Giant Soroban
A Fantastic Demonstration Tool
Giant sorobans are used to demonstrate the soroban to an entire class of students at once. The giant soroban is particularly useful for people using the soroban for the first time and who need a visual example of how it works. It is an essential tool for teachers who wish to teach the soroban to their students, as it allows for a live demonstration of how the soroban operates to the whole class. Demonstrating addition, subtraction, multiplication, and division becomes a breeze, which is not always easy to do on a whiteboard. The large size ensures that all students, including those seated at the back of the class, can clearly see the beads of the soroban.
It is advisable to use the giant soroban in conjunction with individual sorobans for children to teach various calculations (addition, subtraction, multiplication, etc.) according to the soroban methodology. The giant soroban is designed for vertical use, suited for demonstration. For better visibility, teachers should choose a color that contrasts with the background on which it will be used: if using a blackboard, a white version may be the best choice for the 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 can help develop logical thinking in children as they require visualizing math problems to use them.
– Sorobans are lightweight enough to be carried in children’s bags for soroban classes outside of school hours.
Traditionally, the number of rows in sorobans is always an odd number. In Japan, soroban lessons are a mandatory part of the mathematics curriculum in primary schools. Sorobans have been in use since the 17th century. It didn’t take long for soroban vendors to notice that their sorobans were being lost, so they began making sorobans with a false top to prevent them from being misplaced.
