1 分数乘法分数乘整数教材来源：教育部审定2013 义务教育教科书数学（上册）/人民教育出版社2014年版内容来源：小学六年级数学（上册）第一单元主题：分数乘整数课时：共 13 课时，第 1 课时授课对象：六年级学生设 计 者：张秋白目标确定的依据1.基于课程标准的思考数学课程标准有关本课的要求是:从分数乘整数引入分数乘法教学，帮助学生理解分数乘整数的意义及算理，掌握计算方法。2.教材分析本节课是小学数学人教版六年级上册第一单元“分数乘法”的第一课时，教材第 2 页例题 1 的内容，教材呈现了学生感兴趣的分蛋糕情景，从“每人吃92个蛋糕，3 人一共吃多少个？”的问题入手，得出求3 个相同分数和的算式，然后借助原有乘法知识，转换成分数与整数相乘的算式，再探索分数乘整数的计算方法。目标1.结合生活实例，联系分数加法及分数基本意义，通过对分数连加算式的研究，理解分数乘整数的意义。2.掌握分数乘整数的计算方法，能够应用分数乘整数的计算法则，比较熟练地进行计算。3.通过观察比较，归纳分数乘整数的计算法则，培养抽象概括能力。评价任务1.在小组内互相说一说分数乘整数的计算法则。2.同桌互相背背分数乘整数的计算法则。3.独立完成课堂练习，同桌判断对错。教学过程一、复习旧知（1）列式计算，并说出算式中的两个因数各表示什么？5 个 12是多少？9 个 11是多少？8 个 6 是多少？（2）先口算，再回答问题。40+40+40=15+15+15+15=这两道加法算式中，相同加数各是几？请把它们写成乘法算式好吗?求几个相同加数的和，我们还可以用乘法来计算。评价要点：学生能用加法和乘法两种方法列出算式。二、学习新知例 1 小新、爸爸、妈妈一起吃一个蛋糕，每人 吃92个，3 人一共吃多少个？想：看图，用加法怎样列式？用乘法怎样列式？分别表示什么意思？分数与整数相乘是怎样计算的？小组交流后发表自己的看法，大家评判。加法：92+92+92=乘法：92 3=能先约分的可以先约分，再计算，结果相同。评价要点：学生会根据分数乘整数的计算法则进行计算，特别是能约分的先约分再计算，这个计算过程必须掌握。三、达标测评1.2.83 7 94 5 152 4 125 8
