This report is concerned with the formulation of a sequence for the spelling-to-sound correspondence rules that cover the 1- and 2-syllable words in the speech comprehension vocabularies of 6- and 9-year-olds. One major function of the rule sequence is to serve as a basis for developing reading instruction materials for the sequence and content of phonics instruction, the selection of vocabulary consonant with the rule sequence, and the designation of a sight-word vocabulary. A second broad function is to generate materials for empirical studies on the acquisition of word attack skills. The sequence, including organizational guidelines and rationale for sequencing decisions, and the background and supporting data used to construct the sequence are presented in the report. A bibliography is included. (WB)
