Montessori believed that “sensorial experiences began at birth. Through his/her senses, the child studies his environment. Through this study, the child then begins to understand his environment. The child, to Montessori, is a “sensorial explorer”.”

Montessori Materials are designed for young children's refinements of senses.

Sensorial materials include pink tower, brown stair, tasting exercise, cylinder blocks, even sandpaper letters' from language area are all sensorial based learning materials.
