Before Lin Chaoxi finished speaking, Pei Zhi had already pushed away the chair and stood up.

He first went to a table at the back, patted one of the students on the shoulder, and said something while lowering his head. The other child subconsciously looked at the pile of books placed in the middle of their table, but because it was Pei Zhi who made the request, it seemed that he could not refuse, so he nodded.

Pei Zhi reached out and picked up a book, began to flip through it, put it down after flipping through it, and then picked up the second one.

He flipped through the pages very quickly, and was basically just flipping through them, so that he could finish flipping through a stack of more than a dozen books in the same amount of time as a normal child would finish a question.

After finishing the books at one table, they moved on to the next one, except for Zhang Liang's group. Soon, Pei Zhi flipped through all the books from other groups, and finally sat back in his original seat and started writing.

Title, author, edition...

Lu Zhihao was very confused. Huajuan probably knew what he was going to see and looked at Lin Chaoxi in shock.

Pei Zhi lowered his head and wrote very seriously. As time passed, chapter names appeared one after another in the exercise book.

——"Counting and Counting" p.3-5

——《Filling in the Map and Dividing the Numbers》p.22-25

——"Interesting Questions about Natural Number Strings" p.35-38.

…

…

"Olympic Mathematics for Fifth Graders" by Pang Tian

——《Decomposition of Prime Numbers and Composite Numbers into Prime Factors》p12-6

…

…

The pages of the exercise book were gradually filled up, and Lu Zhihao's mouth was big enough to fit an egg.

Lin Chaoxi looked at the catalog written by Pei Zhimo and felt a little relieved. Who would have thought that one day, she would have the opportunity to use her little male god as a brain scanner.

Yes, because they don’t have so many reference books, so they first copy down the entries marked with 1 in other people’s catalogs, and then compare them with their own set of teaching materials to find out the omissions and fill in the gaps, which is very fast.

——

Although the method is good and there are powerful scanners that can save them a lot of effort, it is not easy to actually do it. The main problem lies with Lu Zhihao and Huajuan.

Lin Chaoxi suggested that they organize the knowledge points according to a set of textbooks first, and picked out a set of classic textbooks on the bookshelf and asked them to organize them first.

In fact, Lao Lin has mentioned two points about how to choose books. The first is to compare them horizontally. You can know what is good and what is bad by reading each book once. This is a bit of a test of the reader's own quality, which is very abnormal. The second is to choose books with many revisions. If a textbook has been revised and republished repeatedly, it largely reflects the attitude of the editor and its classic level.

But even after choosing the textbooks, the two little students sat together and spent a lot of time just copying the table of contents.

What's more, the more they wrote, the more they fell into mechanical copying. Lu Zhihao and Huajuan were both very serious, but as time went on, the longer it took them to incorporate a new knowledge point into the framework.

Lin Chaoxi's brows furrowed more and more as she sat. In this situation, it would be best if someone could guide her. However, she glanced at her childish reflection in the window and realized that this person definitely couldn't be her.

Pei Zhiguang spent an hour copying down all the chapters marked with "1". Lin Chaoxi took a look at the densely packed chapter names and the content was too much. Of course, she could clearly distinguish which ones were which and which ones should be classified with which ones. But it would take an ordinary primary school student one or two days to analyze all these contents. They simply don't have that much time.

She quickly looked at Pei Zhi apologetically and quietly hid the notebook.

——

Lunch time in the Oasis Base cafeteria.

All the students who seem to be walking unsteadily and reading notebooks in their hands, regardless of their age, must be students participating in the Jinbei Summer Camp.

In Lin Chaoxi's entire senior group, half of the students refused to come out to eat.

Because according to the original plan, the exam was at two o'clock after lunch, everyone was reading and doing exercises desperately to catch up on time, for fear of missing any content.

This included Xiaolu, of course. In the end, Lin Chaoxi and Huajuan Peizhi worked together to force him to come to eat, saying that if he relaxed before the exam and had an empty stomach, he would not be able to pass the exam.

The three little boys were eating outside, and she went to the cafeteria's back kitchen to report and accept punishment.

Lin Chaoxi stood in front of the cafeteria manager. The kitchen was filled with steam and the smell of oil smoke, which was very irritating.

"I've been waiting for you for a long time this morning." The aunt folded her arms and looked at a lazy child.

"I...got up late today." Lin Chaoxi said honestly.

The aunt looked around the kitchen, then looked at her height, smacked her lips, and said in disgust: "What can you do? There is something wrong with teachers nowadays."

Lin Chaoxi almost laughed out loud, thinking that you are really right.

"Go get a quick rag, clean up outside, wipe the table, and collect the dishes that haven't been put away. There are too many people who are not aware of it now."

"Okay!" Lin Chaoxi responded diligently.

——

The difference between working in the kitchen and working in a restaurant is that the latter is a public execution. Fortunately, Lin Chaoxi is very thick-skinned and often helps out in the canteen of the welfare home, so he doesn't care about it at all.

The cafeteria has hundreds of tables, and adults and children eat together. It is bustling with people coming and going.

Among a group of old ladies who were collecting plates and cleaning the table, there was a primary school student who was running very fast.

She held a rag in one hand and cleared the plates with the other. Whenever someone got up to leave, she was always the first to find the stainless steel plates that had not been collected. Relying on her short stature, she was very nimble in moving around and snatched a lot of work from the aunties.

She was so fast that some adults and children's plates on the table were quickly collected before they had even taken two steps. The little girl who collected their plates would even carefully wipe the dirty table clean and smile at them at the end.

