ABSTRACT:
A board-type device for use in teaching children the alphabet, numbes, how to tell time, and the like. The device includes a disk-like, double sided chalkboard member and a ring-like frame member extending completely about the periphery of the blackboard member with the blackboard member rotatably mounted to the frame member. Alphabetic letters and the like are located about the frame member on one side thereof. Numerals and the like may be located about the other side of the frame member with the numerals arranged similar to a clock face. Pointers are attached to both sides of the chalkboard member whereby rotation of the chalkboard member will cause the pointers to point towards various specific letters and/or numbers and/or the like, etc. Indicia-bearing inserts are rotatably attached to the front and back surfaces of the frame.
