22、就是分析数量之间的关系，进行推理，由已知求得未知的过程。学生解答应用题时，只有对题目中的数量之间的关系一清二楚，才有可能把题目正确地解答出来。换一个角度来说，如果学生对题目中的某一种数量关系不够清楚，那么也不可能把题目正确地解答出来。因此，牢固地掌握基本的数量关系是解答应用题的基础。什么是基本的数量关系呢？根据加法、减法、乘法、除法的意义决定了加、减、乘、除法的应用范围，应用范围里涉及到的内容living standards, poor farmers in less than complete elimination of 4600 Yuan, 8949, 19008. “Five wate

Agriculture and tourism, education, culture, health, pension and other deep integration, develop leisure, travel就是基本的数量关系。例如：加法的应用范围是：求两个数的和用加法计算；求比一个数多几的数用加法计算

43、。这两个问题就是加法中的基本数量关系。怎样使学生掌握好基本的数量关系呢？首先要加强概念、性质、法则、公式等基础知识的教学。举例来说，如果学生对乘法的意义不够理解，那么在掌握“单价数量=总价”这个数量关系式时就有困难。其次，基本的数量关系往往是通过一步应用题的教学来完成的。人们常说，一步应用题是基础，道理也就在于此。研究怎样使学生掌握好基本的数量关系，就要注重对一步应用题教学的研究。学生学习一步应用题是在低、中年级，这时学生年龄小，他们容易接受直观的东西，而不容易接受抽象的东西。所以在教学中，教师要充分运用直观教学，通过学生动手、动口、动脑，在获得大量感性知识的基础上，再通过抽象、概括上升到理性

44、认识。下面以建立有关倍的数量关系为例来说明。两个数量相比，既可以比较数量的多少，也可以比较数量间的倍数关系。这就是说，“倍”也是在比较中产生的。在教有关“倍”的数量关系时，核心问题是对“倍”的认识。为了使学生理解“倍”的意义，教学中可以这样进行：living standards, poor farmers in less than complete elimination of 4600 Yuan, 8949, 19008. “Five waters rule“: the County invested 2.169 billion yuan, similar counties line the
