Chapter 704: Not just an answer (3/4)

Although it is true that speculation can achieve some goals, this is not what the teachers want to teach to children. Teacher Mu first praised the nuances and then drew a line on the small blackboard.
The small blackboard used by Teacher Mu is a magnetic blackboard, and the chalk is also a water-soluble dust-free chalk, which is more secure for children's health.
I saw that after painting this long white line, Teacher Mu said to the children: "For example, this is a line that my mother wants to cut, is it good?"
"Then rubbing the blackboard in my hand is the scissors in my mother's hand. If we wipe it off a little, even if it is cut," Mu teacher erased the blackboard and gave her a gesture, then encouraged. "Come, hey, come try it, see how many times you have to cut it to cut into five segments, slow down..."
What I like most is this part. I can do "experiment" with the teacher. Under the stands, Lu Weisha and Yang Qiqi are all envious of their faces.
I saw the little girl happily picking up the blackboard and rubbing it along the corner where the teacher had just crossed.

How many paragraphs are there now?
asked Mu.
"Two paragraphs!" He raised his small head and answered quickly. This little problem can't help but be smart.
"Continue, cut to five paragraphs and then stop." Mu encouraged.
She was very quick to understand. When she cut to the fourth, she stopped, but the little girl still had some hesitation.

How many paragraphs are there now?
asked Mu.
I just counted it up, only to hear that the little girl’s voice was as crisp as a big bead and a jade plate, and she said with a clear voice:
One, two, three, four, five...


Is it five segments?
Mu teacher asked with a smile.
The children under the stage were not alone at this time, and they clamored for the "five paragraphs".
He also nodded, but after the little girl finished the end, he hesitated again and raised the question in his heart: "But, teacher, I only cut it four times!"
The little girl is confused and magical about this.
How was it just cut four times?
Teacher Mu smiled and explained: "When we usually give fruit to children, if a watermelon is to be given to two children, is it necessary to cut a knife from the middle? Then if you want to give four children, is it a knife? And I have to cut a knife for the two halves of watermelon, a total of three knives?"
Usually, Mu teacher cuts the watermelon like this. The children who are screaming are sometimes stopped by Teacher Cai and Shen. They are drooling and watching Mu teacher cut the watermelon. At this moment, they all respond quickly. Screaming and responding.
This makes it easy to understand. Mu teacher then used the same principle as cutting watermelon to explain the principle that the rope was cut into five segments four times.
However, unlike other questions, the answer to this question is open, not just one!
Teacher Mu said with a smile: "Although it is possible to cut a rope into five segments in four times, in order to save energy and save time, the teacher only needs to cut one time to cut a rope into five segments."
Just cut once?
The children who responded quickly had "wow" and the children who reacted slowly were still looking at the teacher in confusion: "What is the teacher talking about?"
曦曦 belongs to the former, but she does not have
wow
, she is surprised: does it need to be cut four times? Why does the teacher say that it can be cut once?
The little girl is full of curiosity at the moment. Her watery eyes look up at Teacher Mu, and she is reluctant to wait. It seems that she is waiting for Mu’s moment to witness the miracle!
Teacher Mu did not let her return to her position. At this moment, she really took out a long red plastic packaging rope and said with a smile: "Hey, the teacher needs you to help the teacher now." ""
"Okay!" The little girl readily agreed.
Teacher Mu asked the donkey to fold the folding rope twice, then grabbed both ends and held it in his hand.
"Now the teacher has to cut it from the middle!" Mu teacher asked the side to take the packaging rope, so that her scissors should not be confronted, and other children can see it.
However, when she saw the bright scissors in her two small hands, she couldn’t help but whispered to Teacher Mu: "Teacher, I am afraid..."
"Don't be afraid, the teacher will be very careful." Mu teacher softly comforted.
At this moment, it was really a moment to witness the miracle. Even the most skinny Wang Xizhen couldn’t care about the noise at the moment, and looked at Mu’s scissors nervously.
Scissors licked and cut the packaging rope in the hand. Ms. Mu did not rush to talk. Instead, she put the scissors, a dangerous weapon for the children, and locked them up. The magnetic stickers allow you to have a number of packaging ropes on your hand.
In order to make other children see the results of the count more intuitively, Mr. Mu also gave one to himself after she finished the number. She used a magnet to attach the packaging tape to the magnetic blackboard.
"One, two, three..." I missed it, but it wasn't she who was counting, and the other children shouted excitedly.
It seems that they are also looking forward to miracles!
Finally counted down to the fifth article, blinking with a pleasant smile, spread out the empty hand, and surprised and happy to say: "Nothing!"

Is it five paragraphs?
Mu teacher asked with a smile.
"It's five paragraphs! It's amazing!" Chen Shiyun was below, and several children couldn't wait to scream.
He nodded, but she soon found a thing. The little girl pointed at the packing rope on the blackboard and said, "But the teacher, the rope, and this is too short!"
After folding, the length of the cut from the middle is of course different, some are very long, some are very short.
"It doesn't matter, because our question is, how can a mother cut into five segments, not a five-segment long one, so it can be cut into five segments with only one cut. It is okay." The observation ability is a bit of a headache and can only be explained in this way.
Why is it a knife and a five segment?
Teacher Mu did not explain, but left a space for thinking for the children. She also gave each child a packing rope to study on their small table, and after going back, with the help of mom and dad. Can the research be cut into five pieces with other cut times?
......
In the afternoon, Yang Lan will pick it up, and the little girl can't wait to tell her dad about the new knowledge she learned today.
"It's very good!" Yang said with a smile. "Daddy is working with you tonight, not just once or four times. There are still many possibilities in the middle. And, let's see how to fold and be able to Cut the rope into five lengths of rope of almost the same length."
"Okay, okay!" The little girl yearned for nowhere.
However, at night, not only Yang Lan and Yan were studying the rope, but Lan Xin also added it.
Lanzhou Kai went to Wucheng County, Jinling City to help Yang Lan buy land, and traveled for a long time without being at home, Yang Lan had to help guide Lan Xin's study!
Of course, the two little girls are together, playing and learning to play, this interest is even more intense.
"Cut watermelon is only a knife, cut a knife, because the watermelon is relatively large, but if you are an apple, you can cut it in half, and put the two halves together. You can cut it into four pieces with one knife..." When the little girl was playing with the folding rope, Murphy also looked at her with a small smile.
"Sister, you can learn quickly, learn, wait for my brother to grow up, you come to teach me, okay?" Murphy hugged the little cockroach up so that he could sit on his own arms and sit on his own In the arms, then shaking the little hand of the little guy, said in a small role.
Hearing, she lifted her small head and moved her eyes from the rope in her hand to her younger brother.
"Giggle, that Ma Ma, am I a teacher of my brother?" The little girl was happy to laugh, and said with a strong interest.
