Each of the 5 themes of AP World are listed with accompanying big questions. Excellent source for referencing in the classroom as a poster, or printing out to hand out to students.
I was able to print a 24 X 36 poster version from Staples using this file, and the quality was excellent.
PLEASE NOTE: The big questions listed appear in an basic, no frills font. For an italic font, please see "AP World History Themes and Big Questions Poster V1"
