Bob Books Set 1: Beginning Readers teach a child letter sounds with Bob Books Set 1! With four letters in the first story children can read a whole book. Consistent new sounds are added gradually until young readers have read books with all letters of the alphabet (except Q). Short vowels and three-letter words in simple sentences make Bob Books Set 1 a fun confidence builder. Bob Books Set 2 continues to build reading skills. Use of three-letter words and consistent vowel sounds in slightly longer stories build confidence. Children love the hilarious (and sometimes mischievous) stories and pictures. These twelve books, filled with fun, drama, and surprise keep interest high for even the youngest readers. For grades K-1. Paperback book collection. Bob Books Set 3 Children progress gently into the next steps of reading. Consonant blends, endings, and a few sight words advance reading skills and create more complex stories. Use of word families make longer stories more manageable. Children love the eight books and hilarious pictures. They delight in two fun-to-do activity books. For grades K-1. Paperback book collection.
