A Peek Inside the Lesson
This is the real lesson text your child hears, read aloud by a friendly voice.
Mapmakers cover Earth with imaginary lines to give every place an 'address'.
Lines of latitude run east-west. The equator is 0° latitude.
Lines of longitude run north-south, from pole to pole. The prime meridian is 0° longitude.
Where a latitude and a longitude cross, you get coordinates, like a grid square on a map.
Ships, planes and phone maps all use coordinates. GPS uses satellites to find yours!
