1. A clock useful for instruction in how to read time, comprising:

  • a face;

    two sets of numbers positioned radially about the face at first and second distances, respectively, from a center point of the face, wherein the second distance is further away from the center point of the face than the first distance;

    an hour hand and a minute hand attached to the face at the center point and extending therefrom to the first and second sets of numbers, respectively;

    the first set of numbers including consecutive integers one through twelve, and the second set of numbers including consecutive integers zero zero through fifty-nine;

    wherein the face is divided into twelve equally sized segments, each segment comprising an area defined by a thirty degree angle beginning along a line extending vertically from the center point of the face to a top of the face, representing a zero degree line, and proceeding in a clockwise direction about the face;

    wherein the segment defined by the area from thirty degrees to sixty degrees contains the integer one from the first set of numbers and the remaining numbers in the first set of numbers are arranged consecutively in a clockwise direction about the face;

    wherein a portion of each of the twelve segments is further divided into five equally sized sub-segments, each sub-segment comprising an area defined by a six degree angle beginning along the zero degree line and proceeding in a clockwise direction about the face;

    wherein the sub-segment defined by the area from zero degrees to six degrees contains the integer zero zero from the second set of numbers and the remaining numbers in the second set of numbers are arranged consecutively in a clockwise direction about the face;

    the hour hand is sized to have a length sufficient to extend from the center point into a first band containing the first set of numbers, and the hour hand and the first band are colored a first color;

    the minute hand is sized to have a length sufficient to extend from the center point into a second band containing the second set of numbers, and the minute hand and the second band are colored a second color different from the first color; and

    adjacent colored blocks positioned on the face,wherein the left-hand block is colored the same as the first band and the hour hand, and the right-hand block is colored the same as the second hand and the minute hand in order to provide a visual association between the hour hand and the corresponding number contained within the first band representing an hour of the day, and between the minute hand and the corresponding number contained within the second band representing a minute of the day for enabling the user to determine the time in digital format.
