分数除法是五年制小学数学第九册(六年制第十一册)教材中的一个重要内容。通过本单元的教学,使学生在分数乘法的基础上进一步理解和掌握分数除法的意义和计算法则,正确、熟练地进行分数乘除的计算;并能解答简单的分数除法应用题,为后面学习分数四则混合运算和应用题打下基础。 分数除法的意义与整数除法的意义完全相同,都是已知两个因数的积和其中的一个因数,求另一个因数的运算。不同的是分数除法的教学重点是理解和掌握分数除法的法则。为了便于学生逐步理解,教学分数除法时,一般先让学生学分数除以整
The fractional division is an important part of the textbook of the ninth grade of five-year elementary mathematics (six-year eleventh volume). Through the teaching of this unit, students can further understand and master the meaning and calculation rules of fractional division on the basis of fractional multiplication, correctly and skillfully calculate the fractional multiplication and division, and can answer the simple question of fractional division, Four mixed computing and application questions lay the foundation. The meaning of fractional division and integer division exactly the same meaning, are known two products of the product factor and one of them, seeking another factor operation. The difference is that the teaching of fractional division focuses on understanding and mastering the rules of fractional division. In order to facilitate students to gradually understand, teaching division, the general first let students divided by the whole number of points
