Ten years of trees, 100 years of people.

Education is the cornerstone of the tribe's development......

Compared with the tribe's education plan, the matter of going south to build the second tribe can indeed be pushed back.

As a person who has received compulsory education and deeply understands the meaning of education, Han Cheng easily made a choice between the two.

After having a rough idea in his heart and making a decision, Han Chengcheng told Senior Brother Wu, Shi Shi and a few others about such a thing.

As always, I told them what it meant to do so.

And the reaction of Wu and Senior Brother is no different from the past, Shenzi said yes, and also told himself and others the meaning of doing this, then it will definitely be like this.

Although there are some things that I and others don't quite understand, and I asked Miko about them, and after Miko explained them, he still didn't understand them, but this didn't prevent him and others from supporting Miko strongly.

Even, some people such as Wu and Shi Shi and Yuan also wanted to participate in the revision of the textbook.

For such a thing, Han Cheng naturally agreed. It is impossible to rely on him alone to revise such a thing as a textbook.

On the one hand, this is because textbooks seem simple, but in fact they are very tedious, and there are many things to consider and do.

On the other hand, as a later generation, Han Cheng's thinking will still be different from that of this era many times.

Many things that he takes for granted and are not difficult at all can be difficult for people of this era to scratch their heads.

With the addition of witches, stones and others, the textbook can be more in line with some people of this era, so that the difficulty will not be too huge.

Chinese textbooks are relatively easy to compile, after all, there are already a lot of famous texts in the tribe, and these famous texts can be sorted according to their degree of difficulty, and then some chapters can be added to build a general framework.

For example, Han Dashenzi was lying on the table at this time, recreating the famous articles of later generations.

Now he is writing "The Little Donkey Crossing the River".

In fact, Han Cheng originally wanted to copy it as it was.

After coming to this era, he has copied a lot of things from later generations, and now there is nothing bad about being a copyist, for him, there will be no psychological pressure at all.

After all, such excellent qualities have existed since ancient times, for example, the elites of the hundreds of schools of thought in the Spring and Autumn Period and the Warring States Period are you copy me, I copy you, a school has a very good theory, after some time, after a little whitewashing, the other school will use it with peace of mind.

The confluence of the three schools of Confucianism, Buddhism and Taoism in the back is also similar.

In this regard, Master Lu once made a very incisive overview - can the things of the reader be called copying?

However, considering that there are no horses, no cows, and no mills in the tribe, in order to be more relevant to the actual situation in the tribe, so that the children in the tribe can better understand and accept when they learn, so Han Cheng naturally changed "Pony Crossing the River" to "Little Donkey Crossing the River".

And the old cattle inside were changed into larger rhinoceros that had appeared in the tribe.

I went to the mill and wanted to go to the other side of the creek to eat better grass.

This kind of thing, for Han Cheng, a person from a liberal arts background, is simply not too casual.

After writing, I picked it up and looked at it myself, and appreciated it, except for the words that were a little ugly, there was nothing wrong with the rest.

Of course, since it is a textbook, it cannot just be a dry text.

At the end of each text, you also need to do something more interesting.

For example, the first rare words that appear in the back are marked out, so that people can read and write a lot.

For example, at the end of the text "The Little Donkey Crossing the River", Han Chengcheng asked, why didn't the little donkey cross the river the first time? Why did it pass later? What do we learn from the story of the donkey crossing the river?

There are also small activities such as playing roles by role.

In addition to "Little Donkey Crossing the River", Han Cheng also made slight changes to "Crows Drinking Water" and "Snipe Clam Fighting" and wrote them.

It's really good to study these little stories with some truth as texts.

This allows people in the tribe to learn Mandarin and Chinese characters at the same time, as well as learn the principles of how to behave and behave.

In addition to these texts, which were adapted on the basis of later texts, Han Cheng also made some original works.

For example, after the original leader of the sheep tribe was caught by the people of the semi-peasant tribe, he would rather take the initiative to hit his chest against the weapon of the enemy who threatened him, rather than tell the real experience of the tribe's location.

