Understanding Map Keys and SymbolsActivities & Teaching Strategies
Active learning helps students grasp map keys and symbols by turning abstract ideas into concrete tasks. When they move, create, and compare, they see why symbols matter and how keys keep maps useful across different places and purposes.
Learning Objectives
- 1Identify and classify at least 10 common map symbols and their corresponding features from a given map.
- 2Explain the purpose of a map key in ensuring clear and accurate map interpretation.
- 3Compare and contrast the symbols used for the same geographical feature on two different maps.
- 4Design a new, clear symbol for a local landmark not typically found on standard maps.
- 5Evaluate the effectiveness of different symbols in representing specific geographical features.

Symbol Scavenger Hunt: Local Maps
Provide printed maps of the school neighbourhood. In pairs, students locate and list five symbols, noting their key meanings and sketching real-world matches. Pairs share one finding with the class, discussing variations.
Prepare & details
Analyze why map keys are essential for understanding a map.
Facilitation Tip: During Symbol Scavenger Hunt: Local Maps, provide highlighters and colored pencils to help students visually group symbols by category.
Setup: Tables with large paper, or wall space
Materials: Concept cards or sticky notes, Large paper, Markers, Example concept map
Design Challenge: Custom Symbols
Small groups brainstorm features missing from a standard key, like electric car chargers, then draw and label three new symbols. Groups present to the class for a vote on clarity and test symbols on a blank map.
Prepare & details
Design new symbols for features not typically found on a map key.
Facilitation Tip: For Design Challenge: Custom Symbols, circulate with a checklist to ensure each student explains their symbol’s purpose to at least one peer.
Setup: Tables with large paper, or wall space
Materials: Concept cards or sticky notes, Large paper, Markers, Example concept map
Map Relay: Key Decoding
Divide the class into teams. Each player runs to a station map, reads a key symbol to name the feature aloud, then tags the next teammate. First team to finish wins; debrief on tricky symbols.
Prepare & details
Evaluate how different symbols can represent the same feature on various maps.
Facilitation Tip: Set a 3-minute timer during Map Relay: Key Decoding so teams must review the key quickly, mirroring real-world map-reading urgency.
Setup: Tables with large paper, or wall space
Materials: Concept cards or sticky notes, Large paper, Markers, Example concept map
Compare and Contrast: Symbol Sets
Whole class views two maps of Ireland side-by-side on the board. Students call out matching and differing symbols for features like mountains, then vote on preferred designs in a quick poll.
Prepare & details
Analyze why map keys are essential for understanding a map.
Facilitation Tip: For Compare and Contrast: Symbol Sets, assign each group one symbol to trace across maps, then present findings to the class.
Setup: Tables with large paper, or wall space
Materials: Concept cards or sticky notes, Large paper, Markers, Example concept map
Teaching This Topic
Start with familiar places to build confidence, then introduce unfamiliar symbols to stretch thinking. Use real maps first, then move to simplified versions to focus on key use. Avoid assuming students see symbols as conventions; let them discover inconsistencies through hands-on tasks. Research shows students learn best when they create symbols first and then test them against a key, so design activities in that order.
What to Expect
Students will confidently explain how symbols represent features, create clear symbols for new features, and use keys to decode multiple maps. They will also recognize why consistency in keys prevents confusion and plan simple routes using map keys.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring Symbol Scavenger Hunt: Local Maps, watch for students who draw literal pictures instead of simplified shapes.
What to Teach Instead
Have them compare their sketches to the actual key, then redraw using the key’s style. Ask: 'Which version is easier to recognize at a glance?'
Common MisconceptionDuring Compare and Contrast: Symbol Sets, watch for students who assume all maps use the same symbols for the same features.
What to Teach Instead
Ask them to find one feature that uses different symbols on each map. Then, prompt them to explain why the differences exist, using the key as evidence.
Common MisconceptionDuring Map Relay: Key Decoding, watch for students who guess symbols without checking the key.
What to Teach Instead
Pause the relay and ask the team to point to the key before confirming their answer. Discuss how guessing leads to errors when symbols rely on agreed conventions.
Assessment Ideas
After Symbol Scavenger Hunt: Local Maps, ask students to write a short reflection: 'Choose one symbol you found. Explain why the key’s version is clearer than a literal drawing.'
During Compare and Contrast: Symbol Sets, display two maps side by side. Ask students to identify one feature with different symbols and explain how the key helps them decode each version.
After Design Challenge: Custom Symbols, pose the prompt: 'Your classmate designed a symbol for a library, but you think it looks like a bookstore. How would you improve the symbol so it’s unmistakable? Discuss with a partner and share your ideas.'
Extensions & Scaffolding
- Challenge students to design a symbol set for a fantasy town, then trade with another group to decode it using only the key.
- For students who struggle, provide a partially completed key with common symbols already matched to features.
- Deeper exploration: Ask students to research how symbols differ between Ordnance Survey maps and road atlases, then present their findings to the class.
Key Vocabulary
| Map Key | A legend on a map that explains the meaning of the symbols used. It helps users understand what different shapes, colors, and icons represent. |
| Symbol | A small picture or icon on a map that stands for a real-world object or feature, such as a tree, building, or road. |
| Cartography | The science or practice of drawing maps. It involves creating maps that are both accurate and easy to understand. |
| Legend | Another term for a map key, providing a guide to the symbols and colors used on the map. |
| Feature | A distinctive attribute or aspect of something, such as a mountain, river, or city, that can be represented on a map. |
