My Travel Map*
Although I am not a worldly traveler, I saw Paul Glazowski make a reference to this Simple Map Generator on the Mashable blog and it suggested that I should map out the places I have visited. I did so and the resulting map is embedded above. It actually lists all 215 countries (yes, I counted them) on seven continents and all that I had to do was click on the checkbox to select a country. While simple, this utility has an incredible potential for allowing students to "color in" maps for a variety of applications.
This Google Maps/Earth hybrid that is hosted by 29 Travels can be used to chronicle one's travels or visually identify the groups of countries or create comparative maps that can be used to document chronological change. This is a simple though effective answer.
How do you envision using it in your educational setting?
*You might note that this map is not embedded in this posting. I tried it, but it didn't format properly and took too long to load. SOOOO, I simply included a screen capture of the map and then linked it to the original map.
