Books in A Dell yearling book series

From the age of a year and a half, Helen Keller could not hear. She could not see, and she did not speak. She lived in a dark and lonely world--until Annie Sullivan came to teach her. Annie traced letters and words in Helen's hand, and made Helen realize she could " talk" to people. Eager to make up for lost time, Helen threw herself into her studies. She decided to teach others about the special training deaf and blind children need. Helen traveled all over the globe and raised money to start up schools for deaf and blind children. Her courage and her determination to help others conquer the odds against them earned her the respect and admiration of the world.
