Abstract

Abstract An educational device for teaching beginning readers how to read includes three independently rotatable discs. The first disc includes a series of word families; the second disc contains a series of word family windows through any of which any of said word families can be viewed, and an initial sound printed adjacent each of said word family windows; and the third disc contains a word window through which a complete word (i.e., an initial sound and word family) can be viewed, and an initial sound window through which one of said initial sounds can be viewed before the complete word is formed in the word window.
