Description :-
The Stereognostic Bag: Same Shape Diff Sizes is a Montessori material designed to develop
the tactile sense and enhance a child’s ability to discriminate between sizes through touch alone.
This material consists of a set of 6 pairs of spheres, each pair varying in size but having the same
shape. The spheres are wrapped in a bag, and the child’s task is to feel the objects inside the bag
and match the spheres based on size.
The spheres are made of wood for durability, and each set contains 6 pairs of spheres, where each
pair has a larger and smaller version of the same shape. The child does not know the sizes
beforehand and must rely solely on their sense of touch to identify and match the spheres that
belong together.
Stereognostic Bag: Same Shape Diff Sizes
The main goal of the Stereognostic Bag: Same Shape Diff Sizes is to challenge and develop the
child’s sense of touch, size discrimination, and creative thinking. By manipulating the spheres,
children are encouraged to:
Refine their tactile perception by feeling the objects and determining which spheres are the
same shape but different sizes.
Enhance their ability to recognize size differences and match objects based on tactile cues.
Develop creative thinking as the child explores different ways to solve the challenge of
pairing spheres of varying sizes.
Strengthen cognitive skills such as comparison, classification, and problem-solving.
