I, go to the parent-teacher meeting for my eldest niece!

After yesterday’s results came out, Principal Chu Yunxiao convened a meeting with all the outstanding class teachers and teachers in the third year of high school, the purpose of which was to study the third (16th) class of high school.

The senior (16) class is undoubtedly the biggest dark horse in this mock exam, how black is this batch of dark horses? Actually rushed into the sprint class with the worst class in the whole school, if it weren’t for a lagging average score, this group of dark horses would have been able to kill two sprint classes.

Although Wang Yi did the math paper of this mock exam, which gave the whole class full marks in mathematics, the students in the third (16th) class of high school also improved significantly in other subjects.

Originally, Li Comprehensive could only take the test with 20 points, but now he can actually take the test with about 200 points.

The original English test scored 0, but now it is about 60.

Although the original Chinese score of the third (16) class of high school was okay, the average score of the Chinese language in this exam still increased by more than 20 points.

Especially the first Qianqian in the class this time, that is a famous Lai.

The last exam scored 151 points, which completely gave up on herself, except for those who missed the exam, she was the lowest.

But this simulation actually improved by leaps and bounds, and it was unbelievable that I took the first place in the test.

There is only one reason why the third (16th) class of high school has changed so drastically, and that is that my uncle Wang Yi is lecturing everyone.

Less than a week after lecturing, he rushed into the sprint class with the last class in the school, and this Wang Yi’s teaching ability is simply against the sky.

That day, Wang Yi took the senior (16th) class on the lawn and shouted “rush into the sprint class”, and Chu Yunxiao thought that they were going to do the group fight.

It was not until the moment the results came out that Chu Yunxiao reacted, it turned out that they were going to rush the results into the sprint class.

The old fox Chu Yunxiao, who has always been good at picking up treasures, picked up another treasure this time, that is, Wang Yi’s teaching ability.

Wang Yi’s teaching ability is so strong, how can he not catch it? So I brought the best teachers from the third year of high school to the third (16) class of high school.

Wang Yi didn’t feel anything, one more person should be one more sheep.

A sheep is put, a flock of sheep is also put, it doesn’t matter.

The students don’t care, everyone is listening intently to Wang Yi’s lectures, who will pay attention to these big guys?

The most uncomfortable are the garbage teachers who drink tea, sip melon seeds, and listen to crosstalk.

So many bigwigs came to listen to the class, how dare they drink tea and suck melon seeds?

Chu Yunxiao carried the bench to the honest math teacher and sat down.

The math teacher immediately sat down, did not dare to move, trembled all over, and sweated non-stop on his forehead.

“Oh, and melon seeds? Give me two! ”

The math teacher is not giving it, not giving it is not, and he is anxious to wipe his sweat.

“Are you that hot?”

“The main thing is that there are many people!”

“Do you think we shouldn’t come?”

“No, no, no, that’s not what I mean!”

“You haven’t given me melon seeds yet, so give it!”

After everyone was seated, Wang Yi turned on the projector, clicked on the teaching PPT he designed, and began to lecture.

This lesson is a math class, and Wang Yi pointed to a real college entrance examination question: “This question, the answer comes out at a glance!” ”

“Minus 1!”

The class answered in unison.

Li Lingang is a math teacher, and when he heard Wang Yi say “the answer comes out at a glance”, he still didn’t believe it.

He has to calculate this question, he can’t come up with the answer at a glance, how can these scumbags of the third (16th) class of high school come up with the answer at a glance?

However, when Li Lin just heard the whole class shouting “1” in unison, the whole person was stunned, can this really give the answer at a glance?

Hooded, must be blinded, or rehearsed in advance, the purpose is to deceive everyone.

Wang Yi continued the class.

“This question, the answer at a glance!”

“24！”

“This question, the answer at a glance!”

“Pick C!”

“This question, the answer at a glance!”

“Pick A!”

……

Wang Yi came up with questions above, and the learners came up with answers in seconds below.

Li Lingang did not believe in this evil, and desperately calculated with his head, but he was tired of his head without calculating a few ways.

But the answer is exactly the same as the students.

“Little prodigy teacher, please wait a minute, I want to ask a question!”

Li Lingang raised his hand awkwardly.

“What’s the problem?”

“How do the students come up with the answer in seconds?”

This is not only Li Lingang’s doubts, but also the doubts of these new teachers.

Although the principal Chu Yunxiao was also very puzzled, he was more surprised, he was able to answer the questions so quickly, if this set of skills is learned, it will save a lot of time to do the questions.

With enough time, everyone will be able to get better results.

“Big niece, tell him about it!”

Wang Yi didn’t bother to talk about it, this kind of simple question, let Zhang Qianqian talk about it.

“This question, decimal value fill-in-the-blank question, is either plus or minus 1 or 0, and the stem has been analyzed to be less than 0, then it must be negative 1.”

“In this question, there is a correlation value of 5 and 13, no need to ask, the answer must be the relevant value of 12, the question stem can calculate 10 and 26, no need to ask, the answer must be 24.”

“This question, there are 5, 7, 25, 49 in the four options, 5 and 7 appear in the stem, no need to ask, the answer must be related to the square of the two, you can directly exclude A and B, choose one of C and D, the total amount in the stem is reduced, so choose C instead of D.”

Zhang Qianqian talked endlessly to Li Lingang about the problem-solving skills of these college entrance examination real questions.

Li Lingang was dumbfounded, these new people are dumbfounded, this is a real question for the college entrance examination, paralyzed, is the solution so casual?

The teachers who have been listening to Wang Yi’s lectures are particularly calm, this is just Wang Yi’s appetizer, the good show is still to come.

After Zhang Qianqian finished speaking, Wang Yi continued the class: “Let’s take a look at this question!” ”

——

Three girls and five boys lined up

(1) If girls have to be all lined up, how many different ways can there be?

(2) If girls have to be separated, how many different arrangements can there be?

(3) If girls cannot be excluded at either end, how many different ways can there be?

(4) If girls cannot be lined up at both ends, how many different arrangements can there be?

“Let’s fantasize that if three girls and five boys take a plane to travel, the plane crashes and falls on a desert island…”
