于是比利就到学校四处向同学搜集,终于在赠奖截止前搜集到71个外包装。
请问比利总共可以换到多少块免费的巧克力
消失的直线
在一张纸上仔细画出12条直线,每条线长3cm,间距2cm,如图1所示。
然后将第一条线顶端和最后一条线末端连成直线,沿此线将这张纸裁成两张。
现在沿着切开的边缘,如图2所示移动这两张纸,使直线重合。
现在纸上有几条直线?你如何解释其中的矛盾?
火柴棒正方形
从如图排列的15根火柴棒中移去3根,使得只留下3个正方形.从如图的15根火柴棒中移去2根,使之成为3个正方形.(正方形的大小不必相同.)
渡河问题
这是个老掉牙的谜题.故事是一个卖艺人到乡下旅行,带着一只狼、一只羊与一棵包心菜.走到河边,发现只有一只小船,每次只能随身带一只狼,或一只羊,或一棵包心菜渡河.
可是他不敢让狼与羊单独在一起,或是让羊与包心菜单独在起,因为狼会吃掉羊,羊会吃掉包心菜.经过一番思考,他想出办法,用小船把自己以及所有的财产都安全运到对岸.他是如何做到的?
聪明的牛奶商
一位牛奶商只有容量为5升与3升的两个瓶子,可供他从牛奶罐中量取客户所需的牛奶.
请问如何量出1升牛奶,而且不得浪费任何牛奶?
聪明的园丁
一位园丁想要充分利用他的植物.有一天,当他在设计攻瑰花床时,他发现可以种植7丛玫瑰,其中每3丛玫瑰排成一列,总共有6列.请问他是如何做到的?
园丁非常得意,想找出其他的组合方法.后来他发现还可以种植10丛玫瑰,每4丛玫瑰排成一列,总共有5列.
思考时间
(1)在3点12分时,时钟的长短针所夹的角度是多少?
(2)在每一个小时中,时针与分针会在某一点重合,当时针与分针在7与8之间重合时,此时的精确时间是多少?
生日巧合
阿雷博士是一所大型综合中学的校长,他注意到在所有班级中有一半以上的班,其班上至少有两个学生的生日是同一天.他认为既然一年是365天,所以只有在一个班上是366个学生时,才一定会有两个学生的生日相同.
他知道学校中平均每班有30个学生,所以他以为生日相同的学生数应该是项纪录.爱出风头的他预备将此纪录发给各报社,以及《吉尼斯纪录大全》.幸好他的同事安姬在听到他的打算后及时阻止,才没闹笑话.安姬告诉他,这种生日巧合并不足以为奇.她的理由何在?在一个有30名学生的班级中,至少有两个人生日相同的概率是多少?
60°角折叠法
要折出180°、90°、45°与22.5°角并不困难,因为这只需要反复对分一个角,可参见第3题.但要得到60°或30°角,却需要三等分一个角.其实这也可以很轻松地做到,参见图1.取一张长方形纸,将AB折至DC,作出一条等分这张纸的折线MN;再折纸使折线通过D,且A在折线MN上.此时AD与DC的夹角为30°,而折线LD与DC的夹角为60°.
如图2,如果再将纸通过L点而折至与BC平行,然后先不把纸打开,沿LD折叠,就可以折出等边三角形,如图3中的三角形LPD.
运用已有的折线,很容易折出或画出其他的直线而作出一系列的等腰三角形,或是一些立体形状的展开图(图4).
圆的半径
长方形ABCO的一个顶点位于圆心O,另一个顶点A距离圆周2cm。A与C的距离为7cm。
圆的半径是多少?
勾股定理再探
勾股定理证明方法之一的培利加剖分(Perigal’s dissection)在《数学乐园·茅塞顿开》中已经描述过,但因为勾股定理是相当重要的定理,故在此再特别举出一些可行的证明方法,供读者做比较.
下面列举的前3个方法非常类似,而且都需要利用到4个全等的直角三角形.请将它们从卡片中剪下,并且实际练习看看.
(1)如图1所示,将4个三角形排成边长为a+b的正方形4BCD,使中间留下边长c的一个正方形洞(阴影部分).
