Although said that is opportunistic truly can achieve some goals, but this is not this class teachers wants to teach to the child. Teacher Mu praised to observe careful Xixi in every way possible first, then has drawn a line on the small blackboard. 虽然说投机取巧确实能达成一些目的,不过这并不是这堂课老师们想要传授给孩子的。穆老师先夸奖一下观察细致入微的曦曦,然后在小黑板上画了一条线。 The small blackboard that Teacher Mu uses is the magnetic blackboard . Moreover the chalk is also the water-soluble dustless chalk, has the safeguard to the health comparison of children. 穆老师用的小黑板是磁性黑板,而且粉笔也是水溶性的无尘粉笔,对孩子们的健康比较有保障。 After seeing only Teacher Mu drew this long white line, with the children said: „We for example, this is the line that a mother must cut, is good?” 只见穆老师画完了这条长长的白线之后,跟小朋友们说道:“我们比如,这是一条妈妈要剪的线,好不好？” „Then the black eraser in Xixi, is the scissors in mother hand, we wipe off points words like this, even if has cut.” Teacher Mu gives Xixi the black eraser, teaches her to gesticulate, then encourages saying that „comes, Xixi, you try, looked that must cut many times to cut five, slow......” “然后曦曦手里的黑板擦,就是妈妈手里的剪刀,我们这样擦掉一点的话,就算是剪了开来。”穆老师将黑板擦递给曦曦,教她比划一下,接着鼓励道,“来,曦曦,你来试试,看要剪多少次才能剪成五段,慢一点哦……” Xixi most likes is this link, can coordinate the teacher to do „experiment” together, under the stand Luisa also has Yang Luoqi they are envying of face. 曦曦最喜欢的就是这个环节,可以配合老师一起做“实验”,看台下路薇莎还有杨珞琪她们都是一脸的羡慕。 Sees only little girl to take up the black eraser joyfully, following place that the teacher gesticulated a moment ago, has scratched one with the corner. 只见小姑娘欣然拿起黑板擦,顺着老师刚才比划的地方,用边角擦了一道。 „How many present is?” Teacher Mu asked. “现在是多少段？”穆老师问道。 „Two!” Xixi lifts the small head, replied quickly, this small issue may unable to stump intelligent Xixi. “两段！”曦曦抬起小脑袋,回答得很快,这点小问题可难不住聪明的曦曦。 „Continue, cuts stops to five again.” Teacher Mu encourages to say. “继续,剪到五段再停。”穆老师鼓励道。 Xixi comprehends quickly, she cuts the fourth time, then stopped, but little girl also has some scruple. 曦曦领悟得很快,她剪到第四下的时候,便停了下来,只是小姑娘还有一些迟疑。 „How many present is?” Teacher Mu asked. “现在是多少段？”穆老师问道。 Xixi then counted, only heard the little girl sound clearly such as the big bead bead to fall the jade plate, clear pleased several: „One, two, three, four and five......” 曦曦便数了起来,只听见小姑娘声音清脆如大珠小珠落玉盘般,清悦地数道:“一、二、三、四、五……” „Is five?” Teacher Mu smilingly was asking. “是不是五段？”穆老师笑眯眯地问着。 Under stage these children this times also unwilling lonely, cried out „five” competitively. 台下那些小朋友们这时候也不甘寂寞,争前恐后地叫起了“五段”。 Xixi also nodded, but after the little girl point ends, has hesitated, raised the question in heart: „But, Teacher, I have cut four times!” 曦曦也跟着点了点头,不过小姑娘点完头之后,又迟疑了一下,提出了心中的疑问:“可是,老师,我才剪了四次呢！” little girl felt that is puzzled and mysterious. 小姑娘对此感到困惑和神奇。 How to have cut four times? 怎么只是剪了四次？ Teacher Mu explained with a smile: „We usually give the children eat the fruit the time, if a watermelon must apportion two children, can cut a blade from the middle? Then if must apportion four children, after having cut a blade, but must to this two halves watermelons, cut a blade separately, altogether is three blades?” 