Physical Description: Wooden abacus. Large, rectangular wooden frame. Another piece of wood extends horizontally within the frame, about 1/3 of the way down from the top. Eleven thin metal rods extend vertically from the top of the frame to the bottom. In the upper third of the frame, there is one wooden bead on each metal rod; in the lower two-thirds of the frame, there are four wooden beads on each rod.

History of Object: Abacus was used by Blind Services division of the Kansas Department of Social Rehabilitation Services (now Kansas Department for Children and Families). In Spring 2015, the department moved from the Docking building to a location on Kansas Avenue in downtown Topeka. They donated items that they no longer used to the museum. Abacuses are commonly used by the blind to learn mathematical calculations. This abacus is unlike those typically used by the blind, as it lacks a cloth or rubber backing to prevent the beads from moving when not being manipulated by the user.

Date: Between 1960 and 1990
