所谓数形结合就是通过数与形之间的相互转化,把抽象的数学语言、数量关系与直观的几何图形、位置关系结合起来,通过“以形助数”或“以数解形”。在小学数学课堂教学中,由于小学生年纪比较小,理解能力比较薄弱,在教学中渗透数形结合的思想,可以使数学算理直观化,帮助学生理解算理、掌握算法;可以使抽象的数学概念具体化,帮助学生形成概念;可以使复杂的数学问题简明化,提高学生解决问题的 The so-called number-shape combination is through the conversion between numbers and shapes, the abstract mathematical language, the number of relations with the intuitive geometry and location of the relationship, through ". In primary school mathematics classroom teaching, because pupils are young and their ability of comprehension is relatively weak, they can penetrate the idea of ​​number and shape in teaching so as to make the mathematics calculation intuitive and help the students to understand the arithmetic and master the algorithm. It can make the abstract mathematics The concept of concrete, to help students form a concept; can make complex mathematical problems simple and improve students to solve the problem
