Our Academy lesson plans for Geography reference specific National Geographic articles for each grade level. National Geographic has many thousands of articles which we have culled to select the most excellent and appropriate ones for each of our grades. We use National Geographic articles for our geography program in grades 3-12th. The geography program correlates with our history program for each grade level. National Geography has added all their magazines to an online archive. The archive is incredibly easy-to-use and the articles and pictures are very clear. This is an incredible deal for a family! Here is a link for more information to subscribe to the archived magazines.
