The complete card set for the Geometric Cabinet, providing the three levels of geometric shape representation — filled silhouette, thick outline, and thin outline — that scaffold children's visual discrimination from ages 3 through 6. These cards extend the cabinet work independently of the cabinet itself, allowing children to match, classify, and eventually identify shapes without the physical insets as a reference. A well-worn set is a sign of a well-used cabinet, and having a clean replacement set on hand keeps that sequence uninterrupted.
