Cube Root Blocks
Chicago: c. 1870s
Oak and brass [IF YOU DON’T THINK IT’S OAK, CHANGE TO WOOD — IT JUST LOOKED LIKE OAK TO ME]
6 x 6 x 6 inches, overall

Set of 13 wooden blocks for classroom demonstrations of how to determine cube roots in mathematics. The blocks in various sizes can be used to visually determine the cube root of different numbers. The blocks fit inside a varnished wooden box with brass hinges and a brass hook clasp. An advertisement for A.H. Andrews school supplies in an 1873 publication lists Cube Root Blocks.

The use of cube root blocks in mathematical instruction was explained in an 1861 manual published by a different firm, the Holbrook School Apparatus Company (see References below).
