These are not my ideas. I have saved ideas for several years and these are some that I thought you might be able to put to good use.
READING AROUND THE WORLDS… --- To move from country to country you had to read so many pages.
http://www.lcms.org/pages/internal.asp?NavID=9522 stamps for each country.
http://www.sacredheartschoolsuffern....n/Reading.html this web site has reading logs for each month
teach the fifty states by singing a song. The children love it and sing it every day. It took us about 2 weeks of singing everyday to learn it by heart. It's the fifty states song. There is a web site that has the lyrics and the tune.

Post a picture of "Person of the week" someone from history, current events, politics, etc.. and give some clues about that person. Students name the person and write a couple sentences about the person, or what their significance is. Use a state or country for your room.
****And Scholastic's books of history plays are pretty good, too. I did a Columbus play and one about the White House when the British burned it.
Your theme sounds wonderful.
