Abstract: A display device for teaching reading and writing includes a base member made from a blank cut from a sheet having a printed face. The blank is folded and slitted to define a guide collar having an unobstructed display area and an adjacent variable display area. Opaque and transparent display members are mounted in the collar for movement relative to one another and relative to the base member. A representation of a letter of the alphabet appears on the unobstructed display area and on part of the transparent display area. The variable display area has a representation of an object associated with the shape and sound of the letter. The opaque display member has a masking portion with a representation of a clue suggesting the object, and an additional display area having a representation of a motor plan for forming the letter. The display members are moved to employ different display modes including the object or the clue with and without an overlaid representation of the letter.
