Abstract: The teaching clock provides a visual aid to enable children to grasp fundamental time relationships. The clock includes a base member having a concentric arrangement of minute numerals, a rotatable member mounted to the base member and having a window for selectively exposing the minute numerals during rotation and a cover for the base member having a concentric arrangement of hour markers. A minute pointer, fixedly attached to the rotatable member, is directed toward the window and the exposed minute numerals and an hour pointer is movable between the hour markers independently of movement of the minute pointer. The hour markers include individual marker pips for each hour and marker segments extending between the pips, the segments being color coded to correspond with the immediately counterclockwise marker pip.
