分数除以整数(0除外)等于分数乘以整数的倒数。这是我们曾学过的分数除以整数的计算法则。然而在今天“自主、合作、探究”的课堂上,它却受到了质疑和挑战。[教学片段]师:小组交流,谁能归纳分数除以整数的计算方法?生1:分数除以整数,等于分数乘以这个整数的倒数。师:同意吗?生2:我不同意。分数除以整数,整数不能为零,应
Dividing a fraction by an integer (except 0) equals the fraction multiplied by the reciprocal of the integer. This is a calculation rule that we have learned of dividing fractions by integers. However, in today’s “autonomous, cooperative and exploratory” classroom, it has been questioned and challenged. [Teaching fragment] division: group exchange, who can be divided by the integer method of calculating the score? Health 1: divided by an integer, equal to the fraction multiplied by the reciprocal of this integer. Teacher: Agree? Health 2: I do not agree. Divide the score by an integer, the integer can not be zero, should be
