The document summarizes the first theme of geography, which is location. It discusses both absolute and relative location. Absolute location refers to a place's exact coordinates in latitude and longitude. Relative location describes where a place is in relation to other locations, such as east or north of another place. The document provides examples of using relative location to describe where Tamanend Middle School and Mr. Blair's desk are in relation to other landmarks. It concludes with an activity where students draw and hide geography battleships on a grid to practice the concept of location.
