1、五年级数学学科环保教育教案异分母分数的大小比较教学目标：1、知识目标：结合具体情景，会比较异分母分数的大小，理解通分的意义，能正确地进行通分。2、能力目标：在比较大小的同时体会多种方法解决问题。3、情感目标：渗透环保教育，培养环保意识。教学重点：理解通分的意义教学难点：正确地进行通分教学准备：垃圾处理场地图片教学过程：一、复习同分母分数大小和同分子分数大小的比较方法二、创设情境师：环境污染的问题是当前倍受关注的社会问题，请看大屏幕。（出示情境图）师：观察画面，你发现了什么？你能提出什么数学问题？生：堆放处理的垃圾与填埋处理的垃圾哪类多？师：怎样比较哪类多？生：比较一下和的大小。师：怎样比较这两
2、个分数哪个大？生：可以化成小数比较。生：化成分子相同的分数来比较。生：化成分母相同的分数来比较。师：大家按照自己的想法试试看。（学生独立解决问题，再交流。）师：同学们很会研究问题，你们的策略其实都是将新知识转化成了已有的知识来解决，这是我们研究数学经常用到的方法。我们来看这种方法。（转化成分母相同的分数）师：你是依据什么将这两个分数化成分母相同的分数？生：根据分数的基本性质，分数的分子和分母同时乘一个数，分数的大小不变。将的分子和分母都乘5，的分子和分母都乘7，两个分数的分母都变成了35。师：把异分母分数化成与原来分数相等的同分母分数，叫做通分，通分过程中相同的分母叫做这几个分数的公分母三、自
