Ohhhhh my! The abacus’s history is so rich and a base learning tool to many contributing members of history.  “The abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing arithmetic processes. Today, abaci are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere. ” (thanks wikipedia!) I’d like to think that this would be a great conversational piece for all ages. Sells for $40 on Snoozer Looser.
