This document outlines a 7-day unit plan for a 2nd grade class on the regions of the United States. The unit includes 4 lessons: 1) an introduction where students label states on a map and learn there are 7 regions; 2) learning the names and characteristics of each region; 3) conducting research in groups on a assigned region; and 4) presenting their findings to the class through posters and a puzzle map activity. The lessons aim to help students understand the basic geography of the US by learning about its regions and the states within them.
