Have you ever used a compass? It’s a tool that helps us find directions. A compass shows four main directions called cardinal points: north, south, east, and west. It also shows in-between directions called intercardinal points: northeast, southeast, northwest, and southwest. For example, if you look at a map, you might say that the United States is southwest of Iceland. This helps us understand where places are in relation to each other.
Sometimes, we need to know exactly where a place is on Earth. That’s when we use latitude and longitude. Imagine a grid covering the whole world. This grid is made up of imaginary lines that help us pinpoint locations.
Lines of latitude run horizontally around the Earth. They are also called parallels. The equator is the main line of latitude and is at zero degrees. Other lines of latitude are at 15, 30, 45, 60, 75, and 90 degrees, both north and south of the equator. If a place is north of the equator, we write an “N” after its latitude. If it’s south, we write an “S”. These lines help us know how far a place is from the equator.
Lines of longitude run vertically from the North Pole to the South Pole. They are called meridians. The prime meridian is the main line of longitude and is at zero degrees. It runs through a place called Greenwich in England. Other lines of longitude are at 30, 60, 90, 120, and 150 degrees, both east and west of the prime meridian. If a place is east of the prime meridian, we write an “E”. If it’s west, we write a “W”. These lines help us know how far a place is from the prime meridian.
When we want to describe a place’s exact spot on Earth, we use both latitude and longitude. We always say the latitude first, followed by the longitude. For example, New Orleans in Louisiana is at 30 degrees north of the equator and 90 degrees west of the prime meridian. This is its absolute location.
Now, can you use what you’ve learned about latitude and longitude to find the absolute location of where you live? It’s like being a detective with maps!

Using a piece of paper and some colored pencils, draw a large circle and divide it into eight equal sections. Label the cardinal points (north, south, east, west) and the intercardinal points (northeast, southeast, northwest, southwest). Decorate your compass rose with colors and symbols. This will help you remember the directions and how they relate to each other on a map.
Work in pairs to create a treasure map of your classroom or school. Use imaginary lines of latitude and longitude to mark the location of a hidden “treasure.” Exchange maps with another pair and use their coordinates to find their hidden treasure. This activity will help you practice using latitude and longitude to find exact locations.
Get a large world map puzzle and work together as a class to put it together. As you place each piece, identify the latitude and longitude of a few key locations. Discuss how these coordinates help us understand where each place is on the globe. This will reinforce your understanding of how latitude and longitude work together to pinpoint locations.
Create bingo cards with different coordinates instead of numbers. As the teacher calls out a location, mark the corresponding latitude and longitude on your card. The first to complete a row wins! This game will help you quickly recognize and remember different coordinates.
Using a blank map of your city, mark important landmarks and their latitude and longitude. Share your map with the class and explain why you chose those landmarks. This activity will help you connect the concept of absolute location to real-world places you know.

[Narrator] The cardinal and intercardinal points on a compass are used to describe the relative location of places to each other. A compass displays cardinal points: north, south, east, and west; as well as intercardinal points: northeast, southeast, northwest, and southwest. For example, we could say the United States is southwest of Iceland.
To describe more specific locations, we can use the lines of latitude and longitude. These imaginary lines cover the world like a grid. Absolute location is measured in degrees of latitude and longitude. Lines of latitude, or parallels, are imaginary lines that run horizontally around the planet. The equator is at zero degrees. These lines represent 15, 30, 45, 60, 75, and 90 degrees north of the equator. Lines of latitude show how far a place sits north or south of the equator, so we write an N for locations north of the equator and an S for locations south of the equator.
Lines of longitude, or meridians, are imaginary lines that run vertically from the South Pole to the North Pole. The prime meridian is at zero degrees and runs through Greenwich, England. These lines represent 30, 60, 90, 120, and 150 degrees east and west of the prime meridian. Lines of longitude show how far places sit east or west of the prime meridian, so we write an E for locations east of the prime meridian and a W for locations west of the prime meridian.
On the opposite side of the globe from the prime meridian is the line of longitude at 180 degrees. This 180 meridian is also the basis for the International Date Line. When stating absolute location, the latitude, or position north or south of the equator, is always stated before the longitude, or position east or west of the prime meridian.
For example, this is the absolute location of New Orleans, in Louisiana. This means it sits 30 degrees north of the equator and 90 degrees west of the prime meridian. Can you use your knowledge of latitude and longitude to find the absolute location of where you live?
