Science of Reading

The Letters & Sounds program provides complete continuity for teachers through its fidelity to the original Letters & Sounds framework and progression. It is one of the only Science of Reading programs to extend from Pre K - Grade 2 (Phases 1 to 6), and is the most comprehensive program with over 500 decodable readers and 2000 pages of daily lessons. Further, it extends Letters & Sounds through innovative supplementary resources, such as speech marks (for phonemes) and sound buttons (for graphemes).
