Teaching wheels

A teaching wheel comprising:

• a. a frame fabricated from a thin material and having a center and periphery, the frame defining a notch extending from the periphery toward the center;
• b. a problem disk superimposed on the frame and having a center coaxial with the frame center, the problem disk having a periphery terminating inwardly of the frame periphery and bearing a plurality of problem indicia thereon;
• c. an answer disk underlying the frame and having a center coaxial with the problem disk center, the answer disk having a periphery approximately coextensive with the frame periphery, the answer disk bearing answer indicia corresponding to each of the problem indicia on the problem disk, the answer indicia being located on the answer disk at locations adjacent the periphery thereof and outwardly of the problem disk periphery;
• and
• d. rivet means for mounting the problem disk and answer disk for rotation about the respective centers thereof to the frame center,
• so that the problem disk may be rotated relative to the frame to align a selected problem indicia with the frame notch and the answer disk may be rotated relative to the frame to display a selected answer indicia in the frame notch adjacent the selected problem indicia.
