I Am Helen Keller is an episode of Xavier Riddle and the Secret Museum.
Yadina becomes increasingly frustrated as she tries to read a book to Dr. Zoom, but has to keep stopping since it has words in it she doesn't know. Learning to read is SO hard - she feels like she'll never be able to do it. Xavier knows just what his little sister needs: To the Secret Museum! Our heroes travel back in time to meet someone truly incredible, who had to overcome a whole lot to learn how to do just about anything: Helen Keller. Watching Helen first learn what words are, then how to read, and finally how to speak, all in her own unique way, inspires Yadina to go home and try to find her own way to learn to read. Because, as Helen shows her, there are many different ways to learn.
Product placement: In the library, the Ordinary People Change the World book "I Am Jane Goodall" can be seen, suggesting that the series of books exists in the Xavier Riddle universe.
Helen's teacher Anne Sullivan is voiced by Emilie-Claire Barlow, who does Courtney on Total DramaRama, a show that Brad's VA, Wyatt White, also stars on. She also voices the Mermaid on another PBS show, Peg + Cat.
