 3参观学校——比较大小与近似数

教学内容

教材第2425页,比较数的大小与近似数。

教学提示

由于有了前面的知识基础,本课在提供情境后应放手让学生探究,自己得出方法。教材借学生之口,提示了多种方法,有找一个中间数与之比较,数位比较,由高位往低位相同数位逐位比较,看近似数比较等,体现解决问题策略的多样化,以便于培养学生对已有知识灵活运用的能力和创新能力。

把近似数的相关知识,融入到比较数的大小中,通过举例描述近似数的含义,帮助学生体会到近似数在生活中有着广泛的运用。

教学目标

知识与能力

1、熟练比较数的大小,并会用语言和符号描述万以内数的大小比较。

2、知道近似数的含义,会求近似数。 

过程与方法

通过观察、讨论、交流、抽象、概括等数学活动,发展学生的抽象思维。

情感、态度与价值观

1、让学生感受数学与生活的联系,体会数学的意义和作用,激发学习数学的乐趣。

2、让学生逐步养成做事耐心细致的好习惯。

教学重点、难点

教学重点:比较万以内数的大小,会运用近似数。

教学难点:用语言和符号描述比较万以内数的大小的方法

教学准备

教师准备:课件 

学生准备:计数器

教学过程

(一)新课导入:

1、谈话小朋友到北京参观学校,受到热烈欢迎,还参观了餐厅和图书馆,我们去看一下。

2、观看视频(课件出示)

3、课件出情境图,你发现了哪些数学信息?

信息有:(1)光明小学有1210人,实验小学有958

2)一楼餐厅597座,二楼餐厅508

3)故事书895册,科技书806

4、根据这些信息,你想提出哪些问题?

生:一楼餐厅大约能坐多少人?

生:哪个学校的人多?

生哪种数多一些?

5、我们先来看一下第一个问题

设计意图: 以动画的形式,调动学生的积极性,引发孩子们的兴趣,创设愉悦的学习氛围。

(二)探究新知

1、解决问题一:一楼餐厅大约能坐多少人呢?二楼呢?

1)齐读问题,找到数据

2)同桌讨论597大约是多少,508大约是多少

3)交流

生:5975个百,9个十和7个一组成,比6003个,597接近600

生:5085个百和8个一组成,比5008个,508接近500

4)课件出示数轴

看来同学们理解的非常好,大约是多少,也就是最接近哪个数

这时候我们就说600597的近似数,597600,同样500508的近似数,508500

5600597的近似数,还能是谁的近似数?

生:601

生:605

610

生:598

生:595

生:……

500508的近似数,还能是谁的近似数?

生:501

生:499

生:498

生:505

生:……

6)研究1210,958,895,806他们的近似数是多少

生:1210的近似数是1200

生:958的近似数是1000

生:895的近似数是900

生:806的近似数是800

再一次补充89的近似数是

生:90

7)生活中我们有时候我们不需要准确数,用近似数就可以,近似数一般是接近原数的整十数、整百数、或整千数。

设计意图:学生根据数的组成,能够自己独立找到近似数,教师再用课件出示数轴方法,演示学生的思考过程,向学生证明自己的思考是对的,教师一个问题600597的近似数,还是谁的近似数?将学生的思考推向了另一个思考高度,有些数的近似数是同一个数。后面的巩固练习拓展了近似数的范围,整十数、整百数、或整千数。

2、哪所学校的人数多?已经有了除法竖式的知识储备,所以这时放手先让学生自己写,(1)下面我们看一下第二个问题(齐读)

2)这个问题也就是

生:比较1210958的大小

3)画一画,拨一拨小组内研究一下这两数的大小

4)汇报交流

 

;1210接近1200,958接近10001210958,9581210

生:1210由一个千,2个百1一个十组成,9589个百,5个十和8个一。1210958,9581210

生:1210有千位,958没有千位,1210958,9581210

生:四位数大于三位数

5)巩固练习

78451          100009999

生:451是三位数,78是两位数,45178,78451.

生:10000是五位数,9999是四位数,100009999,999910000.

6)总结一位数<两位数<三位数<四位数<五位数,数位多,这个数就大。

3、故事书和科技书,哪类册数多?

1895接近900,806接近800,895806,806895

2)都有8个百,8959个十,806十位上没有895806,806895

 3)总结,数位不同,先看最高位,相同再看下一位,直到比出大小为止。  

设计意图:比较的数的大小,有多种方法,只要学生说的合理,描述正确,都是好方法,教师帮忙整理常用的方法,学生对比之后自己就会优先选择最快的方法。 

(三)巩固新知:

1、说出下面数的近似数

307      987        1506

生:307接近300所以307的近似数是300

生:987最接近1000,所以987的近似数是1000

生:1506最接近1500,所以1506的近似数是1500    

2、我会比较数的大小

60909060      892899              6280628

生:最高上69,所以60909060

生:最高位上数字一样,十位上数字也一样,个位上29,所以892899

生:三位数<四位数所以6280628

设计意图:通过再一次练习,检查学生对近似数的理解,在进行数的大小比较时,一定让学生多说自己的比较方法,比较数位。 

(四)达标反馈

一、填空:

1. 读数和写数,都要从(  )位起.

2. 一个数千位上是1,个位上是6,这个数是(  )

3. 99899991中间的数是(  )

4. 10个一是(  ) 10(  )是一百. (  )个一百是一千. 一万里面有(  )个一千.

5.9个千、6个一组成的数写作:_________读作:______________

二、按要求排列下面各数.

9101   9100   9001  9110

(  )(  )(  )(  )

   答案:一题:高,1006,9990,10、十、1010,9006,读作:九千零六

二题:9001,9100,9101,9110        

(五)课堂小结

这节课你的收获是什么?哪些方面你对自己很满意?

生:我知道了近似数

生:我学会比较万以内数的大小

生:有的数的近似数相同 

生:在刚才发言时我受到了你的表扬。

设计意图:这一环节,是教师和学生一起进行总结的过程,使学生学会总结知识,把所学知识变成自己内在的东西。自己对自己的及时评价,使得孩子们发现自己的优点,培养孩子的自信和对数学学习的兴趣。

(六)布置作业

一、 判断题

1. 6000里面有60个十.                 (  )

2. 个位上的8、十位上的8、百位上的8、千位上的8,意思相同。    

3. 990起,一十一十地数,数到第三个数是1020     (  )

4. 7个一、3个十、6个百、4个千组成的数是7364     (  )

二、写出下面各数的近似数

698               2956             3120            2802

三、在□里填上合适的数.

825891         59362  

四、写一写,比一比。

数不相同的数大小比较,如果位数相同的两个数你们会比较吗?比如:895806,(请大家相互讨论,学生讨论,师巡视并引导他们)

师:谁来说一说,你是怎样比较的?

1:比位数,位数多的就大,位数少的就小

2:这道题不能这样比较,因为他们都是三位数,

3 我认为应该比较他们的最高位,895”这个数的最高位上的数是“8”,表示8个百,806”这个数的最高位的数是“8”表示8个百,

师:最高位相同,怎么办?

生:如果百位的数相同,就比较十位,895”这个数的十位上是“9”表示9个十,806”这个数的十位上的数是“0”表示0个十,9个十显然比0个十要多,所以895”比“806”要大。

师:回答得很好,来一点掌声,好吗?

师:如果十位上的数也相同呢?怎样比较?

生:照样比较下一位, 

师:这个题的下一位是哪一位。

生:个位。

师:同学们,真的聪明。

(由学生说,师板书:首先比较两个数的位数,位数多的数就大;如果位数相同,就比较两个数的最高位,最高位上的数大那个数就大,如果最高位上的数相同,就比较下一位,依次类推)

数学符号的故事

很久很久以前,数学王国里乱糟糟的,没有任何秩序。0~9十个兄弟不仅在王国中称王称霸,而且他们彼此之间总是吹嘘自己的本领最大。数字天使看见这种情况很生气,于是就派“>”、“<”和“=”三个小天使到数学王国,要求他们一定要让王国变得有秩序起来。

三个小天使来到了数学王国,0~9十兄弟轻蔑地盯着他们,9”问道:“你们三个是干什么的?我们的王国不欢迎你们。” 

=”天使笑了笑说:“我们是天使派到你们王国的法官,帮助你们治理好你们的国家。我是‘等号’在我两边的数字总是相等的;这两位是‘大于号’和‘小于号’他们开口朝谁,谁就大,尖尖朝谁,谁就小。”

0~9十兄弟一听他们是数字天使派来的法官,以及=”的介绍,都乖乖地服从“>”、“<”和“=”的命令。 从此以后,数学王国越来越强盛,而且有着十分严格的秩序,任何人都不会违反。

      本平台采用的是类似淘宝的担保交易形式,整个交易过程由平台进行担保,买家付款后钱款进入平台账户,买家收到宝贝确认无误后,平台打款到商家账户,确保整个交易流程公正。


资料默认是以百度网盘链接的形式自动发送,付款后立马即可收到,无需等待。


退款情形:

 

一、实际资料与宝贝详情描述不符的:

(1)版本信息不符,如:宝贝描述显示是人教版,结果收到的链接是其他版本的;

(2)资料与现行教材不配套的,如:宝贝详情里标明为最新资料,实际为旧版资料的;

(3)收到的资料宝贝详情所列资料不同,挂羊头卖狗肉的;

(4)宝贝详情里标明有的资料实际没有或者资料缺失不完整的;

(5)资料整理乱、差、重复、缺失的;

注:个别版本的资料及其稀缺,暂时无法保证完整的,需在宝贝详情里标明,否则责任归咎于商家。


二、商家拒绝履行售后服务的:

(1)收到资料无法打开,或打开为乱码的,商家不协助解决的;

(2)资料中个别文档无法正常使用,商家不予替换或修复的;

(3)资料在下载过程中出现问题,商家拒绝指导的;

      (4)商家未履行相关承诺的;

注:有时咨询就多,为节约您的时间,常见问题可以自行解决:资料打不开?95%都是因为:①您没有安装解压软件,点此下载安装解压软件;②您没有安装办公软件,点此下载办公软件;③swf格式的文件打不开,点此下载qq影音;④PDF格式文档打不开,点此下载PDF阅读器。这些都是常用办公必备软件哦!


注:满足以上情形者均无条件退款!


1、在未拍下前,双方在QQ上所商定的内容,亦可成为纠纷评判依据(商定与描述冲突时,商定为准);

2、在没有"无任何正当退款依据"的前提下,写有"一旦售出,概不支持退款"等类似的声明,视为无效声明;

3、虽然交易产生纠纷的几率很小,但请尽量保留如聊天记录这样的重要信息,以防产生纠纷时便于网站工作人员介入快速处理。
