분류의 관점에서 초등수학 평면도형 고찰 

요약   

 In this article, we investigated plane figures introduced in elementary school mathematics in the perspective of traditional classification,

and also analyzed plane figures focused on the invariance of plane figures out of traditional classification. In the view of traditional classification, how

to treat trapezoids was a key argument.

 In the current mathematics curriculum of the elementary school mathematics, the concept of sliding, flipping, and turning are introduced as part of development activities of spatial sense, but it is rare to apply them directly to figures. For example, how are squares and rectangles different in terms of symmetry? One of the main purposes of geometry learning is the classification of figures. Thus, the activity of classifying plane figures from a symmetrical point of view has sufficiently educational significance from Klein's point of view.
