应用题教学在整个小学数学教学中占有重要地位。为了提高学生解题能力,教师应该重视数量关系的分析,尤其要熟悉小学应用题中常见的基本数量关系。小学应用题有四种基本数量关系:部分数与总数的关系;两数相差关系;每份数、份数与总数的关系;大数、小数与倍数的关系。现分述如下:
Applied problem teaching plays an important role in the entire primary school mathematics teaching. In order to improve students' ability to solve problems, teachers should pay more attention to the analysis of quantitative relationships, especially familiar with the basic quantitative relationships commonly found in elementary applied questions. Primary school questions have four basic quantitative relationship: the relationship between the number of parts and the total number; the difference between the two numbers; the relationship between the number of copies, the number of copies and the total number; the relationship between large numbers, decimals and multiples. Now as follows:
