After returning home, Principal Hu called Lu Gang: "Old Lu, that *** is also new here and doesn't understand the rules. There's nothing wrong with your Lu Long, so forget it this time."
Listening to Lao Hu's lonely tone, Lu Gang guessed where he might have been defeated. Many people are like wild dogs sometimes. When there is no benefit, they are as fierce as wolves. When there is benefit, they wag their tails like rabbits.
He was still docile. Principal Hu was also a unruly teacher in the school when he was not the principal, but after becoming the principal, he was afraid of this and other ways to please his superiors, so Lu Gang did not want to embarrass him and said: "Don't you
Forget it if it’s convenient, I understand, I’ll handle it myself.”
Principal Hu didn't say anything and hung up the phone silently. He felt very sad, and at the same time he was thinking: Li Xiao, you bitch, don't fall into my hands. When the time comes, I will justifiably beat you to death! This grudge is recorded.
At the same time, Lu Gang was also thinking about how to fix this stupid young man from out of town.
During class on Wednesday, Lu Long did not come to class. Thinking of what happened yesterday, Li Xiao didn’t pay much attention. *** The humorous classroom atmosphere brought the children closer, and children of such an age were generally carefree.
The classroom atmosphere was very active because of the grudge. The students temporarily forgot that the humorous teacher in front of them had kicked their classmates away and knocked them unconscious yesterday. When discussing the problem, the two students started arguing, and their voices became louder and louder.
One said: "It's a loss of 100 yuan, you idiot!" The other said: "It's only a loss of 50 yuan, you're a brainiac! I can't explain it to you, a retarded person!" The other students heard the noise here.
Loudly, everyone stopped discussing the problem and looked at them.
"What are you arguing about?" Li Xiao asked kindly.
Seeing that *** was not angry, one of the classmates stood up boldly and said: "Teacher, we are discussing an interview question about someone with an annual salary of one million!"
"Oh? It's so awesome. Let the classmates listen to it." The other students became interested when they heard the words "annual salary of one million". A few of them even urged him to speak quickly.
"The question is like this. Xiaomi went to the store to help sell shoes. A pair of shoes cost 15 yuan and the selling price was 21 yuan. A customer bought shoes for 50 yuan. Xiaomi had no change and asked Boss Wang next door to exchange them.
He gave the customer twenty-nine yuan in change of fifty yuan. Later, Boss Wang found out that the fifty yuan was fake money, so Xiaomi returned the fifty yuan to him and asked how much money Xiaomi had lost."
"I've seen this topic before." "I've seen it too."...Many students rushed to speak.
"Haha, students, be quiet for a moment and let's discuss this issue together. Let's first ask the student who asked the topic to share his views."
"Teacher, I think he lost a hundred yuan because he took fifty yuan in fake money and gave Boss Wang another fifty yuan, making a total of one hundred yuan." The student said.
"Bragging! He gave Boss Wang the fifty yuan of fake money given by the customer, and Boss Wang gave him fifty yuan of real money. Later, he returned fifty yuan to Boss Wang, so he only lost fifty yuan."
"What you said is wrong. He lost 15 yuan for shoes and 29 yuan from customers, which is a total of 44 yuan. He also lost another 50 yuan from Boss Wang, so Xiaomi lost a total of 94 yuan.
Yuan, you are talking about how much money you lost." Another classmate said unconvinced.
"You are all big shaobings! Xiaomi asked a customer for 29 yuan in real money, and the customer gave him 50 yuan in fake money. He lost a total of 79 yuan. You can't figure out such a simple problem!"
"What you said is wrong. He made a profit of six yuan by selling fifteen's shoes for twenty-one yuan, so the loss should be subtracted from the profit. He only lost seventy-three yuan."
"Take fifty fake money and give fifty to Boss Wang. Losing one hundred is just a must!" One student stood up and said, his tone of voice imitating the tone in the sketch, which made the whole class laugh.
Li Xiao did not interrupt their argument. He believed that such arguments could improve students' ability to think and solve problems.
"Ninety-four, absolutely!"
"Fifty no explanation!"
…………
Seeing that the students were almost finished arguing, Li Xiao asked: "Does any other student have any other answers?" The classroom became quiet, and a girl stood up and replied: "Teacher, I think Xiaomi lost 44 yuan.
There was no loss from Boss Wang, only fifteen yuan for shoes and twenty-nine yuan for replacement, a total loss of forty-four yuan."
"Then the shoes can be sold for 21 yuan, so how can you only count it for 15 yuan? It means the actual loss, and the profit part is also considered a loss, so it is a loss of 50 yuan!"
"Teacher, I don't agree! I insist that the answer is ninety-four yuan. Mine must be right! You idiots!" a student said proudly. What he said made other students dissatisfied. Many people yelled and scolded him, "You are stupid."
You’re the one who’s mentally retarded!” “You’re just stupid!” “You’re not even mentally retarded, you’re a coelenterate without a brain!”… These primary school students are easily excited. In order to show that they are smarter than others, they sometimes fight each other with their stubborn opinions.
It's also normal.
If other teachers hear students scolding each other, that's fine. Some students may have to take political classes, but our teacher believes that this is the true expression of students. It is a good thing to dare to express their different ideas, as long as they are done correctly.
Just guide.
Li Xiao smiled and said: "Everyone, be quiet. Now the teacher is here to solve this problem with you. Your answers are one hundred, fifty, ninety-four, seventy-three, seventy-nine, and forty-four."
Is there a different answer?"
"No more!" most students replied.
"Then let's go step by step. First, Boss Wang gave Xiaomi 50 yuan, and then Xiaomi paid him back 50 yuan. In this process, neither Xiaomi nor Boss Wang made a loss or made a profit?"
"Yes." The students answered in unison.
"Xiaomi gave the customer a pair of shoes and 29 yuan. The total is 44 yuan. Think about it, is that true?" Li Xiao felt that it was incredible that students could not understand such a simple question.
The students were thinking and no one answered.
Suddenly a boy stood up and said: "Teacher, shoes should be sold for 21 yuan. If you add 29 yuan, it should be 50 yuan. If you don't count the profit, it will be 44 yuan. So there should be two answers."
One, fifty and forty-four, right?”
"My dear friend, it's great that you are diligent in using your brain! But the teacher prefers one answer, which is fifty." Li Xiao wrote fifty on the blackboard. "In general, it's just one answer."
Situation, you were deceived by someone using fifty yuan of fake money, and you were given something worth fifty yuan for nothing, so naturally you lost fifty yuan." Li Xiao paused, and then said: "Students, think about it.
"
"Yes," a student discussed in a low voice with his deskmate, "You can't just count the purchase price of the shoes. The value of the shoes when they are brought to the store is 21 yuan."
"If you accept fifty fake money, you will lose fifty!" The classmate who just answered fifty said proudly. "It took me a long time to answer such a simple question. What a loss."
The students were thinking or discussing, and seemed to understand something, but it was not so clear.
When class was about to end, a tall boy in the back row stood up and asked, ***, let me ask you a question: "There are two men and two women with different STDs, and there are only two condoms. How can I use condoms to have sex separately without getting pregnant?"
What about mutual infection?”
Li Xiao was so shocked that he almost rolled off the stage. Several girls blushed, and more students looked at him strangely without knowing why.
"Um... you come to the office after class and the teacher will tell you." Li Xiao sighed, the Internet is such a double-edged sword, I am really speechless. It seems like I have to go down and do some ideological work on this student.
