小数和复名数的教学是在前面的名数改写的基础上进一步的深入，名数的改写一方面使学生进一步记熟单位间的进率，另一方面也教学给学生进行名数间改写的般方法。名数的改写对于学生的来讲是一个难点，因为名数的改写正确的.前提是学生对各单位进率熟悉，如何让学生熟记各单位进率呢？我的做法是帮助先归纳整理各单位进率，让学生把各单位及进率抄在自己的课本上，让学生利用早读时间和课前几分钟读单位进率及默写单位进率，让学生深记忆。
在小数和复名数的教学中，我先让学生先整理各单位及进率，让学生在学习前有一个知识回顾的过程，然后引导学生在做小数和复名数改写时如：3.4平方千米＝（）平方千米（）米，先根据题目的要求，如看清楚是什么名数改写成什么名数、是大单位转换成小单位或小单位转换成大单位，然后，再把小数分开两部分处理：整数部分照写，小数部再根据各单位及其进率进行量的转化、把小数点移动，实现小数和复名数之间的改写。这样给学生一个清淅的解题思路，学生解题的正确率自然得到保证。
总之，在做小数和复名数的转换教学中必须要让学生熟记各单位及进率，基础打好了，做事自然事半功倍。

There was a farmer in the Song Kingdom in ancient China. He worked in his field day after day. In good harvest years, he could only have enough food to eat and enough clothing to wear. If the field failed to produce enough crops, he had to go hungry. This farmer wanted to improve his life. But he was too lazy and too cowardly. He always dreamed of having unexpected fortune.
A miracle took place at last. One day, when he worked in the field, some people were hunting nearby. They shouted loudly one after another. Some little animals were running desperately. Suddenly, a hare dashed itself headlong against the stump of a dead tree in his field and died.
That day, he had a good meal.
From that day on, he no longer worked in his field. From morning till night, he stayed by that miraculous stump, waiting for another hare. Will the miracle happen again?
People often use the set phrase “staying by a stump waiting for more hares to come and dash themselves against it" to refer to persons dreaming to reap without sowing.

奇迹终于发生了。一天，他正在田里干活，一群打猎的人靠近了。吆喝之声四处起伏，受惊的小动物们没命地奔跑。突然， 有一只兔子，不偏不倚，一头撞在他田边的树根上。
这天，他美美地饱餐了一顿。
从此，他就不再种地了，一天到晚守着那个神奇的.树根，等着奇迹再次出现。
