National Geographic has great lesson plans

You can find lesson plans everywhere, and often they are free! Check out the National Geographic Xpeditions website. It includes lesson plans, activities, maps and geographic standards for all grades, K-12. Where else could you find better geography lessons than in National Geographic?

Here's an example of a lesson plan that I liked: The United States at Night. In the lesson, students hypothesize how the United States might look like at night based settlement patterns and other factors.