This made many adults and children feel very embarrassed, and they turned back and took away the things they should have taken away without waiting for her to take the things away.

Lin Chaoxi passed by Lu Zhihao's table. Little Lu was holding a pencil in his hand and asking Pei Zhi how to solve a problem.

Pei Zhi was eating celery with a fork while reading the questions. He ate very slowly and looked reluctant, but he was still eating. Lin Chaoxi found that no matter what the fixed meal was, Pei Zhi would always finish it carefully, without leaving a grain of rice. No wonder he could grow so tall in the future, Lin Chaoxi thought.

It was a question about finding patterns in numbers. Lu Zhihao applied several formulas but none of them seemed right. He couldn't turn to the book because he didn't have it with him. Pei Zhi never memorized formulas, so he just explained his own thinking. Lu Zhihao's face wrinkled again, so Pei Zhi didn't know what to say, and the celery tasted even more bitter.

Lin Chaoxi went over to take a look and thought this was a great educational opportunity.

"Class monitor, think about it. This question mentions natural numbers and multiples. So which knowledge point and content does it belong to? Think about what you just sorted out."

Lu Zhihao flipped through the notebook and read it for a long time, but still couldn't understand.

"It says here that adding 1 is a multiple of 2, which means this natural number is an odd number. It is also a prime number. 2 and 3 are coprime, right? It must be related to prime numbers..." Lin Chaoxi patiently persuaded.

Lu Zhihao listened for a long time, looked through it for a long time, and finally said: "Write out the solution, I will understand it after reading it."

Lin Chaoxi felt that he had failed.

——

Education is definitely a big problem. She is still a teacher training student. When she really encounters the actual problem of how to teach children, she becomes a little helpless.

How did Old Lin do it so smoothly in the past? Lin Chaoxi thought that either she was gifted, clever, and smart, or her father really put a lot of effort into teaching her this.

At exactly two o'clock in the afternoon, Jie Ran walked into the reading room on time, holding a stack of test papers in his hand.

The desks of all study groups were piled with books and exercise books. Each little head was buried in the books, revealing the dark back of the head and the hands that were constantly writing. The atmosphere of study was thick, comparable to a university library before the final exams.

Teacher Xie Ran was very satisfied. He clapped his hands and said, "Okay, students, let's have a happy exam."

"don't want!"

"Can we take the test later?"

“We haven’t finished yet!”

Protests continued.

Next to Lin Chaoxi, Lu Zhihao was shaking his legs at a very fast frequency, but he was still seizing the time to do the questions.

"Lao Lu, are you in a hurry to pee?" Huajuan asked in a low voice.

"No... don't talk to me. There's one more thing." Lu Zhihao's lips were trembling from holding back his anger.

"Go quickly." Pei Zhi also said.

Seeing this, Lin Chaoxi snatched Lu Zhihao's pen and said, "Hurry up, hurry up, I promise to ask Teacher Xiaojie to postpone the exam."

"real?"

"I promise!" Lin Zhaoxi swore

Hearing this, Xiao Lu stood up and ran out of the reading room without looking back.

"What's going on?" Xie Ran asked with a smile.

Lin Chaoxi stood up and said, "Teacher, can we postpone today's test for a while?"

At the small table in the reading room, all the students looked at her intently.

"No." The answer was very understanding.

Many children were disappointed and depressed and started to pack up.

"Then can those who want to take the exam take it first, and we will take it later. Separate the tables on both sides and you sit in the middle. We promise not to talk to them!" Lin Chaoxi said.

"You will take the exam sooner or later. There is no point in reading a few more hours." Jie Ran advised.

"Please." Lin Chaoxi said decisively, clasping his hands together and bowing.

Xie Ran had never seen anything like this before and was stunned.

However, after she said this, many children got the trick.

"Please."

"Please, teacher."

The children's eyes and voices were so soft, and they tried so hard that even the most heartless people couldn't bear to refuse them.

There was no other choice but to nod.

"So when do you want to take the exam?" he asked.

"Four o'clock!"

"No no five o'clock!"

"How about half past five?" Xie Ran asked in a drawling tone.

"Teacher Xiaojie is the best!" Lin Chaoxi shouted.

"Don't call me Teacher Xiaojie!" Xie Ran got angry.

——

actually……

In fact, Jie Ran is right. For ordinary children, a few more hours of review in math is unlikely to bring about a qualitative leap in your grades.

In short, it's what it should be.

At 5:30 in the afternoon, the children were already dizzy from reviewing.

After the test papers were handed out, Lin Chaoxi read through the questions and found that they were basically the same as the Jin Cup competition. There was just one more question worth 10 points, which was about knowledge points. There was also a question about Fermat's Little Theorem. Lin Chaoxi was shocked when she saw it. It seemed like junior high school competition knowledge. She was shaking when she did it. She tried her best to recall the relevant content, but it was still very difficult and she was not sure.

After the test, the whole class was very depressed. Normally, they all thought they were gifted, at least in mathematics, many of them were the best in the class. But this test paper made all the children start to doubt their lives.

Lin Chaoxi was also a little bored. She had only been thinking about helping Lu Zhihao and Huajuan all day, and had not done any analysis or analysis to see how much content in the book she had not yet mastered. She felt that she could not leave yet and had to work through the night.

"I think I might have 20 points!" Hanamaki raised his hand.

However, Xiaolu's eyes were red with tears: "It's so difficult, how can it be so difficult?"

Seeing this, Lin Chaoxi suddenly had a bad feeling.