画出正方形ABCD.现在移动三角形至图2所示的位置中,于是留下了边长分别为a与b的两个正方形洞.这么一来,图1和图2中的阴影部分面积必定相等,所以
c2=a2+b2
(2)此证明以图1为基础:
正方形ABCD的面积=阴影部分正方形的面积+4个三角形的面积
得出 a2+b2=c2
(3)这次将4个直角三角形的直角部分朝内放,排成一个边长为c的正方形PQRS(见图3),中间的洞(阴影部分)则是边长为b-a的正方形.
正方形PQRS的面积=阴影部分正方形的面积+4个三角形的面积
得出 c2=a2+b2
(4)此证明于1860年首次发表,同样也是着眼于使面积相等的概念.这题与上述的第一、第二个方法有颇多类似之处.
正方形ABNL的面积
=正方形KCOM的面积-4个三角形的面积
=正方形DFHI的面积-4个三角形的面积
=正方形DFHI的面积-长方形ACBI的面积-长方形CEFC的面积
=正方形ADEC的面积+正方形BCGH的面积故可得
c2=b2+a2
(5)介绍了许多几何变换的方法后,这里要以有趣的切变换(shearing transformation)为基础来证明勾股定理.参见图 5.
将以BC为边的正方形斜切至右方,并将以AC为边的正方形向上切至与直线CD相连.(要记住,切变换使面积保持不变.)然后再将图形沿直线DC切换,直到图形抵达直线AB为止,这时图形变成正方形ABEF.
以AB为边的正方形面积=以BC为边的正方形面积+以AC为边的正方形面积
所以 c2=a2+b2
(6)此证明有时会利用相似三角形来解释,但参考图6用三角函数来证明会更容易些.
AB=AN+NB c=b cosθ+a cosφ
将上式等号两边同时乘以c,则得
c2=b2+a2
(7)勾股定理最令人满意的证明之一就是用向量来证明,参见图7所示.
c2=c·c=(a+b)·(a+b)=a·a+2a·b+b·b=a2+b2
因为 a⊥b
所以a·b=0
趣味数学教案 篇2
给数字一个生命
小朋友们,当你轻轻地打开数学书的时候,是否看到了数字们微笑的脸?咦?数字怎么是活着的呢?当然是活着的喽!他们各有不同的性格。你看,一向认为自己个头最高、腰板总是挺得直直的“1”,是多么傲慢呀。他可以整除所有的数,但是他除了自身之外却不能被别的数整除,真可谓是“独霸将军”。
但是“2”却很和善,所以他和他的倍数们成了很好的朋友。听说过什么是质数吗?那些家伙在数字界中有点与众不同。他们很固执,相互缠在一起,挂在筛子上怎么都打不散,总是抱成团。怎么样,数字们都拥有不同的个性吧。因此,我们不能忽视他们的生命。据说,数字们也时常组织聚会呢。这种聚会根据不同的目的和时间而定,同样的数字可以参加不同种类的聚会。当听到“自然数集合”时,所有的自然数就会聚集在一起,但是当听到“整数集合”时,刚刚集合在自然数队伍里的数字们就会跟着整数的队伍走。趣味数学题
1个大西瓜 vs.3个小西瓜
去年夏天某日,一个卖西瓜的人在不停地叫喊着:“1个大西瓜10元钱,买3个小的也是10元钱。”这时过来一位细心的顾客,他拿了两种西瓜,目测大西瓜直径约8寸,小西瓜直径约5寸。
可是他也犯了难,到底买哪种更合算呢?
让我们来帮帮他吧!
首先,我们从体积上来比一比,球的体积公式是4/3πr3,或1/6πD3。r是半径,D是直径。
求它们体积比时,可省去1/6和π。因此,大西瓜体积∶3个小西瓜体积之和
=[8×8×8]∶[(5×5×5)×3]
=512∶375 由此可见,买3个小西瓜是很吃亏的。

外婆家的电话分机号码是四位数,记不清是多少,只记得它没有重复数字,并且能同时被1、2、3、4、5、6、7、8、9整除。这个号码究竟是多少呢?
