数量关系是小学数学中捋顺解题思路的关键。许多小学生不会解决应用题,实际上就是没有掌握如何在情境描述中厘定数量关系,只有引导他们掌握捋顺已知量与未知量数量关系的技巧,才能让他们真正掌握解决应用题的方法。
The quantitative relationship is the key to solving the problem in the elementary mathematics.

Only by guiding them to master the relationship between the known quantity and the unknown quantity can they really master the solution to the problem.
