Miss Alaineus is such a cute book that is all about vocabulary. Sage, the main character, misunderstands the word miscellaneous, one of her vocabulary words that her teacher gives her. When Sage gets up in front of the class to spell the word miscellaneous, she spells is "Miss Alaineus". This, of course, is embarrassing to Sage when she becomes aware that she misspelled the word. The students called her Miss Alaineus for the rest of the day. Finally, the disaster turned into triumph. Sage dressed up as the Miscellaneus queen for the school's parade.
This would be good to use in grades 3rd & 4th. Students could choose a vocabulary word and create a costume with the word and its definition.
