This learning card 100 for counting and shapes presents a perspective view 1 that illustrates a polygonal column including one equilateral triangle prism, regular quadrangular prism, or regular hexagonal prism, and has a peripheral edge along the visible outline 2 of the perspective view 1. Preferably, the polygonal column is cube-shaped and the perspective view thereof is drawn with isometric projections. Both the front and the rear of the card preferably present the perspective views showing polygonal columns. The sides and/or the surfaces of the polygonal columns are preferably drawn with different colors for the front and rear perspective views. One side 63 of the polygonal column may be drawn with a different line from the lines drawn for other sides. One surface of the polygonal column may be drawn with a different color from the colors used for other surfaces. A perspective view may present a view wherein a plurality of the polygonal columns is coupled in such a manner that the surfaces of the columns overlap with each other, and the learning card may have a shape cut out along the visible outline of the perspective view.
