ABSTRACT:
An educational teaching toy for teaching a child the names of various objects. The toy comprises a card holder for holding a card having a visible picture of an object, and adjacent thereto aligned spaced-apart letters defining the name of the object. A slider covers the name, and if the child does not know the name of the object, the slider can be moved in increments across the name from one end thereof to the other to expose the letters one at a time to assist the child to identify the object. A double sided laminated card having letters that are visible only when the card is back-lit is also described.
