Teaching Research on "Understanding of Graphics"——Taking "The Understanding of Triangles" as an Example

小学阶段关于图形的认识主要分平面图形和立体图形。小学数学教师能够正确理解和把握课程标准,是进行有效教学的前提;能够梳理'图形的认识'内容主线,并分析特点,掌握基本教学策略,是完成教学实施和教学目标的重要条件。以三角形的认识为例,探讨'图形的认识'教学策略研究。

The understanding of graphics in primary school is mainly divided into plane graphics and three-dimensional graphics.Primary school mathematics teachers can correctly understand and grasp the curriculum standards,is the premise of effective teaching;To be able to sort out the main line of'Understanding Graphics',analyze the characteristics and master the basic teaching strategies is an important condition to complete the teaching implementation and teaching objectives.Taking the understanding of triangle as an example,this paper discusses the teaching strategy of'understanding of figure'.
