"We're going to talk about basic mathematics today. Have you learned the multiplication table?"
In the early morning, after changing the medicine, Zhao Jun started teaching.
Now everyone's schedule has changed.
In the past, around four o'clock in the morning, Zhao Jun got up, Yan Shu came over to deliver some food, and then Zhao Zhen and the others came over to watch for a while before going to court.
After attending court, come back and listen to Zhao Jun and Yan Shu chatting, and get a glimpse of the true story of history from the chat.
Moreover, neither Zhao Jun nor Yan Shu dared to communicate too deeply at that time, so the information they obtained was scattered. They had to rely on Yan Shu to classify and summarize every day in order to have a clue, so they did not obtain much information.
Now that the staff of Nini Village has been established, Zhao Jun has ten students. After the first universe class, formal teaching began today, with a mathematics class.
In this way, Zhao Zhen and the others can go to the court first and deal with the affairs of the court. After Zhao Jun finishes his lecture, Yan Shu takes him outside to bask in the sun. The officials of the Song Dynasty can pretend to be the old, weak, sick and disabled who come out to bask in the sun. Chat with him.
But now everyone has become accustomed to gathering in the back garden first to check on Zhao Jun's situation before going to the morning court together, so when Zhao Jun started teaching, there were already dense crowds of people standing outside the door.
Everyone is watching.
Zhao Jun fumbled with the small wooden board, holding the charcoal pen given by Yan Shu in his hand, and asked everyone if they had learned the multiplication table.
Primary school mathematics is nothing more than addition, subtraction, multiplication and division, and you won't be exposed to negative numbers until around the sixth grade. He was worried that the children here would learn at a different pace, so he asked this question. In fact, he was not teaching, but learning.
Then I heard the clear child's voice below: "No~~~Yes."
"All right."
Zhao Jun didn't expect that the children's foundation was so poor. They hadn't even started to learn multiplication yet. He didn't know what the previous support teacher did. Did he only teach addition and subtraction?
"Then let's learn addition and subtraction today."
He fumbled on the wooden board, wrote one plus one with charcoal, then pointed at it and said: "Who knows what one plus one equals."
"two!"
the children shouted.
It seems that addition and subtraction are still somewhat basic.
Zhao Jun thought to himself.
"Does anyone know what three plus seven equals?"
he asked again.
Now no one gave an answer quickly. The children clapped their fingers, and after a while someone said first: "Ten!"
There is no rounding algorithm.
Zhao Jun roughly knew the level of the children, so he wrote down several sequence numbers such as one plus nine, two plus eight, three plus seven, four plus six, five plus five, etc. on the blackboard, and said to everyone: "Then let's learn today. Rounding algorithm..."
In daily life, addition and subtraction are generally only used for numbers with less than five digits. If there are more than five digits, a calculator is used. Many people even use calculators directly for more than two digits.
But primary school mathematics should still be taught. The so-called rounding algorithm is naturally a calculation method that can be rounded up by counting single digits first.
Zhao Jun wrote 1+6+9 on the blackboard and told everyone how to calculate this sequence.
To put it simply, 1+9 equals 10, and then 6 equals 16.
However, even with such simple arithmetic, the children still learned it in a fog, and it took them a long time to learn it.
After that, Zhao Jun taught several other types of classes and was so busy that his blood pressure almost rose.
There are two difficulties we are encountering now.
First, children have different abilities and different understanding speeds. He has to take care of those slow children and teach them over and over again.
The second is that he is blind, and he always fumbles when writing. Sometimes he often makes mistakes and has to erase and rewrite, which often takes him several minutes to complete a knowledge point, which makes him physically and mentally exhausted.
No wonder people say that math teachers are prone to hair loss. Fortunately, I am a Chinese teacher.
After class, Zhao Jun lay on the bed to rest, feeling grateful.
This time he was assigned to teach in Daliang Mountain because the previous batch of teachers had left and the next batch of teachers had not yet arrived. The organization asked him to set up an outpost first and arrange the students, and then send new ones in batches. Teacher comes over.
That's what support education is like. There are no fixed teachers, and there are even many teachers who are very excited when they first come, but end up complaining within a few days, and then give up halfway and run away secretly.
If it weren't for the two-year teaching quota, the organization would give him a lot of preferential treatment after passing the exam and in the future, and Zhao Jun wouldn't want to suffer this.
Now he is the only teacher in the whole school, and he is also blind. This teaching task is very arduous.
For the time being, I can only teach each subject slowly. I hope that the road up the mountain will be opened as soon as possible, so that I can go down to the hospital for treatment as soon as possible, and the new teacher will arrive as soon as possible to share the pressure with me.
Zhao Jun thought to himself.
And just when he had just finished a class, Zhao Zhen and others also turned around and walked towards the front palace.
At this time, it had already been about ten minutes before going to court.
Normally, they would be late, but today they originally planned not to be late, but just looked at Zhao Jun's door before going to court immediately. However, they ended up listening to a lesson, which delayed the time for going to court.
However, no one paid attention. The sky was still dark, and there was a faint gray light in the east outside the city wall in the distance.
On the complex road outside Qingshou Palace, guards surrounded the outside, and then the eunuchs and maids held lanterns to clear the way.
Zhao Zhen and several prime ministers did not sit in sedan chairs, but just walked.
As he walked, he said: "Zhao Jun once said that the national strength of future generations depends on the power of science and technology, and this mathematics is the basis of science and technology. After listening to this lesson today, it seems that it is nothing. It is very simple arithmetic. Qin and Han Dynasties Aren’t there arithmetic books left from that period?”
"Officials, I think that the mathematics taught by Zhao Jun today is probably only a very small part of it. Otherwise, since there were books in Qin and Han Dynasties, why didn't Qin and Han Dynasties have science and technology? Obviously, just like the water in the sea, simple arithmetic is just a drop of it. .”
Lu Yijian tirelessly persuaded.
"What you said makes sense."
Zhao Zhen listened very well.
Wang Zeng also said: "I think what is ingenious is not the simplicity of arithmetic, but its method. For example, the arithmetic of later generations is no longer one, two, three, four, five, six, seven, eight, nine, nor lowercase numbers, but replaced by "Dashi", is this good for writing? Maybe this is the reason why "Dashi" became popular in later generations."
"Well......"
Zhao Zhen pondered and nodded: "Does the Prime Minister mean to promote it nationwide?"
"It is indeed good for writing, but several of the numbers are good for erasing. This is a hidden danger, so don't rush and take a look first."
Wang Zeng said: "I think it has another wonderful effect, that is, it can exercise people's thinking ability and use rounding methods to quickly obtain arithmetic answers. Who can ordinary people think of this?"
"This should be the mathematical logical thinking that Zhao Jun just mentioned."
Song Shou said: "Mathematics can exercise people's brainpower and increase intelligence. Perhaps it is because of learning mathematics that we can learn other science and technology."
"yes."
Wang Sui said: "We are getting older and older, and our brains can't turn around. It's still young people like them who can think about things. Maybe we can ask Zhao Jun for advice on mathematics later."
The group of people quickly arrived at Chui Gong Hall along the complex road, preparing for today's morning pilgrimage.
