    數學小故事幾則小報素材有趣的

    時間:2015-10-11 11:16:29本文內容及圖片來源于讀者投稿,如有侵權請聯系xuexila888@qq.com 樂平 我要投稿

      一下是小編整理的幾則數學小故事,可以用來做數學報的素材!大家一起學習吧!

      動物中的數學“天才”

      蜜蜂蜂房是嚴格的六角柱狀體,它的一端是平整的六角形開口,另一端是封閉的六角菱錐形的底,由三個相同的菱形組成,組成底盤的菱形的鈍角為109度28分,所有的銳角為70度32分,這樣既堅固又省料,蜂房的巢壁厚0.073毫米,誤差極少。

      丹頂鶴總是成群結隊遷飛,而且排成“人”字開。“人”字形的角度是110度,更精確地計算還表明“人”字形夾角的一半——即每邊與鶴群前進方向的夾角為54度44分8秒!而金剛石結晶體的角度正好也是54度44分8秒!是巧合還是某種大自然的“默契?”

      蜘蛛結的“八卦”形網,是既復雜又美麗的八角形幾何圖案,人們即使用直尺和圓規也很難畫出像蜘蛛那樣勻稱的圖案。

      冬天,貓睡覺時總是把身體抱成一個球形,這其間也有數學,因為球形使身體的表面積最小,從而散發的熱量也最少。

      真正的數學“天才”是珊瑚蟲。珊瑚蟲在自己的身上記下“日歷”,它們每年在自己的體壁上“刻畫”出365條斑紋,顯然是一天“畫”一條。奇怪的是,古生物學業家發現3億5千萬年前的珊瑚蟲每年“畫”出400幅“水彩畫”。天文學家告訴我們,當時地球一天僅21.9小時,一年不是365天,而是400天。

      阿拉伯數字的由來

      小明是個喜歡問問題的孩子。有一天,他對0-9這幾個數字產生了興趣:為什么它們被稱為“阿拉伯數字”呢?

      于是他就去問他的當數學老師的媽媽:“0-9既然叫‘阿拉伯數字’,那么肯定是阿拉伯人發明的了,媽媽對嗎?”

      媽媽搖搖頭,說:“阿拉伯數字實際是印度人發明的。大約在1500年以前,印度人就已經用一種特殊的字來表示數目,這些字有10個,只要一筆兩筆就可以寫成。后來,由于各國之間的接觸,這些數字傳入阿拉伯,阿拉伯人覺得它們很簡單,于是在自己的國家開始廣泛使用并且把他傳到全歐洲。就這樣,它們慢慢地就成了我們今天使用的數字。因為阿拉伯人在傳播這種數字方面,起的作用很大,人們也就習慣了稱這種數字為‘阿拉伯數字’。”

      小明高興地說:“原來是這樣。媽媽,這可不可以叫做‘將錯就錯’呢?”小明和媽媽都笑了。

      兒歌比賽

      數學學校舉行兒歌比賽,大象老師做裁判。

      小猴聰聰第一個舉手。聰聰清了清嗓子,開始朗誦道:“進位加法我會算,數位對齊才能加。個位對齊個位加,滿十要向十位進。十位相加再加一,得數算得快又準。”

      聰聰剛剛說完,小狗佳佳興起手,說:“我的兒歌和聰聰的很相似。”大象老師說:“好!那我們聽聽你的兒歌。”佳佳大方地走上臺,朗誦道:“退位減法并不難,數位對齊才能減。個位數小不夠減,要向十位借個一。十位退一是一十,退了以后少個一。十位數字怎么減,十位退一再去減。”

      大家為他們的精彩表演鼓掌。大象老師說:“他們的兒歌主我們明白了進位加法和退位減法,所以,我們覺得他們兩個人都得冠軍,好不好?”大家同意老師的意見,高興的鼓掌祝賀他們倆。

