精品教学教案8、9 的分与合教学设计重庆市万州区电报路小学张英华教学内容人教版数学一年级上册第五章第52 页。教学目标1.掌握 8、9 的分解与组成，领悟规律，加深对10 以内数的认识。2.经历动手实践、自主探索、合作交流的学习过程，发展初步的动手实践的能力、语言表达能力及合作交流的意识。3.领会分与合的思想，并体会数学知识是相互联系的。教学重点通过实践，探索得出8、9 的分与合，并领悟规律。教学难点掌握并领悟 8、9 的分与合的规律。教学用具多媒体课件、学具盒。教学过程一、复习导入1.口算（开火车）5+2 4+1 6-2 3+4 6-6 5-2 7-5 6+1 5+0 4-0 5-2 5+1 7-6 6-4 2你看到了什么？这些是我们的生肖呀。图中有几个生肖？把左边的 8 只小动物圈起来，给从左数第8 只小动物画上出示生肖图3.把下面各数按从大到小的顺序排一排：精品教学教案听说今天要到这里来上课，有几个数字宝宝也跟过来了，他们不守纪律啦，排得乱七八糟的。你能帮它们排排对队吗？6 3 8 7 0 9 2 5 刚才有 2 个小朋友坐得得特别好，老师带了一些小星星准备奖给他们。猜一猜，我会 怎样分配这些小星星呢？有多少种分发？怎样分最好？你们来帮老师分一分好不好？三、探索新知1.谈话：小朋友数一数，老师这儿有几个小星星？（课件展示）我先移动一个，请你说说它分成了几和几，几和几合成8？如果我再移动一个，想一想，8 又分成了几和几，几和几合成8？就这样，每次移动一个小星星，移一次，说两句话，你会吗？请把你的 8 个小星星横着摆成一排，自己练习一遍，然后再移给同桌看，说给同桌听。再将每次移动后得到的8 的分与合按顺序填在第35 页上面的方框里。好，开始。学生操作、表述，教师巡视、指导。集体交流：你是怎么填的？指名回答。第一次向右移动一个，怎么填的？再移动一个呢？下面呢？根据学生回答板书8 的四个分合式。你填对了吗？同桌互相检查，如果有错，马上改正。3、看了 8 的这几个分的式子，你还能想到什么？板书 8 的 3 个分合式。文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1

和 2。3.9 的分与合（1）情境引入。妈妈买了 9 枝花，请小明插在2 个花瓶里，可以有几种插法？（2）探究学习。你可以一边摆花的学具图片，一边把分法记录下来，也可以在纸上直接写出你是怎么分的。一边做，一边说。（3）汇报结果。1）全面展示：老师板书。2）探究规律：还有别的分法吗？你有什么想问的吗？这样写有什么好处？看一个就能记住另外一个，因此 9 的分与合就只需要记住4 个，这样简便了很多。（4）学生观察，巩固新知。老师板书 9 的组成，简写。文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4 ZE9W6X4L5Q6文档编码:CM4K7U10C5W1 HL3Y2R10S7T4
