Apparatus and method to aid in the teaching of the concept of time
 A time teaching aid for teaching the concept of remaining time and elapsed time comprises a stationary face with a plurality of numerical indicia marks arranged around the face in a generally clockwise pattern, and successive indicia marks decreasing in value in a clockwise direction from a twelve-o'clock position. A rotating face rotates in the clockwise direction on the stationary face and exposes a portion thereof in front of the stationary face during rotation. A time hand rotates in synchronization with the rotating face and points to the numerical indicia marks on the stationary face. The rotating face exposes an ever decreasing portion thereof during clockwise rotation and the time hand progresses in a clockwise fashion from the twelve-o'clock position, through the numerical indicia marks, and back to the twelve-o'clock position, such that the ever-decreasing exposed portion corresponds to the time hand pointing to decreasing values of the numerical indicia whereby to simultaneously indicate to a viewer the decreasing time remaining both proportionately and numerically on the stationary face.
