Bob Books was developed as a step-by-step, book-by-book program to guide your child gently through the early stages of reading. Each level addresses a stage in a child's reading development: Level A introduces the alphabet with very basic three-letter words and short vowels. Level B adds longer words with short vowels and consonant blends. More complex stories in Level C include long vowel sounds and compound words. This carefully crafted, simple, and progressive approach to learning assures children success and confidence from their very earliest reading experience. Bob Books Fun is part of Level A, Set 2, which includes 12 books, 16 pages each. The focus is primarily 3-letter words, consistent sounds and sight words, and longer stories.
