数形结合是中学数学四种重要基本思想方法之一,是数学的本质特征。在解决数学问题时,将抽象的数学语言同直观的图形相结合,实现抽象的概念与具体形象的联系和转化,使数与形的信息相互渗透,可以开拓解题思路,使许多数学问题简单化。结合初中数学课堂教学实践,就数形结合教学进行简单探究。
The combination of number and shape is one of the four basic methods of thinking in middle school mathematics, and it is an essential feature of mathematics. When solving mathematics problems, the abstract mathematics language is combined with the intuitive graphics to realize the connection and transformation of abstract concepts and concrete images, so that the information of numbers and shapes can infiltrate each other, and the problem-solving ideas can be developed, simplifying many mathematical problems. Change. Combining the practice of mathematics classroom teaching in junior high schools, a simple inquiry into the combination of number and shape teaching is carried out.
