数形结合思想是通过数和形之间的对应关系和相互转化来解决问题,把数或数量关系与图形对应起来。小学低年级教材中蕴含着丰富的数形结合素材,正确运用数形结合思想,有利于学生更加形象直观地了解数的概念、数与数之间的关系以及潜在的数学规律。那么,教师在低年级的数学教学过程中,如何抓住数与形的特征,在探究中渗透数形结合思想,让学生初步感知、领悟?对此,笔者作了一些相关尝试。一、借“形”的直观性形象地理解“数”
The idea of number combination is to solve the problem through the correspondence between number and shape and mutual transformation, and the number or quantity relationship is corresponding with the figure. The low grade primary school textbooks contain a wealth of combination of shape and material, the correct use of shape combination of ideas is conducive to students a more intuitive understanding of the concept of number, the relationship between the number and the potential mathematical rules. Then, in the process of mathematics teaching in the lower grades, how can teachers grasp the characteristics of numbers and shapes, penetrate numbers and form ideas in combination with the thoughts so that students can initially perceive and comprehend? In this regard, the author made some attempts. First, by the “shape ” intuitive image to understand “number ”
