1、课桌有多长教学设计毛晓雪教学目标：1.再次经历用不同方式测量同一物体长度的过程，体会建立统一度量单位的重要性。2.认识厘米，体会厘米的实际意义。3.初步学会用刻度尺测量物体和线的长度（限整厘米），能估计较小物体的长度。教学重点：认识长度单位“厘米”教学难点：能正确地用直尺测量物体的长度（限整厘米）。教学过程：一、视频导入，激趣揭题师：有三位同学在课前用自己喜欢的方法测量了课桌的长度，我们一起来看看问：为什么同一张桌子，测量出的结果却不一样呢？学生回答。小结：看来测量的标准不同，所得的结果也就不同了。现在我们需要一种标准的、同意的测量工具尺子。二、合作交流，认识厘米1说一说(1)请同桌两人先商量

2、一下用什么工具量，然后量一量你自己的课桌有多长。(2)学生汇报。（学生可能会说：6 枝铅笔长、3 个文具盒长、4 长）(3)讨论：大家的桌子都是一样的，为什么你们说的数却不同？要使量得的结果一样，怎么办？师：看来测量的标准不同，所得的结果也就不同了。统一测量的工具非常重要，那你知道在日常生活中，人们一般用什么工具测量物体的长短呢？我们需要一种标准的、统一的测量工具尺子。2、认识尺子课前小研究（一）：观察尺子，你都看到了什么？介绍刻度、刻度线、厘米。师：厘米是一种常用的长度单位，用它来测量物体的长度，今天我们就一起来认识厘米（板书：认识厘米）三、组织活动，探究新知1、认识 1 厘米。小研究（二）

3、说一说，尺子上从刻度0 到刻度 1 是多长？你还能从尺子上找到这样长的一段吗？你有什么发现？和同桌交流，汇报：尺子上从刻度0 到刻度 1 是 1 厘米。找尺子上其他的1 厘米，谈发现。总结：相邻的两个数字之间的长度就是1 厘米。2、感知 1 厘米。师：找到这么多1 厘米，你能用手比划一下1 厘米吗？（学生试着比划）师：老师课前给大家发给你们那根短短的小棒就是1 厘米，拿出来，用你的大拇指和食指轻轻夹住小棒，然后用另外一只手轻轻地把小棒抽出来，注意两个手指保持不动，看看中间的间隙有多长，这段间隙的长度就是1 厘米，记住1厘米有多长。（学生操作）师：闭上眼睛，想一想1 厘米有多长，想起来了吗？（生

4、比划，师验证，同桌再互相验证。）文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 Z

11、找其他的长度。师：刚刚大家知道从0 刻度到 1 刻度的长度是 1 厘米，那么从0 刻度到刻度 2的长度是多少？（生回答：2 厘米）师：你是怎么知道的？师：你还能在尺子上找到2 厘米吗？说一说你是怎么找的？师：你能找到 3 厘米吗？能快速找到5 厘米吗？师：你们找得这么快的窍门是什么？总结：方法 1：两个数字是几个大格就是几厘米。方法 2：用后面的数减去前面的数，得几就是几厘米。四、自学探究，寻找方法1、师：尺子还有一个作用用来测量物体的长度，怎么测量呢？我们一起来看大屏幕。（播放视频）师：想不想自己动手试着测量一下物体的长度？先估手中小棒的长度？再测量。2、拓展：断尺测量小棒。师：周老师也想测

12、量你手中的小棒。师拿出尺子，故意发出惊叹：糟糕，尺子断了，看来这个尺子是用不成了，扔了吧。生：不用扔，可以用。师：怎么用？（让学生教老师，激发学生探究欲望。）总结：谢谢你们，你们太能干了，竟然变废为宝，只要另选一个起点就可文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5P9T5O10E5 ZX6F1E6X1P3文档编码:CB3P7M9G10Q3 HT5

27、充分发挥他们的学习主体作用，主要体现在以下三个方面：1、注重指导学生操作。让学生在动手操作中，通过自己的努力，主动地获取知识。建立 1 厘米的实际长度的表象是本节课的重点，对二年级学生来说，这一环节的操作指导必须细致、严密、到位才能正确建立起1 厘米的长度观念。我是这样设计的：首先在尺子上找1 厘米，再试着比划一厘米，然后用拇指和食指把 1 厘米的小棒夹住，再把小棒轻轻地抽出来，仔细观察拇指食指之间的缝隙大约是 1 厘米，再举起来自己看一看，闭上眼睛，想一想1 厘米有多长？再次比划，老师验证、同桌验证，调整用手势表示1 厘米。这样指导学生的操作，有条理，动作到位，学生在操作中感知、领悟，顺利建

28、立起1 厘米的长度观念，形成了技能。就是这样在往复用手势比量中来体现学生学习的主体作用。2、放手让学生探索，促进学生主动发展。凡是学生能自己探索出来的决不包办代替，凡是心学生能独立发现的决不暗示。上课伊始，学生通过自己动手、动脑获得桌子的结论，这过程中我绝不作半点代替。在建立了1 厘米的长度观念后接着进入认识几厘米这一环节，我放手让学生尝试在尺子上长出2 厘米、3 厘米长度，并说出道理，这一环节的学习，主要是考虑到学生能独立解决，因此教学时并没有作出任何暗示，而是让学生独立去找，学生在找的过程中发现两个数字之间有几个1 厘米的，长度就是几厘米，这当中学生始终是知识的发现者。文档编码:CB3P7