从条件知道,外婆家的电话分机号码是九个数1、2、3、4、5、6、7、8、9的一个公倍数。
这九个数的最小公倍数是:
8×9×5×7=2520.2520是四位数,但是有重复数字(2出现两次),不合条件。
四位数中,还有两个是2520的倍数,它们分别是5040和7560,其中只有7560不含重复数字。因而所求的电话分机号码是7560.笑话——轻松一刻 差别在此
方老师在数学课上问阿细:“一半和十六分之八有何分别?”阿细没有回答。方老师说:“想一想,如果要你选择半个橙和八块十六分之一的橙子,你要哪一样?”阿细:“我一定要一半。”“为什么?”“橙子在分成十六分之一时已流去很多橙汁了,老师你说是不是?”
两个饭桶
某大队小学女老师讲课。头一节课教“1+1等于几?”讲了很久,孩子们都没听懂.她就就叫一名男孩站上来,问:“一个中国加一个湖南等于几?”男孩莫名其妙答不出来。女教师操起教鞭狠敲讲台,提高声音:“1根教鞭加1张讲台等于几?” 男孩依旧答不出。此时女教师用教鞭敲了他的脑壳一下:“饭桶,我加你等于几 啊?”男孩立时醒悟了,道:“两个饭桶。”
数阵
1、△、□、〇分别代表三个不同的数,并且:
△+△+△=〇+〇;〇+〇+〇+〇=□+□+□; △+〇+〇+□=60
求:△= 〇= □=
2.将九个连续自然数填入3行3列的九个空格中,使每一横行及每一竖列的三个数之和都等于60.3.将从1开始的九个连续奇数填入3行3列的九个空格中,使每一横行、每一竖列及两条对角线上的三个数之和都相等.用1至9这9个数编制一个三阶幻方,写出所有可能的结果。所谓幻方是指在正方形的方格表的每个方格内填入不同的数,使得每行、每列和两条对角线上的各数之和相等;而阶数是指每行、每列所包含的方格的数。
一、解:因为△+△+△=〇+〇 所以○:△=2:3=4:6 因为〇+〇+〇+〇=□+□+□ 所以○:□=4:3 因上△:□=2:1=6:3 所以○:△:□=4:6:3 因为△+〇+〇+□=60 所以△=6*60/6+4+4+3=360/17 □=3*60/6+4+4+3=180/17 ○=4*60/6+4+4+3=240/17
二、设九宫格的中间数是X 再借助口诀: 二四为肩,六八为足; 上九下一,左七右三。五在中。所以这九个数是 X-3 X+4 X-1 X+2 X X-2 X+1 X-4 X+3 因为每行每列的三数之和等于60,也等于3X 所以X=20,九宫格是 17 24 19 22 20 18 21 16 23
三、由题知这九个数是 1、3、5、7、9、11、13、15、17 再根据口诀:
趣味数学教案 篇3
引导学生通过常规分析,得出解题思路,经历提出问题,自探问题,应用知识的过程,自主总结出解题办法;
【教学难点】
找出题目中的`可有可无的已知条件,说一说为什么可以这样认为
【教学过程】
问:以前学过的有关路程,时间,和速度之间的关系是怎么样的?你能写出它们之间的关系吗?
出示例题:甲、乙两地公路全长352千米。汽车原来从甲地到乙地要11小时,建成高速公路后,汽车每小时速度是原来的2.5倍。现在汽车从甲地到乙地需要多少小时?
分析:要求现在汽车从甲地到乙地需要多少小时,那么先要求出汽车现在的速度,而汽车现在的速度是原来的2.5倍,那么还得先求出汽车原来的速度。根据`甲乙两地公路全长352千米。汽车原来从甲地到乙要11小时,可以求出汽车原来的速度。
学生写出解答过程:汽车原来的速度:352÷1=32(千米);汽车现在的速度:32×2.5=80(千米)
现在的时间:352÷80=4.4(小时)
问:用比例的思路该怎么样理解这道题目呢?
分析:甲、乙两地的公路长度一定,汽车的速度和所需的时间成反比例。因为现在的速度是原来的2.5倍,所以原来的时间是现在的
2.5倍。即:11÷2.5=4.4(小时)。
这样解答使得`甲乙两地公路全长352千米成了多余条件,但是又不影响解答问题。
【我们来探索】
一批零件有240个,王师傅单独做需要6小时,李师傅的工作效率是王师傅的1.5倍,那么如果让李师傅单独做这批零件,需要几小时?
