Nima!!

Just let people solve the problem by dictation? Don't play like this, math teacher, you're starting to play so high-end now?

Even if you ask us to mentally calculate the addition, subtraction, multiplication and division of two digits, we may not be able to answer this question in the first time......

Will play.

Have you started playing this routine in high school math?

Zheng Yihang smiled slightly, he didn't plan to say anything about the content of the books in this first class, these students were able to be admitted to the first middle school in the city, which in itself shows that their IQ is not low, and the content of the books will be able to be thoroughly understood sooner or later, now it is just to mention their interest.

Mathematics, if you are not interested in it, what is the difference between taking a math class and chewing wax?

A real math class should be immersed in it, and it is only ...... that you have fun with math

Five seconds later, Zheng Yihang said, "Now please raise your hand if you know the answer." ”

In such a hurry? In such a hurry?

"No one, right? No one should be able to answer this question......"

"It's too hard."

"I won't...... It's a difficult question......"

Brush! Brush! Brush!

But the next moment, the three of them raised their hands again.

Fang Chao's face was shocked, and someone raised their hands two seconds faster than him......

City No. 1 Middle School is indeed the land of Crouching Tiger, Hidden Dragon, with the strength level of the first CMO mathematics in his province and region, it is still only third.

"What's your name to the bespectacled boy at table six in the third row?"

"Yang Ning."

Yang Ning opened his mouth to speak, he also wore a pair of glasses, judging by the degree of about five hundred degrees, his body was slightly fat, one meter seventy-one, and his weight should be about one hundred and forty pounds.

The students at this age are too sports-oriented, and the weight of ordinary elementary school students is very scary.

"Yang Ning, is it? Come, tell me your answer. ”

"2012."

When Yang Ning replied that it was 2012, Fang Chao and another classmate suddenly beat their chests, a few seconds late, and were forced to be pretended by others.

Zheng Yihang smiled and said, "Yes, very good, the answer is correct, Yang Ning, you can sit down first." ”

Yang Ning took a seat.

At this point, the atmosphere of the class is a little different.

Who would have thought that in this class, there are so many Crouching Tiger, Hidden Dragons like dogs.

So much so that in the future, people in other classes will see those who are learning mathematics, but all the mathematical geniuses in class 7 are absolutely dogs to death, they are too capable of pretending to be forced, and they can't compare mathematics with people in class 7, especially there is a dog king in class 7, which is simply the best.

But soon, Zheng Yihang said with a smile again, "After playing two questions, then we won't be so serious, I'll make a puzzle question, you will solve it?" ”

"Isn't it, Teacher Zheng, still coming?"

"Teacher Zheng, if you ask the question again, we will really have to doubt our IQ."

"We all entered the city No. 1 middle school with excellent results in the high school entrance examination, but this was only the first day of school, and I wondered if I was in the wrong class...... In the future, I will be afraid of math, Mr. Zheng. ”

"Yes, Mr. Zheng, don't challenge our intelligence."

Zheng Yihang said with a smile, "Just now it was indeed a test of your basic skills and reaction ability, but this time it is really a very simple puzzle question, which is a question that middle school students will have." ”

"Really?"

"Then Mr. Zheng, you can make the question."

"Okay, we've already been humiliated once anyway, and don't mind being humiliated again."

Zheng Yihang walked among the classmates, and then began to say, "You are all excellent students carefully selected from various middle schools to enter the City No. 1 Middle School, and I should be a good teacher, but you seem to have a little opinion about me. ”

"Teacher Zheng, we have no problem with you."

"Teacher Zheng, don't talk nonsense, we all respect teachers...... You suddenly say that we have an opinion about you, isn't that a cheat. ”

"Shh

Zheng Yihang made a silent gesture.

After all, Fu Lingyan used to be the class leader, and at this time she said, "Everyone is quiet, Mr. Zheng is caught in the situation, he is giving us questions." ”

"Ah, I see."

"Got it."

At this time, Zheng Yihang continued, "Because you have opinions about me, I, a new teacher who has just graduated for a few years, is a little trembling, afraid that you will make some small actions when I am in class, disobedient, and even ignore my math class, as your math teacher, I can't let such a thing happen, in order to maintain the friendship between me and you, I went to KTV to open a big box, and invited all the students to sing loudly, But the premise is that every student who goes must bring a hat, and the color of the hat must be black and white, of course, in this party, black and white hats must be there. ”

Zheng Yihang's short words have obviously brought the students into the situation he set up, and for a while, everyone seemed to have come to KTV, this is a hat feast, very interesting, and they are even looking forward to such a party to liven up the atmosphere.

Some of the students have already captured some important information points from this scene.

Teacher Zheng is a very amazing person, obviously not very old, but the way he plays in the tricks is a little unexpected, Fang Chao likes such a surprise.

It's funny.

Originally, I thought that young teachers were not as good as old teachers, but old teachers are better than qualifications, and new teachers are better than no constraints, and there is a new set of teaching methods.

"I'll prepare twenty more black and white hats myself, and then I'll put them all away, turn off the lights, and you'll each pick one hat to put on your head."

"And so our hat-trick began."

"Notice, after each of you chooses a hat, you can see what color the hat is on the top of the other people's heads, but there is no way to see what the hat is on your own."

"So now, I'm going to have people turn off the lights, and if someone thinks they're wearing a black hat, they're going to slap themselves, and the first time, there's no sound of the slap, so I'm going to turn on the lights and let everyone see them again, and then I'm going to turn off the lights again, and this time, there's still no sound of slaps, what's going on? I've obviously asked people to prepare black hats, and some of you do wear black hats, I don't believe in evil, turn off the lights for the third time, this time, hehe, finally someone slapped himself, papapa, I didn't expect that there were really masochists, and I like to beat myself......"

The students were snickering.

Mr. Zheng, you're too funny, aren't you?

Do you really teach math and not cross talk? How can it be so cute?

But the next moment, Zheng Yihang asked, "Now, the question is, how many of our classmates wear black hats?" ”
