上三年级的女儿拿来一道数学题跟我讨论,题目如下:求A、B、C各表示多少。女儿跟我说,她找到了一种很简单的方法,只要用888除以3就可以了。但她说自己还没有学过如何计算888除以3(她上三年级,当时还只学了用竖式计算表内除法和相应的“有余数除法”)。以下是我和女儿的一段对话:笔者:你没学过如何计算888除以3,但你应该知道这道除法题表示什么意思吧?女儿:知道,就是把888平均分成3份。笔者:知道这个就好办了!你想办法去分就是啦。比
The third grade daughter took a math problem to discuss with me, the title is as follows: Seeking A, B, C each said how much. Daughter told me that she found a very simple way, as long as 888 divided by 3 on it. But she said she had not learned how to count 888 divided by 3 (she was in the third grade when she had only learned to use the divisor and the corresponding “divisor”). The following is a dialogue between my daughter and I: I have not learned how to calculate 888 divided by 3, but you should know what is the meaning of this division? Daughter: You know, divide the 888 equally into 3 parts. I know this is easier to handle! ratio
