This one is an experiment, so it's free for a limited time. Instead of doing a usual thinking/writing assignment at the end, I put a common core assignment. I thought I'd try it out and see if it works in one of my video guides. At present, it requires students to look up migration in their textbooks, do some research, and compare the two.
Let me know how you like the format, particularly those of you who are familiar with my past work.
My only request is that, if I end up changing them and you hate them deeply, you alter your review to address the new product (when/if I change it).
