数形结合是数学中一种重要的思想方法。它将抽象的数学语言与直观的图形结合起来,使复杂问题简单化,抽象问题具体化,化难为易,使问题得到解决。不管是哪门学科知识,都有难易之分,数学知识对于小学生来说,有些知识是比较抽象的,不容易理解、掌握。而数形结合不仅是一种数学思想,更是一种很好的教学方法。在数的认识,概念教学,理解算理,解决问题中,它教会学生分析难点,克服难点,使知识由难变易。从古到今,很多人曾经对数与形的关系作过生动的描绘:
Number combination is an important way of thinking in mathematics. It combines abstract mathematical language with intuitive graphics to make complex problems simple, concrete abstract problems, make life difficult and make the problem solved. No matter what subject knowledge, there are easy points, mathematical knowledge for primary school students, some knowledge is more abstract, not easy to understand and master. The combination of numbers is not only a kind of mathematical thinking, but also a very good teaching method. In the understanding of the number, the concept of teaching, understanding of arithmetic, problem-solving, it taught students to analyze the difficulties and overcome the difficulties, so that knowledge from difficult to change easily. Since ancient times, many people have vividly described the relationship between number and form:
