课堂教学效果反馈小卷
第一单元 小数乘法
第1节 小数乘整数（例1）
基础过关
1.仔细想，认真填。
⑴把2.5的小数点向左移动一位是（ ），（ ）扩大到原来的10倍是84.6。
⑵在计算0.37×12时，把0.37看作整数（ ），它就扩大到原来的（ ）倍，运算结果必须缩小到原来的（ ），才能得到0.37×12的积。
⑶0.785×17的积有（ ）位小数。3.8×29的积有（ ）位小数。
2.用竖式计算。
4.38×21 25.4×32 4.08×9
能力提高
在迎接新同学的联欢会准备工作中，五（1）班买了一条彩带。同学们第一次用去彩带的一半，第二次又用去剩下的一半，第三次又用去剩下的一半后还剩下6.38m,这条彩带原来长多少米？
