读了贵刊1993年第8期的《关于“1÷7”的阅读与思考》一文,受益匪浅,但又感到言犹未尽。正如文中所说,要真正弄懂分数化小数这个问题,必须弄通人教版中师数学课本《小学数学基础理论和教法》第一册 P_(200)“化分数为小数”(或人教版小学教师培训教材《算术》P_(176)“小数与分数”)这一单元。但这对许多小学教师来说,一时难以做到。这里试图用一简单方法说明“1÷7”这种类型的除法,所得
Read your magazine No. 8 of 1993 “on the” ÷ 7 “reading and thinking,” a text, benefit a lot, but I still feel uncompleted. As mentioned in the article, in order to really understand the problem of fractional decimals, we must work through the mathematics textbook of the PEP to solve the problem of “fractional fractional numbers” (or people Teaching primary school teacher training materials “arithmetic” P_ (176) “decimals and scores”) this unit. But for many primary school teachers, it is hard to do so. Here try to use a simple way to explain the “1 ÷ 7” this type of division, the income
