Martha Speaks Story Maker from PBS is FREE! Kids can create eight different interactive stories with this educational app based on the 1990s book by Susan Meddaugh. Martha is a dog who can speak as a result of eating alphabet soup. She is the narrator of the stories that your child creates. Kids choose a who (character), a where (setting), and several whats (more characters and objects) to move the plot along. The app presents 128 different vocabulary words that are reinforced in the “word bone zone” which is found at the end of each story. Thanks PBS for another great educational app for young kids!!
