The Cram US & World Discovery Roller Map Combo is the ideal classroom map set for your second or third grade students. This combo includes a world map and a United States map so you can teach both global and national geography with the same easy-to-u se system. These intermediate level maps are packed with all the most important details but won`t overwhelm your students. Each sheet shows a large colorful political map and an inset physical map a combination that helps your students understand the two main map representations. Lakes rivers cities and capitals are all easy to find since the straightforward legend uses elements directly from the map so kids can easily find and understand the information they need. The maps are printed on durabl e non-tear material that you can mark on while teaching to point out key features. A heavy-duty spring roller protects the maps while not in use and smoothly expands when needed; the backboard keeps the sheets flat so everyone can see.About CramCram has been bringing you the world since 1867.
