Although opportunism can achieve some goals, this is not what teachers want to teach children in this class. Mr. Mu praised his meticulous observation and drew a line on the small blackboard.

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

After Mu finished drawing the long white line, he said to the children, "let's say, this is a line that my mother wants to cut, OK?"

"Then the blackboard eraser in Xi Xi Xi's hand is the scissors in her mother's hand. If we erase a little bit like this, we will even cut it open." Teacher Mu handed the blackboard eraser to Xi Xi Xi, taught her to draw, and then encouraged her, "come on, Xi Xi, let's see how many times it takes to cut it into five segments. Slow down..."

Xixi's favorite part is this link. She can cooperate with her teacher to do "experiment". Lu Weisha and Yang LUOQI are all envious.

I saw the little girl happily picked up the blackboard eraser, along the teacher's place just now, with the corner wipe.

"How many paragraphs are there now?" Mr. Mu asked.

"Two paragraphs!" It's hard to answer a small question.

"Go on, cut to five and stop." Mu encouraged.

Xi Xi understood very quickly, when she cut to the fourth, she stopped, but the little girl still had some hesitation.

"How many paragraphs are there now?" Mr. Mu asked.

Xi Xi then counted up, only heard the little girl's voice clear and crisp, like a big pearl and a small pearl falling on a jade plate. She said, "one, two, three, four, five..."

"Is it five paragraphs?" Mu asked with a smile.

The children under the stage were not willing to be lonely at this time, and scrambled to call up "five sections".

Xi Xi also followed and nodded, but after the little girl nodded her head, she hesitated for a moment, and raised the question in her heart: "but, teacher, I just cut it four times!"

The little girl was puzzled and magical about it.

Why did you just cut it four times?

Mu explained with a smile: "when we usually give the children fruits, if a watermelon is to be distributed to two children, is it necessary to cut a knife from the middle? Then, if you want to give it to four children, do you have to cut the two halves of the watermelon after one knife? It's three knives in total? "

Usually, Mr. Mu cuts watermelons like this. Sometimes greedy children are stopped by Mr. Cai and Mr. Shen, drooling from afar to watch Mr. Mu cut watermelons. At this moment, they all respond quickly and shout in response.

It's easy to understand. Mr. Mu then explained the principle of cutting the rope into five sections by cutting it four times.

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

To save time, the teacher said, "it takes five times to cut the rope into five pieces."

Just one cut?

Quick reaction of the children have been "wow" to call out, a little slower reaction of the children are still vaguely looking at the teacher: "what is the teacher saying?"

Xixi belongs to the former, but she doesn't have "wow". She is surprised: don't you need to cut it four times? Why does the teacher say it's OK to cut it once?

At the moment, the little girl's mind is full of curiosity. Her big watery eyes are looking up at Mr. mu. They are reluctant to blink, as if they are waiting for teacher Mu to witness a miracle!

Teacher Mu didn't let Xi Xi Xi return to her position. She took out a long red plastic packing rope and said with a smile, "Xi Xi Xi, the teacher needs you to help the teacher now."

"Good!" The little girl readily agreed.

Teacher Mu asked Xi Xi Xi to fold the packing rope in half twice and then hold both ends in her hand.

"Now the teacher wants to cut it in the middle!" Teacher Mu asked Xi Xi Xi to hold the packing rope on her side so that her scissors could be seen by other children without facing Xi Xi Xi.

However, Xi Xi Xi saw the bright scissors gesticulating between her two small hands. She couldn't help but whisper to teacher Mu: "teacher, I'm afraid..."

"Don't be afraid. The teacher will be very careful." Teacher Mu gently comforts Xi Xi.

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

The scissors snapped and cut the packaging rope in Xi Xi's hand. Instead of speaking in a hurry, Mr. Mu put away the scissors, which is very dangerous for children, and locked it. Then he took out a colorful magnetic tape and asked Xi Xi to count the number of pieces of packaging rope in his hand.

In order to let other children see the counting results more intuitively, Mu also asked Xi Xi Xi to hand out one to herself after counting. She used a magnet to stick the packing tape on the magnetic blackboard.

"One, two, three..." Xi Xi read, but she is not alone in the number, other children are also excited to follow the call.As if they were looking forward to a miracle!

Finally count to the fifth, Xi Xi Xi eyes with a surprise smile, spread out the empty hands, and surprised, and happy to say: "no more!"

"Is it five paragraphs?" Teacher Mu asked with a smile.

"It's five! How wonderful Chen Shiyun in the following, followed by a few children can't wait to call.

Xi Xi also nodded, but she soon found something. The little girl pointed to the packaging rope on the blackboard and said, "but, teacher, the rope and this are too short!"

After folding, cut from the middle is of course different length, some very long, some very short.

"never mind, because as like as two peas, we have to cut five segments, not five segments, so we can cut five segments by cutting them once, and we can still do that." Teacher Mu has a headache in the face of Xi Xi's observation ability, so she can only explain it in this way.

Why is it a knife with five segments?

Mu did not explain, but left a space for the children to think. She also gave each child a piece of packing rope to study on their own small table. After returning, with the help of their parents, she studied whether they could cut five pieces with other cutting times?

……

In the afternoon, Yang Yi will Xi Xi Xi back, the little girl can't wait to tell her father today's new knowledge.

"That's good!" Yang Yi said with a smile, "my father will study with you tonight, not only once or four times, but there are many possibilities. What's more, let's look at how to fold it so that we can cut the rope into five pieces of almost the length with one knife as much as possible. "

"Yes, yes!" The little girl nodded longingly.

However, in the evening, not only Yang Yi and Xi Xi are studying the rope, but also Lan Xin.

Lanzhou Kai went to Wucheng County of Jinling City to help Yang Yi buy land. She was not at home for a long time on business. Yang Yide helped guide Lanxin's study!

Of course, two little girls get together to play, learn to play, this interest is more intense.

"It takes only one knife to cut a watermelon, because the watermelon is relatively large, but if you cut an apple, you can cut it in half with one knife, and then you can cut it into four pieces with another knife." When Yang Yi instructs the two girls to play with the folding rope, Murphy also holds the small bamboo and looks at it with a smile.

"Sister, you learn quickly and learn it. When my brother grows up, you can teach me, OK?" Murphy held the little mango upright, so that he could rely on his own arms to sit in his arms, and then shook the little guy's little hand, and said in the tone of Xiaozhuo's role.

Xi Xi heard, she raised her small head, the line of sight from the hands of the rope, moved to the younger brother.

"Cluck, Ma Ma, am I my brother's teacher?" The little girl was so happy that she said with great interest.
