Patent ID: 8238200

Claim:
A method of teaching multiplication tables, comprising the steps of: dividing a face of a timepiece into a central region and a circumferential region; selecting a first multiplier N, wherein N is an integer between one and twelve; displaying the first multiplier N in the central region; dividing the circumferential region into N annular portions; displaying a set of integers x N(y) about each of the N annular portions of the circumferential region, wherein y is an integer ranging between one and twelve such that x 1(1) to x 1(12) ranges between one and twelve to simulate a face of an analog timepiece, and x N(y) =x 1(y) +(N−1)×12; displaying at least a simulated hour hand and a simulated minute hand; positioning the simulated hour hand and the simulated minute hand with respect to an innermost annular portion of the circumferential region to indicate the present time; selecting a second multiplier M, wherein M is an integer between one and twelve; graphically identifying the second multiplier M in the N=1 annular portion of the circumferential region; visually indicating a sequence of clockwise steps made from the second multiplier M to the value of x N(y) equaling N×M, wherein if the product of N×M is greater than twelve, the sequence of clockwise steps follows a clockwise path to each multiple of twelve within a respective one of the N annular portions and continues into the next higher annular portion.
