The Stereognostic Bag (I834) is a drawstring bag designed for stereognostic sense activities, used to isolate the tactile sense by removing visual information during object identification or matching exercises. Intended for the primary environment, it supports sensorial refinement work and pairs naturally with geometric solids, small world objects, or classroom manipulatives across curriculum areas. Having a spare or alternate-sized bag on hand gives flexibility for simultaneous work across multiple children or small groups without interrupting the flow of the environment.
