#### Counting us Fun on an Abacus

# Ancient Tool Actively Used in Modern Times

# The Abacus provides countable beads for children to visualize numbers on a base-10 system. The children learn to manipulate those beads to perform arithmetic calculations such as addition and division.

# What Is An Abacus?

# 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 visualise 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.
