除数是小数的除法是苏教版五年级上册教材“小数乘法和除法”单元的教学难点之一。因为学生在面对“一个数除以小数”这样一个新的计算问题时,首先要能想到将它进行转化,接着还要考虑将它转化成怎样的式题,以及怎样转化、依据什么进行转化,等等。同时,由于上述思考过程相对比较复杂,学生完成相关计算时难免会出现各种失误,所以教学时需要教师适当加以引领,以便于学生通过合乎
Divisor division is the decimal division of the Soviet version of the fifth grade textbook “decimal multiplication and division ” unit teaching difficult. Because students face a new computational problem such as “dividing a number by a decimal number”, one must first think about transforming it, and then consider what kind of style it is transformed into and how to transform it according to what Conversion, and more. At the same time, due to the relatively complicated process of thinking mentioned above, students will inevitably experience various mistakes when completing relevant calculations. Therefore, teachers should be properly guided in teaching in order to facilitate students’
