Beatrice wants to write the kind of letters that start with "Dear Somebody," but she only knows how to write letters like A B C T E R I E. Then her Nanny Hannah teaches her how to put the letters together to spell words, and Beatrice takes off on a spelling spree. She decides to start a Spelling Club at school, but no one signs up because spelling is B-O-R-I-N-G. In fact, the class decides to go on a spelling strike! Then Beatrice has a lulu of an idea and turns show-and-tell into show-and-spell starring her pet T-A-R-A-N-T-U-L-A-and soon everyone has caught the spelling bug.
