This case contains 610 cards for use with any Orton-Gillingham based approach to reading instruction. The cards are divided into 43 groups of phonic sounds. Single words and detached syllables are used to exemplify the important patterns and generalizations found in reading and spelling. The cards can be used for decoding practice, to introduce spelling rules and generalizations, or for dictation. They are organized sequentially beginning with CVC words and moving on to spelling generalizations, syllabication, and word structure. One case per student is recommended.
