This website is invaluable for any educator trying to teach about the expansion of Chinese Dynasties. This interactive map gives you many options on the type of map you can choose to show your students. If you want to focus on comparing two dynasties you can chose both dynasties and compare their relative sizes. If you want to speak about important geographic features that came to influence the economy or political advancement then you have the choice to showcase rivers, topography, the great wall of China, etc. This is a great companion for textbooks because you can use it to supplement/scaffold a lesson.
