National Geographic Maps: Tools for Adventure is the best everything-map site I have seen. The site was created by the Children's museum of Indianapolis. Maps are presented as the keys to adventure. Students learn to use maps to find their way, share information, look at patterns, and solve problems. There are six excellent interactive games for students to practice putting their math skills to use. Students can explore a pyramid by guiding a robot to hieroglyphs, find sunken treasure, explore Mars, go on an adventure, see GIS in action, and visit Adventure Island. I love the realistic feel of these games, as students explore and guide robots, they get a "live" video feed of where they are navigating. On the National Geographic Maps: Tools for Adventures site, you will find information about the Indianapolis exhibit, how to use maps, related map links, and lesson plans. This is one of those websites that my description just won't do justice to, be sure to check it out!
