Here is a belated review of Seabird by Holling C. Holling. I loved the story, (I found myself tearing up at the end) but I had a hard time gleaning much geography from it. Everything I've read from other CMers who have read it, raved about all the geography nuggets in it; so I kept thinking, "What am I missing?"
I think the only thing Anna got from it was what the equator is. However, through coloring the map, she got a pretty good idea of what Continent is which.
And speaking of that; I am very excited about studying Marco Polo this year. I have always been fascinated with him and his story, so I can't wait to share that with Anna. I think that is the best thing about homeschooling. Getting to share your passions and interests with your children, and see them take their own things from it.
