After waiting for Xiong Da to leave, he said embarrassedly: "The head of the family..."

Li Dawei hurriedly stopped: "Let's call me Brother Dawei in private, it's so kind!" ”

"Uh~ Brother Wang said it specially, not in private, this is the rule, saying that there are many of us, we must establish rules, and there are no rules."

"I just don't say no"

Mo Waitian shook his head and said, "I know that the head of the family is a good person, but what Brother Wang said is right, there are no rules."

"Okay, it's good that you're happy" Li Dawei was helpless, "What did you want to say just now?" ”

"There aren't many of that kind of soft steel," Mo Beixian said with some embarrassment, "I use a lot of other things." ”

"Hey, what should I do, didn't I say I'll leave it to you to study? If it's gone, it's gone," Li Dawei waved his hand and said, "Didn't you research other steels?" It's okay to use it, but it's not like it's going to be used for a lifetime. ”

"Thank you to the head of the family" Mo waited and hugged his fists and said: "The whimsy of the head of the family, even the entire Mo family is unmatched, and I have never heard of this music box and perfume nozzle at the beginning."

"It's just simple physics, as long as you are willing to learn it, I can teach you," Li Dawei said, pointing to his head, "There are many of them." Oh, by the way, Brother Wang likes to join in the fun the most, how is it mysterious today, why are there other important things? ”

"That music box, according to the hint of the head of the house, the tone problem has been solved. The villain part above, Lu Mu has already carved it, and Brother Wang, Sister Wanting, and Sister A Xiu have been listening there, and they have made suggestions to improve it by the way. ”

Hey, what about the new gadgets, Li Dawei thought maliciously that Wang Fuli was with Ah Xiu. smiled: "You still have to help Brother Xiong, this sprinkler is now only you can do." ”

The small music box, as if it has magic power, with it as the center, three layers inside and three layers outside, more than a hundred people are silent, only the villain above is gracefully turning in circles with the music.

The children didn't go to class, and they all gathered here, their eyes full of yearning.

Wang Fuli coughed and said, "Children, I've been listening to it for half an hour, do you think this 'music box' is good?" ”

"Good!"

"This was researched and invented by your big viagra. Big Viagra said that as long as anyone reads seriously, they can receive a music box on their birthday. In addition, Brother Viagra has a lot of powerful skills, do you want to learn it? ”

"Yes!!"

"Okay, then let's go to your big viagra brother now, let him teach you new things, whoever performs well can get such a reward."

Wow... Like a tsunami, more than 100 children shouted 'Great Viagra' in their mouths and scattered in a hurry.

Seeing that the children had left, Mi Wanting said: "Isn't it good for us to calculate the 'head of the family' like this?" ”

Wang Fuli said: "You haven't been with the head of the family for a long time, and it's normal that you don't know some things. The head of the house thinks differently, and he himself will not take it seriously if we don't take measures. To tell the truth, if it weren't for us and this group of children, the head of the family would not have go. ”

Ah Xiu's eyes were full of yearning and said: "The head of the family is really a good person, it is our blessing to be able to follow him!" ”

Wang Fuli said with a smile: "Ah Xiu still has the ability to let the head of the family draw the appearance of 'Miss Sima'." Now it is necessary to write this poem. ”

"Poetry?" Ah Xiu took a look, a little embarrassed, and couldn't read.

Mi Wanting took it and looked at it, and couldn't help but read: "As soon as the golden wind and jade dew meet, they will win countless in the world. If the two love for a long time, how can it be in the morning and twilight... The writing is so good, I didn't expect Brother Wang's poetry attainments to be so high. ”

This one is a little embarrassing, "I didn't write this, it was the head of the family who said it in passing!" ”

"The talent of the head of the family is really unfathomable, and it feels like he can do anything." Ah Xiu sighed, and then said with some doubts: "It's just why the head of the family suddenly made such a 'poem'"

"Hehe, I just discussed it with the head of the family!" Wang Fuli's face did not change, and then said: "We are going to write this poem under this painting, and then put it in the music box, what do you think?" ”

“... Brother Wang, you brought all the children to the head of the family, you just don't want the head of the family to have a chance to come! ”

"What's the matter? The head of the family likes children, don't I create opportunities for him? Wang Fuli resolutely denied it, "Do you two think that if Miss Sima receives such a birthday gift, will she be very surprised and moved, and will have the urge to marry the head of the family." ”

"Of course!!" The two women spoke in unison.

