ABSTRACT:
A teaching toy has a housing with a viewing screen located in the housing. Positioned behind the viewing screen is an indicia carrier located on rollers. A plurality of indicia is located on the surface of the indicia carrier. By rolling the indicia carrier on the rollers, different portions of the indicia located on the indicia carrier are viewable through the viewing screen. Associated with the indicia carrier and located in front of it between it and the screen are a series of cover members which can temporarily cover a part of the indicia which is exposed through the screen. Operator actuators are connected to the cover members so as to allow the cover members to sequentially move from a position wherein they cover the indicia to a position where they no longer cover the indicia. By sequentially utilizing the actuator members, a child utilizing the toy partially uncovers the indicia, allowing the child to guess what the total indicia will be. When all of the cover members have been moved from their covered position to their uncovered position, a further actuator is utilized to move the indicia carrier on the roller to expose new indicia through the screen.
