数形结合思想,就是根据数与形之间的对应关系,把抽象的数与直观的形联系起来,通过相互转化来解决数学问题的思想。在小学数学教学中,主要表现为把抽象的数量关系与形象的几何图形相结合,运用图形直观的特征去发现数量之间的内在联 The idea of ​​combining figures with numbers refers to the idea of ​​solving mathematical problems through mutual transformation according to the correspondence between numbers and shapes, linking abstract numbers with intuitive shapes. In primary school mathematics teaching, the main performance is the number of abstract relations with the geometric image of the combination of the use of graphical intuitive features to find the number of internal link
