笔算两位数加减两位数不进位不退位

第11 课时两位数加、减两位数(不进位、不退位) 4 月29 日) 教学目标: 1.让学生经历探索两位数加、减两位数(不进位、不退位)笔算方法的过 程,能用竖式正确地进行计算。 2.让学生在解决简单的实际问题的过程中,进一步体验数学与生活的联系,增强数学意识,培养思维能力和合作学习的态度。 教学内容:教科书第57——58 页 教学重点、难点: 让学生掌握两位数加、减两位数笔算的基本方法。 教学准备: 挂图 教学过程: .复习 1.口算:20+40 * 20+16 85-70 39-3 40+5 * 2+76 打“*”题让学生说说是怎样算的。 2.填空; (1) 5 个十是()。 2)31 里面有()个十和()个一。 3) 4个十和5 个一合起来是()。 4) 78 的()在十位上,表示7 个();个位上是(),表示8 个()。 二、自主探究,体会领悟 1.教学例题 师:今天有一些小朋友们要去参观动物园,想请大家帮他们解决坐公交车时遇到的数学问题。 出示情境图 让学生仔细观察挂图,读图中人物的对话。 问:从图上你了解到哪些信息?要解决什么问题?

师:从图上我们可以看到蓝色公共汽车上坐了45 人,红色公共汽车上坐了

31 人,要求两辆车一共坐了多少人。算式怎么列?可以列算式43+31 板书:45+31= 问:45+31怎样算呢?可以用手边的小棒摆一摆,也可以用计数器拨一拨, 还可以用你自己的方法算一算。想好后在四个人小组里交流一下你的方法。 师:你们想到了哪些办法?哦,有小朋友是摆小棒的。先摆43 根小棒,再 摆31 根小棒;把3 根小棒和1 根小棒合起来是4 根小棒,把40 根小棒和30 根小棒合起来是70 根小棒;最后把70 根小棒和4 根小棒合起来共是74 根小 棒。 师:还有小朋友是拨计数器帮助的。先在十位上拨4 粒珠子,在个位上拨3 粒珠子,表示43;接着在十位上加3 粒珠子,也就是加30,现在计数器 上表示73;最后在个位上加1 粒珠子,表示加1,最后计数器上表示的 数是74。 师:除了刚才小朋友们讲到的方法,这道题还可以怎样算呢? 我们还可以用竖式计算。学生独立思考后在小组里交流,最后推选代表汇报 结果。板书:40+30=70 3+1=4 70+4=74 谈话:请同学们回想一下,刚才你们用小棒计算时,把4捆和3 捆合在一起,把3根和1根合在一起;用计数器计算时,40和30都拨在十位上,3和1都拨 在个位上。有的同学心中想的算法是先算40+30,再算3+1。想想,这些算法的 相同点是什么? 讲述:在计算加法时,必须个位上的数与个位上的数相加,十位上的数与十位上的数相加。这样的算式,除了用同学们刚才提到的几种方法计算以外, 还可 以用竖式计算: 边板书边说明:先写第一个加数43,4”在十位上表示4 个十,“3”在个 位上表示3 个一(用红笔写出“十个”);再写加31,加号写在31 的 前面,“3”要和十位上的4 对齐,1”要和个位上的3 对齐;然后用直 尺画上横线,表示等号。计算的时候可以先算个位上的3加1,得4,这 个“4”表示4个一,写在个位上;再算十位上的4加3,得7,这个“7”
