《小学教学研究》一九八二年第六期上刊载了“6407000应该怎样读?”一文,文章中涉及了多位数、小数、名数的读法等方面的问题,下面谈谈个人的几点不成熟的看法: 1、什么是“6407000”的规范读法? 统编小学数学教材规定了读数的法则:“读数的时候,从高位到低位,一级一级地往下读。读亿级、万级时,按照个级的读法去读,只要在后面加上‘亿’字或‘万’字就可以了,一个数中间有一个0或者连续几个0,都只读一个零,末尾所有的0都不读出来。”根据这一规定,小学数学教学中“6407000”的规范读法应该是“六百四十万零七千”而不应该是“六百四十万七千”。 2、能够把“6407000”读作“六百四十万七千吗”? 多位数的读法,各国有各自的习惯和规定,比如日本的读数法就不涉及0的读法问题,把“19100047”
“Primary School Teaching Research,” published in the sixth issue in 1982, “6407000 should be read?” Article, the article covers multi-digit, decimal, name of the reading method and other issues, the following talk about the individual What are the “6407000” normative reading? The compilation of primary school mathematics textbooks provides the reading of the law: “Reading time, from high to low, read down one level down. Billion, 10,000, according to the level of reading to read, as long as the back of the 'million' or 'million' word on it, a number of intermediate 0 or a few consecutive 0, read only one Zero, at the end of all 0 are not read out. ”According to this regulation, primary school mathematics teaching“ 6407000 ”normative reading law should be“ 6,470,700 ”and should not be“ 6.4 million Seven thousand. ” 2, Can “6407000” be read as “6,447,000?” Multi-digit reading, each country has its own customs and regulations, such as Japan's reading method does not involve 0 reading law, the “19100047”
