2022年人教版六年级数学上分数除法应用题教案例题及练习题 .pdf

精品教学教案课题已知一个数的几分之几是多少求这个数的应用题年级学习目标与考点分析掌握“已知一个数的几分之几是多少，求这个数”的应用题的解答方法，熟练的列方程学习重点弄清单位“1”的量，会分析题中的数量关系。学习方法讲练结合学习内容与过程一知识点回顾1.分数除法的意义2.分数除法的计算法则二重点、难点、易错点重点：弄清单位“1”的量，会分析题中的数量关系。难点：分数除法应用题的特点及解题思路和解题方法。易错点：容易与分数除法应用题混淆三讲授新课（1）已知一个数的几分之几是多少求这个数的应用题一、复习1、出示复习题：根据测定，成人体内的水分约占体重的32，而儿童体内的水分约占体重的54，六年级学生小明的体重为35千克，他体内的水分有多少千克？2、让学生观察题目，看看题目中所给的三个条件是否都用得上，并说说为什么。3、选择解决问题所需的条件，确定出单位“1”，并引导学生说出数量关系式。小明的体重54体内水分的重量4、指名口头列式计算。二、新授1、教学例1 的第一个问题：小明的体重是多少千克？（1）读题、理解题意，并画出线段图来表示题意：精品教学教案（2）引导学生结合线段图理解题意，分析题中的数量关系式，并写出等量关系式。小明的体重54体内水分的重量（3）这道题与复习题相比有什么相同点和不同点？（相同点是它们的数量关系是一样的；不同点是已知条件和问题变了）（4）这道题什么是单位“1”？单位“1”是已知的还是未知的？怎样求？（引导学生根据数量关系式，将未知的单位“1”设为，列方程来解决问题）（5）启发学生应用算术解来解答应用题。（根据数量关系式：小明的体重54体内水分的重量，反过来，体内水分的重量54小明的体重）2、解决第二个问题：小明的体重是爸爸的157，爸爸的体重是多少千克？（1）启发学生找到分率句，确定单位“1”。（2）让学生选择一种自己喜爱的解法进行计算，独立解决第二个问题。（3）指名说说自己是怎样理解题意的，解题思路。（出示线段图）爸爸：小明：爸爸的体重157小明的体重方程解：解：设爸爸的体重是千克。算术解：3515775（千克）15735

题。（先分析数量关系式，然后确定单位“1”，最后再进行解答。第二题注意引导学生发现250ml 的鲜牛奶是多余条件）2、练习十第6 题（引导学生先求出单位“1”爸爸妈妈两人的工资和15001000，再根据数量关系式进行计算）四、总结这节课我们学习了分数应用题中“已知一个数的几分之几是多少求这个数的应用题”，我们知道了，如果分率句中的单位“1”是未知的话，可以用方程或除法进行解答。（2）稍复杂的分数除法应用题一、复习小红家买来一袋大米，重40 千克，吃了85，还剩多少千克？1、让学生画出线段图。2、学生独立解答。3、集体订正。提问学生说一说两种方法解题的过程。4、小结：解答分数应用题的关键是找准单位“1”，如果单位“1”的具体数量是已知的，要求单位“1”的几分之几是多少，就可以根据分数乘法的意义，直接用乘法计算。二、新授1、教学补充例题：小红家买来一袋大米，吃了85，还剩 15 千克。买来大米多少千克？（1）吃了85是什么意思？应该把哪个数量看作单位“1”？（2）引导学生理解题意，画出线段图。（3）引导学生根据线段图，分析数量关系式：买来大米的重量吃了的重量=剩下的重量（4）指名列出方程。解：设买来大米X 千克。x85x=15 2、教学例2（1）出示例题，理解题意。吃了85剩下 15 千克？千克“1”文档编码:CZ8B5A7I7T5 HI8M8Y5O9O6
