Abstract
A flip card apparatus is disclosed having a support for a ring binder spaced from one edge of the support and having equally spaced rings and a plurality of card decks, each card of each deck having punched holes for mounting on the ring binder and with indicia printed on the cards centered between the punched holes. The holes are spaced such that the number of complete holes is one less than the width of the card divided by the hole spacing. As indicia the cards can include letters, word prefixes, word roots and word suffixes, vowels or vowel sounds, consonants or consonant sounds, graphemes, phoneme mouth sequence pictures, raised pictures or Braille symbols. The corners of the cards may be cut. A support road is provided for insertion through a hole in the support under the ring binder. The support and cards can be constructed for contrasting color.
