All-Star Readers are presented in carefully age-graded levels for beginning readers at each development stage. Level 1 (preschool to grade 1) features large type and short, simple rhyming stories. Level 2 (grades 1-2) uses smaller type and a larger vocabulary with multiple-syllable words. Level 3 (grades 2-3) uses high-interest nonfiction subjects, a richer vocabulary, and more words per page. Each book includes stickers, word activities, and tips from a reading specialist.
