方格是数学教学中经常运用的直观图之一,是数形结合的有效载体。在平面图形面积学习中,方格还有其特殊的意义——面积单位。数方格在图形面积教学中是一种直观、简易、原始的计量面积的方法,在各版本小学数学教材中教学平面图形面积时都会用到。但在具体实施过程中,很多时候老师都只是把它单独地作为一种计量面积的方法,对数方格这一环节的教学也只是轻描淡写、一带而过。其实数方格的作用远不止于此,笔者认为它可以统 Checkered is often used in mathematics teaching one of the visual map is an effective vector combination of number. Plane area in the study, the box has its special meaning - area units. Number of squares in the graphic area teaching is an intuitive, simple, original method of measuring area, in the various versions of primary school mathematics textbooks will be used when teaching graphic area. However, during the implementation process, teachers often only regard it as a method of measuring area. The teaching of logarithmic grids is only an understatement. In fact, the role of the grid is much more than this, I think it can be unified
