TRY MULTIPLYING 342 by 246. It would need some solid arithmetical patience. But, with a coloured abacus in hand, a child could deliver the result mentally in few seconds. Abacus, a Chinese instrument, has traditionally been used for accelerating the calculations.
The modified Abacus of the 16th century based on Decimal scale has beads of the same colour. Ravindra Agrawal, Director Gyan Sagar Institute of Vedic Maths, Bhopal has innovated a ‘modified’ abacus with different colour beads. Such an abacus with ten different coloured beads has been designed probably for the first time in the world. Such a revised abacus is especially useful for children from KG to 8th standard.
“The different colours will make a quantitative leapfrog in enhancing mental calculations. It can bolster the memory and concentration prowess by almost 30 times”, Agrawal told the Hindustan Times. Agarwal has applied for a patent for modified abacus this month.
When we try to learn through a photographic memory, the results could be more lasting, he said adding “It can heighten the multidimensional thinking process.”
Agrawal further said, “In the old one coloured abacus the child had to remember on which cord how many beads are on top and how many are below. In the modified abacus each digit has a specific colour and so the child has to just memorise the colour of the last bead on the cord.”
Elucidating the details of the new version he said one to ten digits had a specific colour with a specific mental rhyming formulation. Agrawal said that he had ‘linked’ the memory technique of Harry Lorren with the abacus. Such a co-relation of memory technique with abacus is being done probably for the first time in the world.
“In the modified abacus with coloured beads there are 23 rods like the original one. The only difference lies in the colour, which can boost the mental calculation ability of a child,” he said.
But before actually mastering the art of ‘quick mental calculation’ the child has to learn the practical aspect for few months. So, arithmetical calculations are actually not as ‘boring’ as they sound!
