In response to declining math skills among their students, some Japanese schools are bringing back an ancient calculating device - the abacus.
At the other end of Eurasia, Lao-tzu, Chuang-tzu and the followers of Confucius elaborated Chinese thought; the abacus and blast furnace were invented; and the Grand Canal was begun.

“This provides a new template for disclosure ,” he said. “Entities putting products [like ABACUS] out are now on notice.”

An abacus is essentially an array of beads threaded on string or held in grooves, with each row representing a different digit.
When students mastered the abacus, they developed more confidence in their ability to do math.
