The Stereognostic Bag Activity 3, Identify The Object

This sensorial video lesson, 3rd in the series, is designed for 3-6-year-old children. This lesson is designed to promote the development of the stereognostic sense in children at an early stage.

Using all of the senses is one of the core elements of Montessori pedagogy. According to Dr. Montessori, “sensorial experiences begin at birth.” 

Children love playing guessing games. They use their senses to study their environment. With the help of sensorial activities, children absorb and learn information that helps them classify their surrounding environment. It gives the child the ability to adapt to and thrive in that environment. 

“It is exactly in the repetition of the exercises that the education of the senses exists; not that the child shall know colors, forms or qualities, but that he refines his senses through an exercise of attention, comparison, and judgment.” The Absorbent mind

Thus, creating an environment in which children learn using more than one sense helps them remain engaged and retain their learning.

What is the Stereognostic Sense and Purpose of the Mystery Bag Activity?

The stereognostic sense is the capability of recognizing an object without seeing, hearing, smelling, or tasting it. It is also known as tactile or kinesthetic sensibility. A prevalent example of using the stereognostic sense is finding and turning off the alarm clock half asleep.

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.
