What is Stereognostic Sense?
A Stereognostic sense is the ability to perceive and recognize, through touch, the characteristics that allow identifying an object without looking, smelling, tasting, or hearing it.
It helps a child identify the shape, size, type of material, temperature, texture, etc. It is also known as tactile or kinesthetic sensibility.
What is a Stereognostic Bag?
The stereognostic bag is also called the mystery bag. It is designed to help children develop their ability to visualize objects using only their sense of touch. Children love this activity because it is both challenging and fun.
Usually, it is simply a non-transparent cloth bag or box with a hole/ opening for the child’s hands, through which they can touch and identify objects without looking at them.
The Mystery Bag is also used to reinforce the geometric solids from the sensorial area in the Montessori classroom.
