Based on the best research on how children develop reading skills, these twelve books introduce a carefully selected progression of letter sounds-starting starting with the easiest and most common. Each book helps build a young reader`s confidence with repeated examples of the letter sounds being focused on, as well as "words to learn" and "words to sound out." These books will readily appeal to Dora`s audience of beginning readers as they capture all of the familiar elements from Dora`s hit TV show, including her spunky personality.