In order to report the enemy's attack on the Tongshan settlement to the people of the main tribe as soon as possible, so as to strike at the invading enemy, the two people chose to gallop in the starry night, and after going down all the way, they could hardly walk as the prototype of "We Are Not Tired".

These passages carry a strong educational significance of loving the tribe, which not only allows the people in the tribe to remember the feats that these people have done, but also allows those who study these texts to understand what it means to love the tribe and what to do when the tribe is in danger.

In addition to these, Han Cheng also used lameness as a prototype and wrote an article called "I am a carpenter" as a text.

The main thing is to write about how the lame was injured in the hunt at the beginning, from a useful person to the tribe, to a burden in the tribe, and suffered.

Then seize the opportunity, die and make achievements elsewhere, and then become a useful person to the tribe again.

While making great contributions to the tribe, he has made his status higher and surpassed his original status.

Through their own efforts, complete the counterattack of life.

It is used to encourage people in the tribe not to give up when they encounter setbacks and difficulties.

If one aspect fails, maybe through hard work, you can succeed from somewhere else.

After writing a text called "I Am a Carpenter" based on the experience of lameness, Han Cheng suddenly had the urge to use his own experience to write an article called "I am a primitive person".

Mainly introduce, how a person from the later generations came to the primitive society sadly and inexplicably, and then experienced all kinds of tragic things in the primitive society, and later, instead of assimilating the primitive people in the tribe into modern people, he was assimilated by the vast number of primitive people in the tribe to move closer to a semi-primitive people, and some of them liked the unproductive behavior of the primitive society.

Later, considering that such a thing was too sad, not upward enough, and did not have too much educational significance, but was easy to have a bad influence, Han Cheng extinguished this idea again.

In addition to these, Han Cheng also took the development history of the Qingque tribe as the prototype and wrote an article called "My Tribe", which mainly introduces how the tribe has grown step by step from an inconspicuous, poor and backward tribe through hard work.

Han Cheng's main purpose in writing such a text was to let the people in the tribe understand the importance of hard work.

At the same time, I also want the people in the tribe to remember the history of the tribe, especially those children who were born and grew up after the development of the tribe, so that they can understand the past of the tribe and let them know that the good life now is not blown by the wind, but by the people in the tribe, little by little.

Only by remembering history and knowing the roots of your tribe can you go better in the future and develop your tribe stronger.

This is also why, logically speaking, mathematics, a subject that many people in the tribe do not know very well, is the reason why Han Cheng should first start to deal with and compile textbooks, but Han Cheng started with Chinese textbooks first.

Mathematics can make people wise and make people's thinking more rational, but language plays a greater role because it can teach people a lot of truths and have a subtle impact on people.

All kinds of texts, some long and some short, already existed, plus Han Cheng's adaptation and self-writing, these together have a total of sixty-four.

So many texts, revised into a book, are enough for these children in the tribe to learn for a while.

After setting these texts and writing things like after-school activities later, Han Chengcheng put the matter aside and called the stone and the witch over to let the two of them complete the follow-up things.

The main thing is to sort the texts according to the principle of easy to difficult, and then find out the new words that have not been learned from the following texts, select them specifically, mark them, and list them as key learning objects.

At the same time, it is also possible to follow Han Cheng's previous model and ask enlightening questions later according to the content of the text.

After all these things were done, all that remained was to transcribe the draft version of the text to a blank textbook.

The textbook, when Han Cheng was compiling the text, had already been prepared, that is, the paper was cut into a length of 25 centimeters and a width of 15 centimeters, and then bound.

There were no staples, so the tribesmen first pierced the holes with an awl that pierced the skin and put it on with a leather rope.

Worried that this alone would not be strong, I glued it there again.

There were no printers in the tribe, and there were no printing presses, so textbooks and other things had to be transcribed by hand.

Han Cheng has considered the matter of printing, but if he wants to get it out of scratch, it is not something that can be done overnight.

It takes a lot of time and energy, and after going through experiments, revisions, and adjustments, it is possible to get it out.

Teaching in the tribe is a work in progress, and textbooks need to be put into use as soon as possible.

Therefore, Han Cheng didn't work printing technology for the time being, and wanted to use stupid methods to create a batch of textbooks to use first, and then start to let people slowly learn some technology in this area after saving them.

