17、乘整数的计算方法。（1）提问：3 个92相加的和，也可以列成算式923，那么923 又应该怎样计算呢？（2）学生思考计算方法。学生思考，教师巡视观察。如果学生有困难，可以进行必要的启发：92是 2 个91，2 个91乘 3 就是 6 个91，所以就是96。（3）组织全班交流，教师结合学生的回报情况进行板书：923=92+92+92=9222=932=96=32（个）教师强调：在计算过程中，虚线框起来的思考过程可以不写；分数线要用直尺画。（4）学习计算过程中进行约分。引导学生观察计算过程中的分子和分母，分子用“23”得来，说明分子中含有因数3，而分母是“9”，也含有因数3，所以将“3”和“9”进

18、行约分，即：923=39321=32（个）观察上面的计算过程，你发现了什么？（预设：能约分的可以先约分，再计算，结果相同。）（5）提问：如果把算式“923”的两个因数交换位置，变成“392”，又应该怎样计算呢？学生尝试计算后组织交流。（6）总结分数乘整数的计算方法。第 4 页，共 5 页文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6

26、，从而体会到分数乘整数的意义和整数乘法的意义相同。3.教材第 6 页“练习一”第2 题。这道题是分数乘整数知识在日常生活中的应用，5kg 的衣物就需要 5 个21勺洗衣粉。四、反思总结通过本课的学习，你有什么收获和体会？还有哪些疑问？第 5 页，共 5 页文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9O3K8M4O6 HM10K5Z2M2S2 ZF6I4E1I5F7文档编码:CR9
