For Cinco de Mayo, we did the Day in the Life of a girl who lives in Mexico (found under North America -> Mexico ->Day in the Life (Left sidebar). I usually just copy and paste the text into a word document and print it.
Most of the time, we get to do two paragraph readings as a group. I usually try to pick countries that are relevant in current events (like in the news or holidays). If not, I try to pick two countries that seem very different.
This can be useful for language too (comparing and contrasting is usually my favorite thing to do with these!).
