I made this crossword puzzle using the website The Teacher's Corner to teach/review important vocabulary and concepts from Ch. 10 of the AP World History textbook THE EARTH AND ITS PEOPLES. The chapter covers East Asia from 400 AD/CE to 1200 AD/CE, including a lot on the Tang and Song.
The crossword puzzle contains a word bank. It is most relevant to the third and fifth editions of the textbook, since those two have generally the same chapters, content, etc. And in any event, there's a word bank.
