探析小学数学中点子图的妙用
龙源期刊网 https://www.360docs.net/doc/3013748614.html, 探析小学数学中点子图的妙用 作者：郑庆锋 来源：《新课程·上旬》2017年第12期 摘要：点子图是小学数学中经常能运用到的一种教学方法，一般是通过点子图的直观载 体帮助学生更好地理解、掌握有关知识点和计算。利用点子图则可以使知识点更加直观化，加深学生的理解，培养学生的逻辑思维能力，促进学生的全面发展。 关键词：小学数学；点子图；思维 教学是师生之间和学生之间交往互动与共同发展的过程。教师是教学过程的组织者和引导者。所以在教学中，教师要能够有创造性地设计教学过程，适当运用“点子图”，使得数学课本中的知识能够灵活、生动、直观地展现在学生面前，让学生能够更好地理解算理，也能够开拓学生的思路，让学生能够运用多元化的思维解决数学问题，有效提高学生理解问题的能力。 一、运用点子图，拓展学生的思维 小学生的思维比较活跃，也比较喜欢联想，但小学数学也是学生系统学习数学的开始阶段，很多课本上的知识，学生理解起来比较困难，所以教师可以运用点子图，拓展学生的思维。 1.帮助学生学会对称图形的画法 对称图像的特点是一般把一个图形沿着一条直线对折，直线两侧的图像能够完全重合，也是把一个图形绕着某一定点旋转一个角度360°/n（n为大于1的正整数）后，与初始的图形重合。小学生只是看着轴对称图形比较好看，但是很少学生会画这些图形，一般学生在作图的时候，会出现移偏、少移的现象。如果运用点子图，则可以帮助学生更好地进行分隔，进一步数清楚点和间隔，让学生更好掌握轴对称图形的特征。一般的题目是让学生在方格中画出要求的图形，那么在实际的教学过程中，教师可以让学生先理解两个点之间的间隔，在这个基础上，让学生找出间隔数相等的关键点，再进行连线。这样的教学过程比较简单，也符合了学生的认知特点。在教师的引导下，学生会慢慢融入课堂中，也可以培养学生学习数学的自信心。 此外，教师也可以运用点子图教给学生画一些基本的平面图形，例如长方形、正方形和三角形等，这些看似比较简单的点子图，可以帮助学生开拓思路，让学生有新的收获。 2.帮助学生构建问题解决的模型 在小学数学中要解决问题的很多，有的可以用加减法解决问题，有的是乘除法解决问题，还有的是运用四则运算解决问题，那么在这些计算中，可以运用点子图构建合理的模型，帮助学生建立起运算的“桥”，简化学生的运算。
