The post-00 principal took over, and students all over the network went crazy

Chapter 276 Chapter 276: If you don’t know common sense, you will suffer a loss
Hearing the laughter of his classmates, Su Jing frowned: "Quiet."

"Students who know, don't laugh."

Then he said to the standing classmates: "Sit down first."

The male classmate sat down awkwardly.

Su Jing signaled other students to put down their hands and answered: "One kilogram is equal to two catties, and one catty is equal to five hundred grams."

"There's nothing funny about this, no one is an encyclopedia."

"Students who know, listen modestly, students who don't know, just listen attentively."

After briefly educating those students who were making fun of others, Su Jing continued: "Now that everyone knows that a pound is [-] grams."

"Then do you know how much a pound weighs in your hand?"

"And different vegetables, how much is a pound?"

Two questions in succession confused the students.

Just when they were at a loss, the canteen staff brought several bags of different dishes.

There are potatoes, vegetables, pork, tofu soaked in oil and a bottle of mineral water.

Auntie put five kinds of things on the podium table and left.

Half of the podium table was made into a lifting platform, and Su Jing placed the dishes one by one on the lifting platform.

"Here, there are five different kinds of dishes."

"Everyone might as well discuss what you think is the amount of one pound."

"I'll invite two classmates who often go shopping with their parents to come up and experience it later."

The lift platform rises to make it easier for students behind to see the weight.

The students instantly fell into an argument.

Their discussions were all different. Some students felt that although there were only two potatoes, considering the weight, they should be almost a pound.

Some students looked at the big bag of green vegetables and thought that the leaves were light, maybe only a pound; but considering that the stems accounted for the weight, they felt that it must be more than a pound.

There is also the small piece of pork, a large bag of tofu soaked in oil and the [-] ml bottle of mineral water.

Before the kilograms and grams were digested, another milliliter of water came.

For a while, the students who knew were relieved, while the students who didn't knew were even more troubled.

Two minutes later, Su Jing said: "Okay, are there any classmates who often buy groceries who can volunteer?"

Seeing that many students still raised their hands, Su Jing randomly named two students to come up.

One male classmate and one female classmate.

They weighed the five vegetables one by one with their hands.

They cannot compare songs one by one, they try one by one.

The male student finished it first and said: "I think potatoes and meat are closer to one pound."

The female classmate also finished weighing it and said, "I feel like everything except water should weigh one pound."

Su Jing asked the female classmate: "Why is water not a pound?"

The female classmate replied: "It says on the bottle that the water is [-] milliliters."

"But I remember, five hundred milliliters of water seems to be half a catty."

The students in the audience were a little surprised: "What? Can milliliters and kilograms be converted?"

"Isn't it? Can tens of thousands of units be converted?"

"..."

They expressed their shock one by one. Su Jing nodded and motioned for them to go down first.

Su Jing: "Actually, these things weigh one kilogram."

"One pound of water is equal to [-] grams, which is equal to [-] milliliters." "These are students who often go shopping with their parents. If you don't go there often, do you think some bosses will think that you are students and don't understand life? Common sense defrauds you of your money?”

[Yes, yes, don’t think that some bosses outside will be very kind and bully you because you don’t understand. 】

[I went shopping for groceries two days ago and got scammed.Not only is the weight a bummer, the unit price is also a lot higher.The pork was sold to others for [-] kilograms, but when I asked about it, it was only [-] kilograms.If I hadn't heard it over there, I wouldn't have believed my ears. 】

[Some of the names now are ghost names. If you don’t know how to use them, you will suffer a lot.I bought a pound of longan, and when I got home and weighed it, it was only [-] taels. I said it didn’t feel right to carry it. 】

【Seven taels?How many grams is seven taels? 】

Su Jing was a little disappointed with the results of the questions asked before class.

Their math scores cannot be said to be bad, but students who can enter the threshold of No. [-] Middle School can still get a passing grade.

The conversion of single items such as grams, tons, and meters in the textbook can be said to be known without even thinking.

But once it is applied to life, it becomes difficult to calculate the boast.

Su Jing felt a little headache. Wouldn't it be embarrassing if it was broadcast live?
But there is no other way, now that we are here, we can only bite the bullet and continue talking.

Su Jing first talked about the relationship and conversion between various units, and then briefly talked about the approximate price of the current dishes.

Seeing the students writing with paper and pen, he felt helpless: "Everyone will focus on listening in this class."

After all, there are no desks now, so it is really inconvenient for students to write with their legs propped up.

However, the students were afraid that they would not remember it and did not listen to Su Jing's advice at all.

Su Jing shook his head and no longer wasted time caring about them.

I wasted some time just asking questions at the beginning. If I don't seize the time to continue, I'm afraid I won't have time to teach the lessons I prepared.

After finishing a few small points, Su Jing looked at the time.

Seeing that the time was almost up, I found the video I had prepared in advance.

Su Jing: "It's almost time for this class. Let's watch the last video on how to choose dishes."

"I took this photo in the supermarket last night. The types are limited. You can learn these first."

"You can also go back and ask your parents who are shopping for groceries to see if they have any tips, and then share them with your classmates at school."

The students cheered.

You can watch videos again.

Although Su Jing's class is quite interesting, everyone prefers watching rather than listening.

In the video, there is a supermarket in the background, and the rear camera goes straight to the vegetable section.

Then a title appeared: How to choose vegetables in common sense of life?
Su Jing's voice also appeared.

In the vegetable section, Su Jing walked to the first dish, picked up a green cucumber, came close to the camera, and said, "The harder the cucumber is, the more delicious it is."

In the video, in addition to Su Jing's voice, there are also the hands that pick up the cucumbers, with distinct knuckles, which at first glance belong to Su Jing.

[The relationship was filmed by Principal Su himself? 】

[Let me go, Principal Su is a man, but he knows how to choose vegetables? 】

[But this cucumber does taste better the harder it is, I testify. 】

[Grocery shopping for post-00s generation: choose good-looking ones! 】

In the video, Su Jing moved to a nearby storage area.

He first photographed the vegetables in the entire area, then selected a handful of spinach with a distinctive color and said: "The greener the spinach, the more delicious it is."

"Choose radishes that are heavy when weighed."

“Loose organic cauliflower tastes better than compact regular cauliflower.”

"Those with a smooth surface are crispy potatoes, and those that are dark, black and yellow are flour potatoes."

"..."
