【错误现象列举】小数除法是五年级上册小数计算教学中的一个重点内容,而这部分的计算是学生错误比较集中的地方,通过总结发现学生在计算小数除法时错误较多的题,主要是商中丢“0”这种情况。具体学生常见错误有以下五种。错误1:被除数整数部分小于除数,不够除,就商0。如:4.62÷22,有的学生用整数除法的方法计算,先看被除数第一位,不够除,就看前两位,于是就用46除以22,商就成了21。错误2:被除数的位数小于除数,不够除时,商0,再 [Wrong phenomenon enumeration] Fractional division is a key content in the fifth grade uppercase fractional calculation teaching, and this part of the calculation is the place where students’ mistakes are concentrated. Through summarizing, students find many mistakes when calculating decimal division, mainly Business lost “0 ” this situation. Specific students have the following five common mistakes. Error 1: the integer part of the dividend is less than the divisor, not enough, on the business 0. Such as: 4.62 ÷ 22, some students use the integer division method to calculate, first look at the first divisor is not enough, in addition to the first two, so use 46 divided by 22, the business becomes 21. Error 2: The number of dividends less than the divisor, not enough time, quotient 0, and then