Fortunately, the population of the tribe is not that large, and it is not impossible for two or three people to use a book temporarily.

Moreover, if the printing technology is pointed, the paper that can be produced in the tribe at present is estimated to not meet the requirements, and it cannot be printed, and the paper also needs to be improved.

These are all things that need to be overcome, not to say, get a carrot and carve a chapter, dip it in some ink, and poke it on the paper.

It's not that simple.

If there is such a simple thing, people on the European continent will not call it one of the four great inventions.

The matter of the Chinese textbook was roughly determined, and the remaining details were handled by Wu and Shishi, and copied on the blank textbook, Han Chengcheng began to prepare the math textbook in full swing again.

In view of the fact that the people of the tribe accept these additions and subtractions relatively quickly, and in the case of multiplication and division of these, Han Chengcheng directly put 1x1=1 1x2=2 on the first page...... These ninety-nine multiplication tables are written down in order from high to low.

This inspiration came from the pencil case used as a child.

At that time, if you opened the pencil case, you could see the ninety-nine multiplication table printed on it.

At that time, Han Cheng was able to write it down, and the pencil case was very creditable.

As long as you bomb indiscriminately enough, there will always be a time to write it down.

As long as you write down the ninety-nine multiplication table, it is easier to do simple multiplication and division, which is considered to have a foundation.

After the ninety-nine multiplication table at the beginning was written, Han Chengcheng began to write the numbers from 1 to 10.

In order to make it easier for the children in the tribe to memorize, Han Cheng also carried the children's rhymes he learned when he was a child - 1 like a pencil to write and draw, 2 like a duckling quack, 3 like ears to listen to sounds, 4 like a small flag hulala, 5 like a scale hook to weigh things, 6 like a spoon hanging on the wall......

At the same time, he also used his skills as a soul painter to draw as many numbers as possible to correspond to them.

As for 0, Han Cheng drew an egg underneath.

After writing out the numbers, Han Chengcheng began to work hard to compile the book.

Xiao Ming, a classmate in the second class of the third grade, and Xiaohong Xiaofang all appeared.

The problems are very simple, and the example problems are explained first, and then some similar problems are given later, so that the students in the tribe can imitate the example problems to calculate these problems.

Imitation of more will do.

For example, in the first example question, he wrote - Xiao Ming has three lollipops, and Shenzi rewarded him with a lollipop, and now Xiao Ming has a total of how many lollipops?

Then we will explain it below, and finally list the equation of 3+1=4.

The later subtraction is basically modeled after the previous addition.

For example, Xiao Ming has three lollipops, he ate one, and how many are there now?

Of course, in addition to lollipops, there are also arithmetic problems such as dividing fruits and fish.

At the beginning, it is all within ten of the addition and subtraction, and later it will gradually develop to less than a hundred.

And it is no longer a simple plus a few, a few minus a few, but has developed into a few plus a few plus a few equals, a few minus a few plus a few equals a few.

As the numbers that need to be calculated become larger, and the number of addition and subtraction operations becomes more and more complicated, Han Chengcheng wrote out the addition and subtraction formulas in a timely manner.

Just like when I learned simple addition and subtraction before, I also learned addition equations first, and only after learning certain addition example problems and using them more proficiently, did I start to write out the subtraction equations for people to learn.

Later, the number of additions and subtractions will be expanded to thousands, tens of thousands, and hundreds of thousands.

As long as you are proficient in addition and subtraction, these are not a problem.

After addition and subtraction, it is multiplication and division, and like addition and subtraction, it is learned from a simple multiplication of a few, first learning multiplication, and then learning division.

Xiao Ming, Xiao Hong, Xiao Fang and some other hated children reappeared, each holding a lollipop or something to give people problems, especially to make it difficult for the children in the tribe.

When it comes to division, Han Chengcheng gets the remainder out.

At this time, in fact, the remainder is the most in line with the actual situation of the tribe.

After all, there are many things that cannot be divided into several parts.

Of course, this is only the initial stage, and when you go deeper and deeper, the decimal will appear.

After multiplication and division were written, Han Cheng mixed the four operations of addition, subtraction, multiplication and division.

