A compass rose shows the four cardinal directions and four ordinal (intercardinal) directions. Knowing them helps you describe where places are relative to each other.

Memory tip: "Never Eat Sour Watermelons" (N, E, S, W going clockwise).

Many maps use a grid system to help you find specific places. Rows are labeled with letters (A, B, C...) and columns with numbers (1, 2, 3...).

1. Find the row letter along the left side of the map.
2. Find the column number along the top.
3. The grid square where they meet is your coordinate (e.g., B3).

Every map uses symbols and colors to represent real features. The legend (also called the key) explains what each symbol means.

• Blue lines or shapes usually represent water (rivers, lakes).
• Green areas often indicate parks, forests, or vegetation.
• Dots or stars mark cities and towns.
• Dashed lines may show trails or secondary roads.
• Special symbols mark airports, hospitals, or landmarks.

Always check the legend first before interpreting any map.

A map scale shows the relationship between distances on the map and actual distances on Earth. It lets you estimate real-world measurements.

• Use a ruler to measure the map distance in centimeters.
• Multiply by the scale to get the real-world distance.
• Answers within 10% are often accepted for estimation tasks.
