Hopefully students have learned that maps are very
important. Maps are representations of the Earth's surface. Maps are
abstractions because they show simplified versions of surface features. They
are designed to show detailed information about a limited number of topics.
Maps are thus not pictures of the Earth’s surface. A map can show many
things that a picture cannot show. Maps look different in many ways from a
photograph of the Earth. Most maps are two dimensional representations of
the three dimensional surface of the Earth, and are drawn on paper.
Increasingly, however, computers are providing us with three dimensional

- Explain what a map is to the students. Emphasize to
them that maps are usually some kind of representation of the Earth, or
part of its surface, and that maps have a particular purpose. If you
have an atlas available, this is a good time to show it to the class.
Explain that it is a collection of maps to help people locate different
features or places.
- Have the students list the maps with which they are
familiar. They may think of unusual sources, such as maps in video
games. List the maps on the board.
- Have the students look at many different
representations of the Earth. Be sure to include maps, photographs,
and a globe. Ask the students to find the map, globe, or picture that
best represents the Earth. Unless you have an extraordinary flat map,
the globe is the most realistic. However, if you are trying to find
something in a city, a globe is not detailed enough. Flat maps, globes,
and photos all have their place.
the students to bring a "map" from home that they would like
to share with the class. Tell them that if they do not have a road map,
they can get a map from a newspaper, telephone book, or sometimes
advertisements from a local business. You may wish to create a map
display with the material that the students bring to class.
