Abacus is a promising aid for the Blind to learn and calculate mental arithmetic operations. It teaches the Blind Abacus learners to perform mental arithmetic calculations efficiently with ease and accuracy, but without a need of watching the bead movements on the Abacus instrument.


Abacus can be learned by using both the hands on the instrument and feel, observe and move the beads on the frame. This ensures consciously utilizing the brain. The touch of beads on the finger tips sends sensors and directly activates both left and right sides of the brain. This helps in performing mental math with high level of attention. 


Cranmer Abacus 


We all are already aware about the fact that Abacus has been in use for centuries to learn arithmetic. Even in today’s generation it is being used in the digital computers for processing large and complex calculations. With the widespread applications of Abacus device, it was also modified to be used by the Blind. This modified Abacus was then called Cranmer Abacus. This Abacus was named after its inventor Tim Cranmer who had transformed ancient Abacus to be used by the Blind people. Unfortunately, the Abacus which is used by the sighted people does not suit the need of those who are blind, and so was the reason for the invention of Cranmer Abacus.


Blind learners still make use of the Cranmer Abacus to perform arithmetic calculations like addition, subtraction, multiplication, division, square root and cube root. A rubber or some soft fabric is used behind the beads of Abacus to restrict their spontaneous movement. It is invariably used by the schools for blind to teach calculations to the students’ right from the early grades. Abacus helps the blind and visually impaired students to compute long and complex mathematical problems with the required speed. Also, the knowledge of using Abacus reaps benefits for a lifetime to the students. 


Skills incorporated in Blind students through Abacus


·         Learns basics of all arithmetic operations

·         Understanding of the concepts and methods

·         Mastery in simple and complex problems

·         Good knowledge about the place values

·         Set and clear the numbers on Abacus instrument

·         Use the correct fingers like normal students 


Can you imagine the applications of this ancient tool i.e. Abacus serving the needs of different people in the olden and modern times? The tool has been modified, rather simplified, as per the requirements in different ages. In the modern times, it is proven as a means of brain development in small children of 4 to 14 years.
