In the Stereognostic sense exercise ,the child learns to feel objects and make recognitions based on that what he feels.Montessori recognized that while the eyes can perceive difference in size and form,the understanding is heightened when the hand is also engaged .She believed that the hand was the direct link to the brain.
The understand what a curve really is,you have to feel it and experience it.Children encour>ged to look objects while touching them .They are also encouraged to touch them with closed eye or a blindfold in order to experience them much in the way a blind person would .
