论文部分内容阅读
这是老师们经常讨论的问题。讨论过程中形成的一些观点还很有意思。比如:观点一:没有把0划归为自然数时,我们都说最小的一位数是1,现在0被规定为自然数了,最小的一位数就应该是0。观点二:0肯定不是一位数,如果0是一位数,那00不就是两位数了?老实说,学生讨论这个问题,对提高其数学素养没有太多帮助。教师讨论这个问题,对提高教学水平也没有太多帮助,但却有利于我们进一步认识数学及其讨论问题的方式。于是我参与了一个讨论。以下是这段讨论的内容——教师A:请问:最小的一位数是1还是0?众老
This is a question teachers often discussed. Some of the points discussed during the formation of the very interesting. For example: Point 1: 0 is not classified as a natural number, we say that the smallest digit is 1, and now 0 is defined as a natural number, the smallest one-digit should be 0. Opinion two: 0 is certainly not a single digit, if 0 is a single digit, that 00 is not double digits? To be honest, students discuss this issue, to improve their mathematical literacy is not much help. Teachers discussing this issue is not much help to improve the teaching level, but it helps us to further understand mathematics and the way it discusses the issue. So I participated in a discussion. The following is the content of this discussion - Teacher A: Excuse me: Is the smallest single digit is 1 or 0?
