The Primary Phonics "Mac and Tab" Storybook Set has been well known in the Montessori Community as the most systematic reading series since 1968, and it remains the best! This phonics-based early reading program facilitates individualized instruction through flexible, skills-based workbooks and storybooks that correspond to students’ ability levels. Children learning to read, enjoy the satisfaction that comes from reading a whole book independently. The Primary Phonics illustrated storybooks series features books that are each approximately 16 pages long and which use words containing the phonetic elements taught in (not-included and sold-separately) workbooks.
