Dr. Montessori strongly believed in training the senses which is why in a Montessori classroom, there is a section devoted to sensorial exercises. She developed many different materials for the enhancement of the senses, "The senses, being explorers of the world, open up the way to knowledge." (The Absorbent Mind, pg. 167)
We also present variations and extensions to the exercises Dr. Montessori developed. This one is called the Music Box game. A child sits in the middle of the group with her eyes closed. The music box is placed somewhere in the classroom. When she is told she may open her eyes, she uses her auditory sense to find the music box.
