Chapter 704 Not Just An Answer (34)

Although it is true that opportunism can achieve some goals, but this is not what the teachers want to pass on to the children in this class. Teacher Mu first praised Xixi for her meticulous observation, and then drew a line on the small blackboard.

The small blackboard used by Mr. Mu is a magnetic blackboard, and the chalk is also water-soluble dust-free chalk, which is more secure for the children's health.

After Mr. Mu finished drawing the long white line, he said to the children, "Let's say, for example, this is a line that mom wants to cut, okay?"

"Then the blackboard eraser in Xixi's hand is the scissors in mother's hand. If we erase a little bit like this, we can even cut it open." Teacher Mu handed the blackboard eraser to Xixi, taught her to gesture, and then encouraged. , "Come on, Xixi, try it out and see how many times it takes to cut it into five sections, slow down..."

What Xixi likes most is this part. She can cooperate with the teacher to do "experiments". Under the stand, Lu Weisha and Yang Luoqi are all envious.

I saw the little girl happily picked up the blackboard eraser and wiped it with the corner along the spot where the teacher had just drawn.

"How many paragraphs is it now?" Teacher Mu asked.

"Two paragraphs!" Xixi raised her head and answered quickly, this little question was hard for the clever Xixi.

"Go ahead, cut it to five paragraphs and then stop." Teacher Mu encouraged.

Xixi realized it very quickly. When she cut to the fourth time, she stopped, but the little girl still hesitated.

"How many paragraphs is it now?" Teacher Mu asked.

Xixi counted up, only to hear the little girl's voice clear and clear like a big pearl falling on a jade plate, and counted happily: "One, two, three, four, five..."

"Is it the fifth paragraph?" Teacher Mu asked with a smile.

The children in the audience were also unwilling to be lonely at this time, and they scrambled to shout "Five Duan".

Xixi also nodded, but after the little girl nodded, she hesitated again, and raised the question in her heart: "But, teacher, I have only cut it four times!"

The little girl is confused and magical about it.

Why only cut it four times?

Teacher Mu explained with a smile: "When we usually give fruits to children, if we give a watermelon to two children, do we have to cut a cut from the middle? Then if we want to give it to four children, is it necessary to cut a cut? , and cut each of the two halves of the watermelon, three in total?"

Teacher Mu usually cuts watermelons like this. The greedy children are sometimes stopped by Teacher Cai and Teacher Shen, and drooling from a distance to watch Teacher Mu cut watermelons. Yelling in response.

This is easy to understand. Teacher Mu went on to explain the principle of cutting the rope four times into five sections using the same principle as cutting a watermelon.

However, unlike other questions, the answer to this question is open-ended, not just one!

Teacher Mu smiled again and said, "Although it takes four times to cut a rope into five sections, in order to save energy and time, the teacher can cut a rope into five sections with only one cut."

Only cut once?

The children who responded quickly had already cried out "wow", and the children who responded slowly were still looking at the teacher in a daze: "What is the teacher talking about?"

Xixi belongs to the former, but she doesn't have "wow", she is surprised: doesn't it need to be cut four times? Why did the teacher say that one cut is enough?

The little girl's mind was full of curiosity at the moment. Her big watery eyes looked up at Teacher Mu, and she couldn't bear to blink, as if she was waiting for the moment when Teacher Mu staged a miracle!

Teacher Mu didn't let Xixi go back to her place. She really took out a long red plastic wrapping rope and said with a smile, "Xixi, teacher needs you to do teacher a favor now. ."

"Okay!" The little girl readily agreed.

Teacher Mu asked Xixi to hold the wrapping rope and fold it twice, and then hold both ends in her hands.

"Now the teacher wants to cut from the middle!" Teacher Mu asked Xixi to hold the packaging rope on the side, so that her scissors could be seen by other children without facing Xixi.

But Xixi saw the bright scissors gesturing between her two small hands, she still couldn't help whispering to Teacher Mu: "Teacher, I'm afraid..."

"Don't be afraid, the teacher will be very careful." Teacher Mu comforted Xixi softly.

At this moment, it was really the moment to witness the miracle. Even the most skinny Wang Xijun couldn't care about the noise at the moment, and looked nervously at Teacher Mu's scissors.

The scissors snapped open the packaging rope in Xixi's hands. Teacher Mu didn't rush to speak, but first put away the scissors, which were dangerous to children, and locked them before taking out a colorful Magnetic stickers, let Xixi count how many pieces of packaging rope she has now.

In order to let other children see the counting result more intuitively, Teacher Mu also asked Xixi to pass one to herself after counting one. She used a magnet to stick the packaging tape on the magnetic blackboard.

"One, two, three..." Xixi read, but she wasn't counting alone, and the other children also shouted excitedly.

As if they were expecting a miracle too!

Finally counted to the fifth item, Xixi's eyes were filled with a pleasant smile, she spread out her empty hands, and said with surprise and joy, "No more!"

"Is it the fifth paragraph?" Teacher Mu asked with a smile.

"It's five paragraphs! It's amazing!" Chen Shiyun shouted impatiently following a few children below.

Xixi also nodded, but she soon discovered something, the little girl pointed at the packaging rope on the blackboard and said, "But, teacher, this rope and this one are too short!"

Of course, the ones cut from the middle after folding are of different lengths, some are very long and some are very short.

"It doesn't matter, because our problem is, how can my mother cut it into five sections, not exactly five sections of the same length, so it's okay to cut it into five sections with only one cut." Teacher Mu faced Xixi. The observation ability is a bit of a headache, and it can only be explained in this way.

Why is it a knife and five sections?

Teacher Mu did not explain, but left a space for the children to think. She also gave each child a wrapping rope to study on their own small table, and after returning home, with the help of their parents , can the study be able to use other shearing times to cut into five?

...

In the afternoon, Yang Yi brought Xixi back, and the little girl couldn't wait to tell her father what she learned today.

"That's very good!" Yang Yi said with a smile, "Tonight, Dad will study with you, not just once or four times, but there are many possibilities in between. Moreover, let's see how to fold so as to be as possible as possible. Cut the rope into five pieces of about the same length with one knife."

"Okay, okay!" The little girl nodded eagerly.

However, at night, not only Yang Yi and Xixi were studying the rope, but Lan Xin also joined in.

Lanzhou Kai went to Wucheng County, Jinling City to help Yang Yi buy land. He was away from home for a long time on a business trip. Yang Yi had to help guide Lan Xin's study!

Of course, the two little girls got together, playing and learning, learning to play, and this interest was even stronger.

"You only need one knife to cut a watermelon, because the watermelon is relatively large, but for apples, you can cut the two halves with one knife, put the two halves together, and then cut them into four parts with one knife..." Yang Yi instructed the two When the little girl was playing with the folded rope, Murphy also watched with a smile on the side with a small scorpion in her arms.

"Sister, hurry up and learn, you have learned it. When my brother grows up, you can teach me, okay?" Murphy held Xiaojiao upright so that he could lean on his arms and sit on his own. in his arms, then shook the little guy's little hand, and said in the tone of the character of Xiaojiao.

When Xixi heard it, she raised her head, and shifted her gaze from the rope in her hand to her brother.

"Giggle, that Mama, am I my brother's teacher?" The little girl laughed happily and said with great interest.