【总结】
在解答应用题时要善于应用不同的思路和技巧,巧解问题
【作业】
丁阿姨打一份稿件需4小时,王阿姨的速度是丁阿姨的,那么如果由王阿姨打这份稿件,需要几小时?

三下乡趣味数学教案 篇6
三 下 乡 支 教
杨晓杰 机械三班
2016年6月19日
第一节 一笔画
一、自我介绍
大家好,我叫杨晓杰,是黑龙江大学机电工程学院的一名大一新生。大家听说过大学吗?这是一个非常好玩的地方,在这里你可以学到很多东西,也可以认识很多跟你不同年级的小伙伴。大家长大了想去大学吗?那又不想去大学的吗?那你们的梦想是什么呀?很高兴能来到这里,教你们这么可爱的小朋友们,希望在以后的几天里我能与大家成为好朋友。
二、引出趣味数学题
大家学过数学吗?那大家都是从一上小学就开始学数学的吧?大家数学学的好吗?好,这几天我要教大家的是趣味数学,看看标题大家不要害怕,它是数学,但它是非常有意思的数学,大家想学吗?那就让我们开始今天的学习吧。
三、引出一笔画
在数学中大家看到过这些图形吗?那位同学给我说一下这些图里都有什么形状呀?那大家试一试怎么才能不这些形状画出来呢?那大家再试试能不能把这些形状用一笔画出来呢?这就是今天要带大家玩的,就是用一笔画出一个形状。(拿出几个形状,让同学们讨论,互相研究)好,我看有的小组有的小朋友画出来了,没画出来的小朋友想知道是怎么画的吗?哪位小朋友想告诉大家呀,达上来的有奖励哟!
四、介绍一笔画
早在18世纪,瑞士的著名科学家欧拉就找到了一笔画的规律。欧拉认为,能一笔画出的图形必须是连通图。连通图就是指一个图形各部分总有相连的。但并不是所有的连通图都可以一笔画的。能否一笔画是由图的奇、偶点的数目来决定的。
(1)凡是由偶点组成的连通图,一定可以一笔画成。画时可以把任意一偶点当起点,最后一定以这个点为终点画完此图。
(2)凡是只有两个奇点的连通图(其余都是偶点),一定可以一笔画成。画时必须把一个奇点为起点,另一个奇点为终点。
(3)其他情况的图都不能一笔画出。(有偶数个奇点除以二便可算出此图需要几笔画出。)
五、课后作业
第二节 逻辑推理

3、能用语言表述相关的操作内容,愉快地参加活动。
4、提高逻辑推理能力,养成有序做事的好习惯。
5、提高数数的兴趣和积极思维的能力。
活动准备:
白板课件。
活动过程:
1、认识怪兽导入活动。
展示怪兽和数字。
教师:这些怪兽真奇怪,他们的身上有好多的点点,让我们来看看这些点子跟中间的数字有什么关系呢?
2、吃数字的怪兽。
根据怪兽身上的点数吃相应的数字。
3、根据骰子的点数记录数字。
请3~4位幼儿到教师机上操作点击骰子滚出一个数字。
使用荧光笔在怪物身上来标记相应的数字。
4、游戏幼儿分组操作组一:记录记录怪物身上的点数。数出怪物身上的点数,在方框里写出点数。
组二:按照怪物身上的图案搭配相应的图案1。
组三:按照怪物身上的图案搭配相应的图案2。
组四:把怪物送回家
5、看课件检查答案。
教学反思:
幼儿园的数学活动相对于其他活动枯燥、单调,容易使幼儿失去学习兴趣。因为这个时期的幼儿年龄小,逻辑思维尚未发展,所以本次活动中我为幼儿创设了一个可操作的丰富材料的环境,为幼儿创设了一个可选择性、可操作性的空间。使幼儿能独立的操作材料,并大胆的表达自己的想法。幼儿的自主性,选择性,独立性得到了充分的体现。通过一系列的游戏活动,达到了主题总目标预设的要求。
