一、数形结合与数学教学数形结合是根据数量与图形关系来解决问题的一种数学思想方法。几何图形可以用数量关系来公式化,反之,数量关系可以用几何图形来表现。两个领域中的概念和关系得到更明晰的阐述——几何概念变得更加抽象而易于处理;数量关系则变得更加形象而易于直观理解
First, the combination of mathematics and mathematics teaching is a mathematical thinking method to solve problems based on the relationship between quantity and graph. Geometry can be formulated with a quantitative relationship, whereas a quantitative relationship can be represented with a geometric shape. The concepts and relationships in the two fields are more clearly articulated - the concept of geometry becomes more abstract and easy to handle; the quantitative relationship becomes more visual and easy to understand intuitively
