摘要: “份数法”是小学数学一种重要的解题方法。主要运用在解决小学数学中的倍数、分数乘法、分数除法、按比分配、百分数和解比例等问题中，它犹如一座桥梁，将这些知识紧密地联系在了一起。
Abstract: “Proportion method” is an important method to solve problems in primary school mathematics. This paper analyzes the applications of “proportion method” in solving the problems of multiple, fraction multiplication, fraction division, distribution by ratio, percentage and proportion in primary mathematics. It is like a bridge which closely links the knowledge together and promotes the development of students’ thinking.
