Stereognosis : does it sounds familiar to you ?
Stereognosis, or tactile gnosis, is recognizing and identifying the characteristics of an object only by soliciting touch (tactile perceptions) as well as the position, weight,… (proprioceptive information) of an object.
What’s the point ?
Each of us, on a daily basis, often mechanically uses our ability to use or recognize objects without seeing them.
It is the handle of the fork that we take without looking at it, the keys that we seek in the pocket, …
Tactile discrimination, motor control, etc. are thus developed and allow ease in everyday life and the ability to then perform more complex actions.
Early detection of difficulties in these areas will then allow a specialist to provide appropriate interventions.
The mystery bag is one of the tools for developing stereognosis.
But… what is this mystery bag?
In the shape of a T-shirt but closed in its widest part by a zipper and sewn for the shortest part, the mystery bag has two sleeves in which the hands are introduced.

Having previously entered the widest part of a GOSTOP board (with an adhesive pad) and, for example, the pieces of a tangram, the player must recognize the pieces by touch and match a model on this board without seeing pieces.

The adhesive pad on which the player positions the pieces avoids an untimely movement of the pieces, which allows the realization to be removed from the mystery bag without the pieces moving.
The board defines the playing surface and also facilitates tactile tracking.

The mystery bag can of course be used for many purposes related to tactile activities and be seen as an additional playing occupation to the Montessori curriculum.
For instance, during a math lesson, recognize the geometrical shape only by touching.
