In the early 1960s, the Chicago firm of Playskool introduced this educational toy for children three to six years old, seeking to give them an early familiarity with numbers. It has two rows of relatively large rotating wooden rectangular blocks, each with a row of square rotating wooden blocks below. The larger blocks have problems in simple addition written on them, the smaller ones answers. The problems and correct answers are written in the same color of paint. The blocks move on metal rods that are attached at top and bottom to a frame. The frame is supported at the back by a collapsible metal stand. The frame is painted with a pattern of bricks on the side and a roof at the top.
A contemporary advertisement indicates that the toy cost $3.19.
