If you have done graphing (x,y) in math class, you have already done latitude and longitude.

3. Latitude Lines – grid lines that run east-west on the earth (side-to-side). These lines measure the degrees north or south a location is. (Sometimes called parallels.)
Longitude Lines – grid lines that run north-south on the earth (up and down). These lines measure the degrees east or west a location is. (Sometimes called meridians.)
Equator – 0 degree line of latitude
Prime Meridian – 0 degree line of longitude
