6 用小数除法解决实际问题本节课的内容是教材第39页例10。

例10是根据实际需要用“进一法”和“去尾法”取商的近似值。

体会根据实际情况用“进一法”和“去尾法”取近似数的必要性。

由于这两道题算出的结果都是小数,而需要准备的瓶子和包装的礼品盒都必须是整数,因此都要取这些结果的近似数。

取近似值时,不能机械地使用“四舍五入”法,要根据具体情况确定是“舍”还是“入”。

1.结合生活中的实际情况能用“进一法”和“去尾法”求商的近似数。

2.在分析问题、解决问题的过程中,正确理清问题中的数量关系。

3.经历解决实际问题的过程,体验分析、综合的学习方法和解决问题的策略。

4.感受数学知识与实际生活的密切联系,培养应用数学的意识,体验解决实际问题的乐趣。

【重点】能结合实际情况用“进一法”和“去尾法”求商的近似数。

【难点】正确理清问题中的数量关系。

【教师准备】PPT课件,口算题卡若干张。

1.老师谈话:数学来源于生活,也要应用于生活。

在生活中,我们经常要运用所学的数学知识来解决问题,这一单元我们主要学习的是小数除法。

看看这些知识可以帮助我们解决哪些实际问题。

2.PPT课件出示教材第39页例10(1)的情境图。

小强的妈妈要将2.5 kg香油分装在一些玻璃瓶里,需要准备几个瓶子?3.学生读题,找出题中的已知条件和要解决的问题,分析数量之间的关系。

4.指名回答。

预设生1:已知条件是:要把2.5 kg香油装进瓶子里,每个瓶子最多可以装0.4 kg。

生2:问题是“需要准备几个瓶子?”师:怎样解决这个问题呢?预设生:用香油的总质量除以每个瓶子装香油的质量等于需要瓶子的个数,列式为:2.5÷0.4。

把数学知识与生活实际相联系:一是能吸引学生的注意力;二是能体现生活与数学的紧密关系,更能激发学生的求知欲。

1.口算(用口算卡片出示题目)。

4.5÷9= 3.6÷4=4.2÷0.6= 1.5÷0.3=2.笔算。

人教版数学五年级上册《解决问题》人教版数学五年级上册《解决问题（进一法和去尾法）》教材简析“解决问题———根据实际取商的近似值”是人教版数学五年级上册第三单元小数除法例10的教学内容。

例题由玻璃瓶分装香油和红丝带包装礼盒两个问题组成，呈现“阅读与理解”“分析与解答”“回顾与反思”的结构思路，让学生经历“整理信息——分析关系——列式计算——检验反思”的全过程。

由于两道题算出的结果都是小数，而需要准备的瓶子和包装的礼盒都必须是整数，因此都要取商的近似值。

这样，“进一法”和“去尾法”的学习就渗透在解决分装香油和包装礼盒的问题中。

在取近似值时，不能机械地使用“四舍五入法”，而是要根据具体情况确定是“舍”还是“入”。

教材强调“在解决实际问题时，要根据实际情况取商的近似值”。

学情分析五年级的学生经过四年的学习，已具有一定的观察分析、归纳总结、表达交流等这些能力，能从已有的知识和经验出发获取知识，抽象思维有了一定的发展。

在学习本课之前，学生已掌握了小数除以整数，小数除以小数和用“四舍五入”法求近似值的相关知识。

在此基础上学生再来学习本节课的内容，计算方面不会感到太困难。

重点是引导学生能根据实际情况进行正确地分析，选择正确的方法取商的近似值。

本节课注重培养学生根据实际情况灵活处理“商”，感受数学与生活的紧密联系。

教学目标1.通过对不同生活情境的分析与思考，体会近似值的生活意义。

2.在实际应用中，会灵活选择用“去尾法”和“进一法”取商的近似值，培养解决问题的能力。

3.经历和探寻解决实际问题的过程，培养分析、比较、灵活解决问题的能力，并学会与他人合作交流。

4.通过例题和习题的学习，感受数学与生活的紧密联系，体会数学的价值。

教学重难点教学重点：：体会用“进一法”和“去尾法”求商的合理性，并会根据实际情况运用“进一法”和“去尾法”求取商的近似值。

教学难点：能根据实际情况运用“进一法”和“去尾法”求取商的近似值。
