Patent ID: 7121833

Claim:
A method for teaching the concept of beginning time to a student comprising the steps of: providing a clock face having a minute hand and an hour hand pivotally mounted thereto, said hour hand being connected to said minute hand such that pivotal movement of said minute hand about said clock face causes said hour hand to pivot synchronously therewith to designate a progression of hours, whereby said minute hand and said hour hand are selectively positionable to display a time of day; providing an elapsed time display having a releasable connection connected to said minute hand; pivoting said minute hand about said clock face to position said minute hand and said hour hand to display a selected ending time of day; actuating said releasable connection such that said elapsed time display resets to an initial position corresponding to said ending time of day; selecting a desired elapsed time; asking a student to calculate a beginning time resulting from said desired elapsed time subtracted from said ending time of day; verifying a result reached by said student by pivoting said minute hand and said hour hand from said ending time of day to a beginning time of day at which said elapsed time display has moved from said initial position to indicate said elapsed time, wherein said verifying step includes the step of pivoting said minute hand in a counterclockwise direction, whereby said elapsed time display moves in a counterclockwise direction; and comparing said beginning time of day with said calculated beginning time.
