希尔伯特说过:“问题是数学的心脏,方法是数学的行为,思想是数学的灵魂。”由此可见数学思想方法的重要性。数形结合就是按照数量与图形之间的对应关系,借助数与形的相互转化来解决数学问题的一种重要的数学思想方法。在教学中有机地将“数”的严谨性和“形”的直观性相结合,可使抽象的概念直观化,枯燥的算式形象化,让学生在理解算理的基础上掌握算法,从而拓展学生解决问题的思路,培养学生灵活运用知识的能力,提高数学素养。
Hilbert said: “The problem is the heart of mathematics, the method is the behavior of mathematics, the thought is the soul of mathematics ” This shows the importance of mathematical thinking method. The combination of numbers is an important mathematical method to solve mathematical problems by means of mutual transformation between numbers and forms according to the correspondence between quantity and figure. The combination of rigor of “number ” and “form ” intuitively in teaching can visualize the concept of abstraction and make the boring formula visualized so that students can grasp the basis of understanding arithmetic Algorithm, thus expanding the students to solve the problem of thinking, cultivate students the ability to use knowledge flexibly, improve math quality.