穆老师笑着解释:“我们平时给小朋友们吃水果的时候,如果一个西瓜要分给两个小朋友,是不是要从中间切一刀？然后如果要分给四个小朋友,是不是切了一刀之后,还要对着这两半西瓜,分别切一刀,一共是三刀？” Usually Teacher Mu like this cuts watermelon, sometimes the greedy children will be being been blocking by Teacher Cai and Teacher Shen, flows the saliva to look at Teacher Mu to cut the watermelon by far, this little while, they responded quickly, was shouting responded. 平时穆老师都是这样切西瓜的,嘴馋的小朋友们有时候会被蔡老师、申老师拦着,远远地流着口水看穆老师切西瓜,这会儿,他们都反应很快,纷纷叫嚷着回应起来。 This has understood well, Teacher Mu then with cutting watermelon same truth, explained this scissors string uses four times to cut five principles. 这样就好理解了,穆老师接着用切西瓜一样道理,来解释了这个剪绳子用四次剪成五段的原理。 However, with other issues not too, the answer of this problem is open, does not have one! 不过,跟其他的问题不太一样,这道题的答案是开放性的,并非只有一个！ Teacher Mu also smilingly said: „Although uses four times to complete to cut five a string, for the economical strength and time-saving, the teacher only needs to cut one time to cut five a string.” 穆老师又笑眯眯地说道:“虽然用四次可以完成将一个绳子剪成五段,可是为了节省力气、节省时间,老师只需要剪一次就能将一条绳子剪成五段。” Only with scissors one time? 只用剪一次？ Responded the quick children „” to call, responded that the slightly slow child blurry was also looking at the teacher: „What was teacher saying?” 反应得快的小朋友们已经“哇”地叫起来,反应稍慢的小朋友还迷迷糊糊地望着老师:“老师在说什么呢？” Xixi belongs to the former, but she does not have „”, she thinks very surprised: Doesn't need to cut four times? Why did the teacher say the scissors one time? 曦曦属于前者,不过她没有“哇”,她觉得很惊讶:不是需要剪四次吗？为什么老师说剪一次就可以？ In little girl this moment mind has been full of intellectual curiosity, her bright and intelligent big eye is looking up to Teacher Mu, does not hate to wink, probably was waiting for that the time of Teacher Mu performance testimony miracle is the same! 小姑娘此刻脑海里充满了求知欲,她那双水汪汪的大眼睛仰望着穆老师,都舍不得眨,好像在等待穆老师上演见证奇迹的时刻一样！ Teacher Mu has not made Xixi return to own position, this little while, has put out a long red plastic packing rope, said with a smile: „Xixi, the teacher needs you to help teacher busy now.” 穆老师也没有让曦曦回到自己的位置上,她这会儿,真的拿出了一条长长的红色的塑料包装绳,笑着说道:“曦曦,老师现在需要你帮老师一个忙。” „Good!” little girl complies joyfully. “好呀！”小姑娘欣然答应。 Teacher Mu makes Xixi take packing rope to rebate twice, then grabs two to take in the hand. 穆老师让曦曦拿着包装绳对折两次,然后抓着两头拿在手里。 „Now teacher must cut from the middle!” Teacher Mu makes the Xixi side begin with the packing rope, her scissors do not use as far as possible to Xixi, can make other children see. “现在老师要从中间剪开！”穆老师让曦曦侧着手拿包装绳,这样尽量她的剪刀不用对着曦曦,也可以让其他小朋友看到。 But Xixi saw that the shining scissors are gesticulating between the two small hands, she cannot bear low voice said with Teacher Mu: „Teacher, I am afraid......” 可是曦曦看到明晃晃的剪刀在自己两个小手间比划着,她还是忍不住小声跟穆老师说道:“老师,我害怕……” „Do not fear that the teacher will be very careful.” The Teacher Mu gentle voice comforts Xixi. “别怕,老师会很小心的。”穆老师柔声安慰曦曦。 This little while, witnesses the time of miracle, Wang Xijun of most skin at this moment cannot attend to noisily, is looking at the Teacher Mu scissors anxiously. 这会儿,真的是见证奇迹的时刻,就连最皮的王希隽此刻也顾不上吵闹,紧张地望着穆老师的剪刀。 Scissors snap one has cut the packing rope in Xixi hand, Teacher Mu not anxiously speech, but very dangerous the sharp weapon to the child receives first scissors type, locks, pulls out a colorful magnetic post, lets the Xixi several last present many packing ropes. 剪刀咔嚓一下将曦曦手中的包装绳剪了开来,穆老师没急着说话,而是先将剪刀这种对小朋友来说很危险的利器收起来,锁好,才掏出一把五颜六色的磁贴,让曦曦数手上现在有多少段包装绳。 To let the result that other children see to count intuitively, Teacher Mu also makes the Xixi number end one then to hand over one to oneself, she will use the magnet to pack the belt to paste on the magnetic blackboard. 为了更加直观地让其他小朋友看到数数的结果,穆老师还让曦曦数完一条便递一条给自己,她用磁铁将包装带贴在磁性黑板上。 „One, two and three......” Xixi was reading, but was not her alone in the number, other children also excitedly with shouting. “一、二、三……”曦曦念着,不过不是她一个人在数,其他小朋友也兴奋地跟着喊着。 Probably they are also hoping miracle is the same! 好像他们也在期盼着奇迹一样！ Finally counts to fifth, the Xixi eye is having the pleasantly surprised happy expression, has spread the air-to-air small hand, happily said with amazement and also: „Did not have!” 最后数到第五条,曦曦眼睛带着惊喜的笑意,摊了摊空空的小手,又惊讶、又高兴地说道:“没有了呢！” „Is five?” Teacher Mu smilingly asked. “是不是五段？”穆老师笑眯眯地问道。 „Is five! Amazing!” Chen Shiyun below, called out with several children impatiently. “是五段！好厉害啊！”陈诗云在下面,跟着几个小朋友迫不及待地叫道。 Xixi also nods, but, she had discovered quickly also a matter, little girl points at the packing rope on blackboard saying: „But, Teacher, string, had this to be too short!” 曦曦也点头,不过,她很快也发现了一个事情,小姑娘指着黑板上的包装绳说道:“可是,老师,绳子这个、还有这个太短了！” After the fold, cuts from the middle is the length varies certainly, some are very long, some are very short. 折叠后从中间剪开的当然是长短不一,有的很长,有的很短。 „Has not related, because our issues are, how mother can cut five, does not want exactly the same long five, therefore only one time can cut five with the scissors, is.” Teacher Mu is facing Xixi some observation capability headaches, can only explain like this. “没关系,因为我们的问题是,妈妈如何才能剪成五段,并不是要一模一样长的五段,所以只用剪一次就能剪成五段,还是可以的。”穆老师面对着曦曦的观察能力有些头疼,只能这样解释。 Why can be blade five? 为什么会是一刀五段呢？ Teacher Mu had not explained that but has left a space of ponder to the children, she has given back to each child packing rope, making them study on own small table, after as well as goes back, with the help of father and mother, the research can cut five with other cutting? 穆老师却没有解释,而是给小朋友们留下了一个思考的空间,她还给了每个小朋友一条包装绳,让他们在自己的小桌子上研究,以及回去后,在爸爸妈妈的帮助下,研究能不能用其他的剪切次数来剪成五条？ ...... …… In the afternoon, Yang Yi meets Xixi, little girl then impatiently told the new knowledge that the father learns today. 下午,杨轶将曦曦接回来,小姑娘便迫不及待地告诉爸爸今天学到的新知识。 „This is very good!” Yang Yi said with a smile that „the tonight's father studies with you together, not only one or four times, among this have many possibilities.
