I use this unit for my 8th Grade US History Classes. It includes 5+ days of Introduction to Geography and an explanation of 4 more days when I teach my kids how to memorize the 50 states on a map. I think a variety of grades could use these materials, it would just require more or less time depending on your students' levels.
-5 Themes of Geography
-Continents & Oceans
-How to Use a Map
-Study guide, test, AND key
-50 states map with instructions on how I teach them to my classes