      日記本引他走向成才路

      雅各布·伯努利是歐洲著名的數學家,他于1654年出生在瑞士的巴塞爾。

      從13歲開始,雅各布悄悄地寫起了日記,他把自己在學習中所取得的收獲及遇到的難題,統統記了下來。翻開他的日記,有閱讀書報雜志的體會,有與別人討論數學問題時得到的啟發,有解決數學難題突發的奇想……日記成了雅各布學習數學的問題集,解決問題的思路集、辦法集,研究數學問題的收獲集、成果集。

      雅各布對數學的執著追求,終于使他走上了研究數學的道路。他33歲就成為巴塞爾大學數學教授。

      小熊開店

      小熊不喜歡學習,。一天,它忽然覺得做生意挺有意思,于是在學校旁邊開了一個水果店。小兔和小猴是它的同學,它們商量好,要整整這個不愛上學的懶家伙。

      它們來到小熊的水果店。

      “桃子怎么賣呀?”小猴問。

      “第一筐里6元3公斤,第二筐里6元2公斤。”小熊說。

      小猴又說:“如果我從兩筐拿5公斤,就要付你12元,對嗎?”

      小熊點點頭。

      “那我全買下,既然5公斤12元,那60公斤就是12×12=144元,是不是?”小猴說。

      “正是,正是。”小熊講。

      于是小猴買了所有的桃子,付了錢,和小兔高興地走了。

      到了晚上,小熊結賬,怎么算怎么虧本。它想,除了小猴,沒有其他人來買過東西呀。第二天,小兔來找小熊,小熊把情況和小兔說了。小兔笑著說:“這都是因為你學習不好,我們來教訓你一下。”說完,就把少給的錢補給了小熊。

      小熊慚愧地低下了頭。從此以后,小熊每天上課都認真。它們三個成了好朋友。

      數學博士的“錯誤”

      時間王國的全體國民剛剛舉行完一次數學考試,時間博士邀請數學王國的對對博士來做閱卷指導。對對博士高興地拿起一份試卷,可是他越看越生氣,這是為什么呢?原來他在檢查試卷的時候,發現所有人的試題都做錯了,例如:

      7+6=1;6+6=0;3-7=8

      對對博士把問題反映給時間博士,時間博士看著試卷,笑著對他說:“博士,他們做的并沒有錯誤。因為在時間王國中晚上12點就是0點,所以6=6=0;7點鐘再過6小時是13點,也就是1點,即7+6=1;3-7就是表示3點鐘前7個小時是8點鐘”

      對對博士一拍腦袋,說:“對呀!哎,看來我這個博士還得繼續學習啊。”

      事故講完了,小朋友們,你認識鐘表嗎?你會計算時間嗎?讓我們一起來學習“時間”。

      在日常生活中,數學無處不在,比如說:買菜、賣菜、算多少錢……

      下面就是一個小故事,是一個數字之間的故事。

      有一天,數字卡片在一起吃午飯的時候,最小的一位說起話來了。

      0弟弟說:“我們大家伙兒,一起拍幾張合影吧,你們覺得怎么樣?”

      0的兄弟姐妹們一口齊聲的說:“好啊。”

      8哥哥說:“0弟弟的主意可真不錯,我就做一回好人吧,我老8供應照相機和膠卷,好吧?”

      老4說話了:“8哥,好是好,就是太麻煩了一點,到不如用我的數碼照相機,就這么定了吧。”

      于是,它們變忙了起來,終于+號幫它們拍好了,就立刻把數碼照相機送往沖印店,沖是沖好了,電腦姐姐身手想它們要錢,可它們到底誰付錢呢?它們一個個呆呆的望著對方,這是電腦姐姐說:“一共5元錢,你們一共十一個兄弟姐妹,平均一人付多少元錢?”

      在它們十一個人中,就數老六最聰明,這回它還是第一個算出了結果,你知道它是怎么算出來的嗎?
