Inspired by the best-selling novel ''The Da Vinci Code,'' this imaginative cross-curricular resource is the perfect way to reinforce basic grammar skills as well as introduce the study of United States presidents to your class. A short biography is included for each featured president that contains secret, embedded information. Students must study the biography and crack the code to answer a set of worksheet questions. It is within these hidden codes that students will practice punctuation, spelling, parts of speech, and a variety of other valuable language arts skills.
