A Fantastic Demonstration Tool

Giant sorobans are used to demonstrate the soroban to an entire class of students at once. The giant soroban is especially useful for beginners who want to see how the soroban works.

It is an essential tool for teachers who want to teach soroban to their students, as it allows a live demonstration of how the soroban operates in front of the whole class.

Demonstrating addition, subtraction, multiplication, and division becomes effortless. This can be difficult to do effectively on a whiteboard.

The large size ensures that all children, including those seated at the back of the classroom, can clearly see the soroban beads.

It is best to use the giant soroban alongside individual abacuses to teach various calculations (addition, subtraction, multiplication, etc.) according to the soroban learning methodology.

The giant soroban is designed for vertical use, ideal for demonstration purposes.

For better visibility, we recommend teachers choose a soroban color that contrasts with the background where it will be used: if you use a blackboard, the white version might be the best choice for your classroom.

 

Soroban Methodology: Proven Effective

Learning sorobans offer many benefits for children:

  • Sorobans allow children to solve problems mentally without relying on written numbers like calculators.
  • Sorobans help develop logical thinking since children must visualize math problems to use them effectively.
  • Sorobans are lightweight enough to fit into children’s backpacks for soroban lessons outside of school hours.


Traditionally, the number of rows on sorobans is always an odd number.

In Japan, soroban lessons are a mandatory part of the elementary school math curriculum.

Sorobans have been in use since the 17th century. Merchants quickly noticed their sorobans were often misplaced, so they began making sorobans with a protective cover on top to prevent loss.
