How do you know what a symbol means? Look for the box on the map called the map key. It is also called the legend.
Key idea
The map key shows each symbol and tells what it stands for. When you see a symbol you do not know, check the key.
Why it works
Different mapmakers draw different symbols. One map might use a tent for a campground, and another might use a triangle. The key is how the mapmaker tells you which is which, so you never have to guess.
Worked example: Using the key
On the map above, there is a blue shield with a star. What is it?
- Find the blue shield in the map key.
- Read the words next to it.
- The key says: Police station.
Answer: A police station.
Common mistake
Children often guess what a symbol means from how it looks. Guessing can go wrong: on the Hill Park map, the green triangle is a tent for the campground, and the gray one is a mountain. Always check the key first.
For the grown-up. Look at a real map together: a zoo map, a park map or a mall map. Find the key first, then go on a symbol hunt: "Where are the restrooms? Where is the snack bar?"
