Abstract
An educational game is provided and includes a transparent sleeve having a plurality of elongated compartments in which movable opaque slides are positioned. A set of transparencies are also provided and on each transparency there is a column of legends that are spaced so as to be in juxtaposition with a grip formed on at least one surface of the transparent sleeve. Thus, each of the legends, which may be in the form of questions or statements, are in alignment with one of the squares in the transparency grid. A projector is positioned so that the legends on the transparencies may be projected onto a surface such as a wall. As the opaque slides are withdrawn successive legends will be projected. The legends may be answered as part of a teaching technique or a game may be played with a plurality of individuals or teams with the time being a factor for answering the questions or identifying the legends. As the slides are pulled out further the questions or statements become progressively more difficult.
