方格图在小学数学教学中的有效应用

The Effective Application of Square Diagram in Primary Mathematics Teaching

方格图作为直观形态的数学学习工具,将学科的理趣和学习的情趣相结合,具有帮助学生提高数学学习能力的作用。本文以人教版小学数学教材为依据,将方格图的表现形式、数学本质以及在培养学生数学学习能力等方面所起到的数学价值进行系统地剖析和总结;同时将方格图在人教版教材中的编排情况进行梳理及归纳,从绘制图形、统一度量、数的认识与运算、总结和推理四个方面诠释方格图在教学中的具体应用及研究启示。

As an intuitive form of mathematical learning tool,the grid chart combines the interest of the subject with the interest of learning and has the effect of helping students improve their ability to learn mathematics.Based on the primary school mathematics textbookspublished by People's Education Press,this article systematically analyzes and summarizes the representation of the grid graph,the nature of mathematics,and the mathematical value it plays in cultivating students'ability to learn mathematics.The arrangement of textbook is combed and summarized,and the specific application and research implications of the graph in teaching are explained from such four aspects as drawing graphics,unified measurement,understanding and operation of numbers,summarization,and inference.
