary school?”

Li Siyuan asked.

All the students in the audience straightened up: “Of course I want to go to a better school.” ”

That’s right, I have been studying like this for several years. If I can go to a better school, I will naturally go to a better place.”

After hearing this , Everyone’s ambition.

Li Siyuan nodded: “Yes, each of us wants to go to a better school, so we must know the rules of the exam.” ”

All exams have about 70% basic questions. This % 70. Once you master it, you will have no problem getting into an ordinary university.” ”

But if you want to go to a good university, you need to get more points from the remaining 30% of the advanced questions. .”

“And the difficulty of these 30% questions is about the difficulty of this kind of question.”

All the students immediately felt a hint of nervousness.

Especially those students who saw that they had only solved a few questions were so nervous that they began to bite their own pens.

“So starting from today, I will give you a reinforcement course. I hope you will listen well and learn well.” “If you find it difficult

for the moment, don’t worry if you think you can’t.” ”

The role of a teacher is to let you You have never been able to become able, and I believe that under my guidance, your progress will be very fast.”

Li Siyuan’s words can be said to be painstaking.

Don’t let them be proud, and don’t let them be frightened by these problems.

Hey, it’s like having an extremely sensitive girlfriend.

If you don’t talk, others will do it. If you talk more, they will break up.

Hard to bear.

Just when Li Siyuan was preparing to draw the lottery.

In an office of the County Education Bureau.

There is a meeting going on about this final exam.
