Let's Talk Geography

Gr 3—7—This very brief introduction to maps and globes hits all the highlights, but by no means is a complete lesson. Hosted by one young lady and narrated by another, there are three main sections that can be accessed individually, or played together. "What Is a Map?" uses many quick images to introduce different types of maps and the map key. In "Grids and Directions," the compass rose is introduced and students are told about coordinates. In "Globes," the narrator explains that a three-dimensional shape more accurately represents the size and shape of the earth's areas, and the inevitable distortion of Projection maps is demonstrated for Polar, Equal Area, and Mercator Projection Maps. Lines of latitude and longitude, the Equator, Prime Meridian, and the International Date Line are explored on globes. The section in which certain places on the Earth are located by their coordinates is especially useful and well demonstrated. The "Fun Facts" that provide fascinating historical tidbits of information between sections are interesting. While the information flows quickly, terms are explained and illustrated by example, and certain key words appear onscreen as reinforcement. A fine basic overview to supplement a unit on maps and globes.—MaryAnn Karre, Horace Mann Elementary School, Binghamton, NY