"That's good, it's not in vain for our calculations!" Wang Fuli said: "The head of the family himself definitely can't write, my handwriting is average, let's work hard!" ”

The beautiful and expressive portraits, the tactful and affectionate poems, looking at the complete 'work', Mi Wanting's eyes appeared confused.

Wang Fuli nodded with satisfaction, then pressed it somewhere in the music box, popped up a secret door, carefully put the silk cloth in, closed the secret door, and let out a sigh.

Seeing that the two girls were in a daze, Wang Fuli smiled and said: "I just saw that the perfume of the head of the family has been successfully developed, and it seems that there are several fragrances, all of which smell very good, so hurry up and pick the one you like and ask." ”

Yes... It's true? Shout~

Wang Fuli shook his head, women are women, and they like these things. It seems that the head of the family is a master of 'pickling girls', as soon as these two 'artifacts' are shot, which woman can stop it, at least half of the success.

Half, right? Wang Fuli scratched his head, what was wrong?

It's broken, I forgot that there is also a 'Huan Qianqian' who is recuperating from injuries.

No, a qualified 'housekeeper' must also be a scope to worry about, for this Huan Qianqian, the head of the family doesn't have that kind of idea, it's sad, I have to find a way to 'help' the head of the house.

Li Dawei didn't know that he had been being 'calculated' by his retainers, and he was delighted with the children's enthusiasm and studiousness.

Ninety-nine multiplication table, children can already memorize.

Mathematics can teach something new, such as the 'Arabic' numerals 0, 1, 2, 3...

As a teacher, David Li knows that this kind of representation can greatly improve the way of thinking and the speed of calculation in mathematics.

Combination of lectures and exercises, entertaining and teaching.

Simple addition and subtraction, calling the children out, increasing and decreasing the number of people, and then counting, it is really not difficult to understand, even the four bears who are 'guarding' next to it have no problem.

The four bears used to be difficult to count, but now they can count.

Those with strong comprehension skills, such as 'Xiaocao' and 'Dog Baby', have mastered multiplication and division.

It's so fulfilling.

You can also have some physics teaching, no, it should be 'natural', to improve children's interest, it's easy, let's have a simple question: there is a sound when you speak, there will be a sound when you hit, there will be a sound when the sword dances, there will be a sound when you put a stinky fart... So how does the sound come about?

Everyone looked at each other and answered a variety of answers.

Li Dawei will praise any answer from the children, and will not ridicule their naïve or even absurd ideas, scientific inventions and creations come from all kinds of whimsical ideas, and the habit of thinking must be cultivated.

Of course, there are other questions to let the children know that the answer is not perfect.

After a lot of commotion, Li Dawei finally came to a conclusion: vibration

Sound comes from vibrations.

I took a leaf at random, rolled it up, and played a simple tone; If you pull out a straw pipe, you can also play it;

The children have all kinds of examples, all kinds of blowing and not blowing.

In the end, Li Dawei took out the 'flute' from the leg guards and played a song of 'little grass', and the children joined in unison.

'Da Niu' asked a question that surprised Li Dawei: "Brother Da Wei, why does it sound better to blow it out with your flute than with leaves?" ”

It seems boring, but with thinking about the problem, Li Dawei gave full praise, and the 'big cow' blushed.

"This one is because it has a cavity that resonates with the sound."

'Xiaocao' has the highest talent and asks, "Is it possible that we can make all kinds of musical instruments as long as there is a cavity!" ”

"Yes" Li Dawei affirmed: "Xiaocao's idea is completely correct, and the 'big drum' is like this." Of course, this needs to be practiced, so I will give you an assignment for you to make an instrument that has never been done before. You can work on it with a few people, or you can ask the adults for help, but you'll have to design the style yourself. Now I'm going to teach you how to draw. ”

"Good !!"

The convivial atmosphere is contagious.

And Huan Qianqian, who was watching this lively scene from a distance, flashed a trace of loneliness in her eyes, and turned around and entered the cave again.
