Hi Bethany,
This is a great lesson plan. China's "One Child" policy is definitely a topic that should be researched and learned about. As I said before, your lesson is well organized and has lots of detail. I liked the fact that on day 2 in "the creation and interpretation of the population pyramids", you give the websites for the data research. This allows teachers the option to have their students search on line instead of handing them printed information. The "ticket out" is also a god way of keeping students accountable. The only thing that I would add is on day 1, in the "getting started...prompts", I would also ask if they know the population of the U S. (310,300,000) they can compare this to China's population and have an understanding as to why there is a "One Child" policy.
Over all a great lesson!
