Description

Not all calculators are created equally! Invented in the early 1600s by John Napier, this manually operated calculating device revolutionized multiplication using rods and a lattice frame. While the original Napier's Bones sets were made from bone, this reproduction is made of quality wood components. Base measures 7" x 7" and makes a perfect cover for the lattice frame and rods. Rods are made from 1/8" thick alder and are laser engraved. Two sets of rods are included (0-9) and measure 6" long. A brief background and instructions for use are included. A great way to challenge your math students, while providing a fun look at primitive technology! ~Deanne