Multiply and divide first, then add and subtract, there are parentheses, first calculate the operation rules in the parentheses, etc., which were also moved by Han Cheng.

Unlike Chinese, mathematics cannot be made up randomly, and the questions can be written according to the times, but the laws of operation cannot be changed, at least Han Cheng himself does not have the ability to change this.

At the same time, he also wrote out the operation rules such as (a+b)xc=ac+bc, and also used them to explain the example problems, so that the people in the tribe could understand more easily.

Of course, this is more advanced mathematics.

In the first math book, the four operations are learned, and even if it ends here.

In the second volume, Han Cheng planned to delete the geometry on the basis of the first volume, such as calculating the area and perimeter of triangles, squares, trapezoids, circles, etc.

Later, you will learn about the volume of three-dimensional figures, as well as the surface area.

Of course, Han Cheng did not immediately start writing this second volume of mathematics books, but stopped there.

Because the knowledge on this first volume is enough for the people in their tribe to learn for a while.

According to his estimates, since he returned from Jinguan City in the south, the children of the tribe may not be able to finish learning it.

The second volume of the math book, when he was in Jinguancheng, was delayed in compiling it.

It just so happens that there will be more time at that time, and it will be more complete and systematic.

After carefully checking the draft of the first volume of the mathematics book, Han Cheng asked the circle that was laid down here to copy it into the blank textbook, and when copying, he specially told the circle that he must be serious, mathematics is a very serious matter, and a wrong number will lead to a major error in the operation result.

Holding the draft of the math book compiled by Han Cheng, Yuan, who had already read it with fascination, naturally nodded busily.

Before Yuan transcribed, Han Cheng first took a pen and copied a blank textbook as a model.

At the same time, the page number is written in the lower right corner.

Because the paper in the tribe is not mature enough and the quality is not good enough, the textbook can only be written on one side, unlike the textbooks of later generations, where the content can be printed on both sides.

It is also because of this that the textbooks that come out are relatively thick.

In addition to explaining that Yuan should not make mistakes, Han Cheng also instructed her that it doesn't matter if the characters are bigger or smaller, but the content on each page should be the same.

It can't be said that after copying this page, see that there is still a lot of room left, and copy the content of the next page to this one.

This is true not only for math books, but also for language books that are produced first.

Yuan is really an outlier, and he is the best candidate for the tribe to be a math teacher.

Others seem to think it is very boring, and even after reading it, she thinks that the math book is big, but she can read it with relish.

When copying is carried out, copying and copying will lead to contemplation.

Sometimes, I will look at the book and laugh, and sometimes, I will slap the desk full of excitement.

After hearing the sound and feeling the pain in his hand, he came back to his senses, and then smiled at Han Cheng who was not far away, and then copied the book.

But it won't be long before that happens again.

Han Cheng is also not surprised by this, he has been running to the Internet café a lot, what kind of god man and god operation have been seen, I don't know how much worse Yuan's state is compared to them.

Moreover, Han Cheng is very happy to see this state of Yuan, after all, after he has made these things almost one, he needs to quickly take people to Jinguan City in the south, and when he leaves, the heavy responsibility of teaching mathematics in the tribe will fall on Yuan, the first person in mathematics besides him.

This state of hers is very conducive to her to read the textbook as quickly as possible and prepare for the next step of teaching.

likes to see the circle enter this state, not only Han Cheng, Wu also likes it very much.

Because Yuan is not only fascinated by these problems and rules of operation during the day, but also holds a copied book in his hand, sits under the oil lamp and reads it non-stop, and at the same time picks up a pen and paper to do calculations.

The rest of the things are not taken to heart by her.

Wu, who always felt tired, suddenly felt a lot more relaxed at this time, and even walked with energy.

"Miko, what does this thing mean?"

"This one is pronounced 'a' and that one is pronounced 'b'...... They mean that they represent an unknown number, and they can also be replaced with any number, and what they express is a kind of law of operation.

Not only can multiplication be represented by them, but addition and subtraction can also be ......"

When researching the topic, when he encounters something that he can't think of, Yuan will ask Han Cheng, and Han Cheng will answer Yuan in as much detail as possible......
