FIAR has been fun for us. I am planning this year to use the titles set in different countries. The guide doesn't offer any geography instruction other than find ____ on a map and discuss capitals or landmarks etc. So we use the FIAR title as a jumping place for nonfiction geography or science books. (FWIW, I am really impressed with the art instruction in the FIAR guides.)
Books that we have read that you could look for at the library.
Story about Ping, set on the Yangtze River in China. So we watched "Wild China" documentaries, read books about China, ducks and cormorants.
Madeline, set in Paris. We read books about France, built a lego Eiffel Tower, watched a documentary on the Eiffel Tower, and made crepes.
Papa Piccolo, set in Venice. We learned more about Italy and cats.
Other books will lead into studies of Spain, Scotland, Japan, Russia.
