Here's an easy way to teach latitude and longitude. The teacher should model each of the following steps which only takes about 10 minutes.

## Steps

- Use a large wall map or overhead map.
- Create a latitude/longitude chart on the board. See Related Features below for an example.
- Hand out blank charts like the one on the board for students to complete with you.
- Select three cities to demonstrate.
- For Latitude: Find the equator. Determine if the city is north or south of the equator. Mark N or S in the chart on the board.
- Determine which two lines of latitude the city is in between.
- Show how to determine the midpoint by splitting the difference between the two lines from step seven.
- Determine if the city is closer to the midpoint or one of the lines.
- Estimate the latitude degrees and write the answer in the chart on the board.
- For longitude: Find the prime meridian. Determine if the city is east or west of the prime meridian. Mark E or W in the chart on the board.
- Determine which two lines of longitude the city is in between.
- Determine the midpoint by splitting the difference between the two lines.
- Determine if the city is closer to the midpoint or one of the lines.
- Estimate the longitude degrees and write the answer in the chart on the board.

## Tips

- Emphasize that latitude always measures north and south, and longitude always measures east and west.
- Stress that when doing the measuring, students should be 'hopping' from line to line, not dragging their fingers along one line. Otherwise, they will be measuring in the wrong direction.
