Three series of cards that correspond to the figures contained within the Geometric Demonstration Tray. Each shape is represented by three cards depicting the shape as a thin outline, a thick outline, and filled in.

The purpose of this product is to recognize and match different representations of shape.

The geometric insets from the demonstration tray are first matched with the filled-in cards, with the thickly outlined cards when the child gains greater proficiency, and finally with the thinly outlined cards.
