By the time Fang Nan and Hu Xiaoya walked out of the gate of Hu's house, the sun had already set, and it was expected that in about two quarters of an hour, the sky would be completely dark.

After walking around the open space twice to digest and digest the food he ate for dinner, Fang Nan pulled Hu Xiaoya to the house where he lived.

"Xiaoya, I'll teach you to read and write first."

"Okay." Hu Xiaoya readily agreed.

Under the stove of Fang Nan's house, a firewood pile slowly burned, emitting light and heat to the surroundings, Fang Nan and Hu Xiaoya sat in front of the stove, holding a handful of sand to the ground, flattening it, and holding a small wooden stick in their right hand.

"Now I teach you pinyin, learn pinyin before learning the text, you can grasp the text faster, look at the pinyin letters I wrote on the ground, and then read a, o, e with me."

“a、o、e。”

Fang Nan read very slowly, and Hu Xiaoya easily read the approximate pronunciation of the three pinyin letters for the first time.

The pronunciation of the pinyin alphabet of Fang Nanjiao Hu Xiaoya is actually slightly different from that of the previous life, the words read in Chinese pinyin in the previous life are called Mandarin, and the accent of Qingshanzhai is the same as the main accent of the current population living in Guangdong, but it is a dialect for Mandarin.

Fang Nan didn't plan to bring Mandarin into Qingshanzhai, it would be too troublesome, so Fang Nan changed his thinking, took his current speech accent as a standard language, and modified the pronunciation of the pinyin alphabet to a certain extent.

“a、o、e。”

“a、o、e。”

Fang Nan read, Hu Xiaoya listened first and then said, after several times in a row, Hu Xiaoya's pronunciation was almost the same as Fang Nan's pronunciation, and then Fang Nan taught Hu Xiaoya to write these three pinyin letters.

There are a total of 63 Chinese pinyin, 23 initials, 24 finals, and 16 syllables for overall pronunciation.

Hu Xiaoya has more time to study with Fang Nan, and will learn Chinese pinyin faster, but on the first day of learning Chinese pinyin, Fang Nan only taught 12 pinyin, and used up some time for Hu Xiaoya to initially learn to read and write 12 pinyin, the Chinese class ended and began to take math class.

The beginning of math class is also relatively simple, that is, it is called counting, 0, 1, 2, 3, 4, 5......

Counting, anyone can, people in Qingshanzhai can't read, but they can also speak, in the same way, they don't know numbers, but they can also count, counting is a word that can be used on weekdays, a wooden stick, two eggs, three apples and so on.

Not being able to count is equivalent to not being able to speak, how can people not be able to speak, there will be some problems with children's counting, as they grow older, counting within a hundred will definitely be, and there will be some simple addition and subtraction.

When teaching counting, Fang Nan also taught Hu Xiaoya to write these Arabic numerals, but Fang Nan changed the name of "Arabic numerals" to "abbreviated numbers".

Abbreviated numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, lowercase numbers 0, one, two, three, four, five, six, seven, eight, nine, ten, uppercase numbers zero, one, two, three, four, wu, lu, qi, 捌, jiu, pick.

Here's another very interesting thing about lowercase and uppercase numbers:

In order to oppose corruption, Zhu Yuanzhang formulated strict laws and regulations to punish economic crimes, carried out technical precautions in financial management, and implemented some effective measures, changing the Chinese characters "one, two, three, four, five, six, seven, eight, nine, ten, hundred, thousand" to capitalize the Chinese characters that record the numbers of money and grain, and using "one, two, three, four, wu, lu, qi, 捌, jiu, pick, hundred, thousand" is one of the important ones.

It stands to reason that words should develop in the direction of being easy to write, but in terms of numbers, they are simple and complex again, which is simply turning back the clock on history.

As for when lowercase numbers began, I am not sure, but in the third century AD "Sun Tzu Sutra" already has this usage: "One from ten horizontal, one hundred and a thousand stiff, a thousand and ten look at each other, ten thousand and ten are equivalent." ”

Fang Nan teaches Chinese pinyin, simplified characters, and abbreviated numbers, all of which are conducive to students learning words and arithmetic faster.

Soon the math class was over, and at this time there may have been villagers who had fallen asleep, Hu Xiaoya did not rush home, but reviewed the pinyin and abbreviated numbers that she learned tonight, and saw that there were no mistakes, so she returned to Hu's house under the escort of Fang Nan.

Fang Nan and Hu Xiaoya are both twelve years old, and they can no longer be treated as children, before the two got married, Hu's father and Hu's mother did not allow the two to live together, and only the three days when Fang Nan was in a coma were an exception.

Sending Hu Xiaoya home, Fang Nan came back and played a few times in the open space in front of the house, and then washed a little before going back to the house to sleep.

Fang Nan plans to teach physical fitness boxing to students in physical education classes in the future, which can be of great help to exercise their bodies.

Of course, physical fitness boxing can not be compared with the so-called martial arts, physical fitness boxing is fitness gymnastics, don't think that after learning to strengthen the body, you will be able to use one as ten, and it would be good to be able to hit two at a time.

A new day has arrived.

Class leader Zhou Shishi walked into the house where Fang Nan lived and reported: "Report to the teacher, everyone has arrived, please ask the teacher to attend class!" ”

"Let's go, let's go to class." Hearing Zhou Shishi's report, Fang Nan nodded to Zhou Shishi, and then Hu Xiaoya beside him said a word.

The three of them walked out of the house together, Zhou Shishi walked faster, quickly returned to his seat, and when Fang Nan stood in front of the blackboard that had been erected in front of the house, Zhou Shishi shouted loudly to his classmates: "Stand up!" ”

The next moment, all the students in the temporary classroom stood up and shouted together, "Hello teacher! ”

Fang Nan glanced at all the students, and then replied, "Hello students, please take a seat and start class!" ”

Next to her, Hu Xiaoya also held a stool and sat in the upper right corner of the temporary classroom, lecturing is Fang Nan's task, Hu Xiaoya walks as a teacher's assistant, and when the teacher needs to go down to see how the students write, Hu Xiaoya is responsible for the girls' side, and Fang Nan is responsible for the boys' side, so she can share some of Fang Nan's pressure.

"Today officially teach everyone to read and write, before learning words, to learn pinyin, this is not a learning method outside the mountain, as long as you learn pinyin, the efficiency of learning words will be greatly improved, today we have to learn a total of 12 pinyin."

After Fang Nan finished speaking, he picked up the homemade chalk and wrote twelve pinyin such as a, o, and e on the blackboard, and then Fang Nan took a wooden stick with two little fingers thick and more than a foot long, pointed to the pinyin on the blackboard and said to the students: "Read with me, a!" ”

“a！”
