Ancient Abacus Math’s Tool Used in Modern Times
The
Abacus provides countable beads for children to visualize numbers on a base-10
system. The children learn Abacus Math’s by manipulating those beads to perform
arithmetic calculations such as addition and division.
Etymology
The
word is derived from the Greek word ‘abax’, meaning “calculating board” or
“calculating table”.
Chinese Invention
The
first Chinese Abacus was invented around 500 B.C. The Abacus, as we know it
today, was used in China around 1300 A.D.
Usage
It is
still commonly used today across certain Asian communities.
First Computer
Often referred to as the first computer, the Abacus is an instrument
used to add, subtract, multiply and divide, to calculate fractions and square
roots.
What is Visual Math?
Visual math is the essential building block that replaces the
physical Abacus in the child’s mind. As the children gradually learn to visualize
the Abacus in their mind (virtual Abacus), they learn to calculate mathematical
problems using the principles of the Abacus, without the use of the physical
tool.
