The Baric Tablets were developed by Dr. Montessori as a way to develop the sense of touch and more specifically to make fine discriminations in weight. The child wears a blindfold to focus his attention on the weight rather than the color of the tablets.
Although there are three different weights of tablets, the two most contrasting ones are used to begin. We teach specific vocabulary such as "heavy" and "light" to describe the different weights and carefully place them on the fingertips of the hand. Here a child has completed this exercise and another child wishes to help place the tablets in the hand.
