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.
