数形结合思想在小学数学教学中应用有其必要性。一是将复杂的问题简单化。如若能在当前小学数学教学过程中实现对数形结合的应用,教学势必会事半功倍。例如应用题中,电影院、家、学校三处同在马路一边,家与学校之间距离200米,电影院与学校之间距离300米,问家与电影院之间距离多少米?这样的问题在解答过程中使用数形结合的方法就会使问题迎刃而解。二是将抽象问题形象化。数学作为一门抽象学科,小学阶段的学生是比较难理解的,这就须
The combination of the idea of number and shape in elementary mathematics teaching has its necessity. The first is to simplify complex issues. If we can realize the application of the logarithmic combination in the current elementary mathematics teaching process, the teaching is bound to do more with less. For example, the application title, cinema, home, school three at the same side of the road, home and school 200 meters away from the distance between the cinema and school 300 meters, asked the distance between the home and the cinema how? The process of using a few forms of combination will solve the problem. The second is to visualize the abstract problem. Mathematics as an abstract discipline, primary school students are more difficult to understand, which must be
