National Geographic Xpeditions: online & offline geography activities and lesson plans
There are 2 ways for homeschoolers to use this website: parents can use the included lesson plans (grades 1-12 are represented) to teach about specific topics, or students can explore the virtual "Xpedition Hall" independently and learn about mapping and geography. The lesson plans are creative and use materials from respected scholars and artists. The Xpedition Hall requires reading, and is best suited for middle school age or older. The tasks in the Xpedition Hall emphasize understanding and applying geographic techniques and information, not rote memorization.
