Whole Phonics Early Level 1 Series are designed for students who know all the consonant and short vowel sounds. New readers feel empowered because they can sound-out unfamiliar words without guessing and steadily build their reading skills. These books are completely “decodable” meaning that they use simple words and only short vowel sounds as the first stepping stones into reading. Decodable readers series slowly progress into more complex reading concepts moving from simple one-syllable words (fan) to multisyllabic words (fantastic).
