Map Symbols and KeysActivities & Teaching Strategies
Active learning builds spatial thinking by moving symbols from abstract paper to tangible tasks. Students decode conventions through sorting, designing, and searching, which strengthens memory and confidence when reading real OS maps later.
Learning Objectives
- 1Analyze how specific Ordnance Survey symbols represent geographical features within a given biome.
- 2Explain the function of a map key in accurately interpreting the spatial distribution of ecosystems.
- 3Design a set of conventional symbols and a corresponding key for a fictional biome map.
- 4Compare the representation of natural and man-made features using different map symbol sets.

Card Sort: Symbol Matching Challenge
Prepare cards with OS symbols on one set and photos or descriptions of features on another. In pairs, students sort and match them, then justify choices using a provided key. Discuss as a class to reveal patterns in symbol design.
Prepare & details
Analyze how map symbols convey information about a landscape.
Facilitation Tip: During the Card Sort, circulate and ask students to justify their matches aloud to uncover hidden misunderstandings about symbol shapes.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Scavenger Hunt: Classroom Map Quest
Create a large classroom map with hidden OS symbols. Small groups use keys to identify features and record locations on worksheets. Groups share findings, voting on the most accurate interpretations.
Prepare & details
Explain the importance of a map key for accurate interpretation.
Facilitation Tip: For the Scavenger Hunt, provide clipboards and colored pencils so students record both symbols and their locations for later discussion.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Design Lab: Custom Biome Symbols
Provide images of a biome like tundra. Small groups invent and draw symbols for key features, then create a key and test it on peers. Refine based on feedback for clarity.
Prepare & details
Design a set of symbols for a specific type of map.
Facilitation Tip: In the Design Lab, limit students to five minutes of sketching before they swap papers with peers for immediate feedback on clarity.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Field Sketch: School Grounds Key
Students walk the school grounds, sketch a simple map, and assign OS-style symbols to features. Back in class, they compile a shared key and compare maps for consistency.
Prepare & details
Analyze how map symbols convey information about a landscape.
Facilitation Tip: For the Field Sketch, model how to measure distances with footsteps so students connect symbols to real space.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Teaching This Topic
Teachers should emphasize that symbols are a shared language, not artistic choices. Avoid letting students rely on guesswork by modeling how to use the key methodically. Research shows that correcting misconceptions early through concrete tasks prevents persistent errors in fieldwork and exam questions.
What to Expect
Students will match symbols to features quickly, explain why keys matter, and create clear symbols with accurate keys. They should use standardized language and critique designs with peers to improve precision.
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 Card Sort: Symbol Matching Challenge, watch for students who match symbols to photos because they believe symbols should resemble features exactly.
What to Teach Instead
Have these students cover the photo and focus only on the simplified OS symbols first. Ask them to explain how each symbol’s shape relates to the feature’s real-world role, not its appearance.
Common MisconceptionDuring Scavenger Hunt: Classroom Map Quest, watch for students who guess symbols based on color or size rather than checking the key.
What to Teach Instead
Require students to write the symbol’s code next to each feature on their hunt sheet, then verify each match with a partner before moving on.
Common MisconceptionDuring Design Lab: Custom Biome Symbols, watch for students who create overly detailed symbols that cannot be quickly recognized by others.
What to Teach Instead
Model simplification by drawing a first draft with too much detail, then a second draft with only essential lines. Ask students which version is easier to remember and why.
Assessment Ideas
After Card Sort: Symbol Matching Challenge, provide a new OS map section with three symbols missing from their sorted sets. Students must identify and label the missing symbols using the provided key.
During Design Lab: Custom Biome Symbols, collect students’ final symbol designs and keys. Assess whether symbols are clear, original, and accompanied by concise explanations that could guide another student to interpret the map.
After Scavenger Hunt: Classroom Map Quest, facilitate a debrief where students explain how the key prevented errors during the hunt. Ask them to give examples of symbols they initially misread and how the key corrected their understanding.
Extensions & Scaffolding
- Challenge: Provide a section of a UK OS map with missing keys. Students infer missing symbols and draft a key for the blank areas.
- Scaffolding: Give students a partially completed key with symbols and definitions mixed up. They must rearrange them correctly before starting the Card Sort.
- Deeper exploration: Compare two OS maps of the same area from different editions. Students identify changes in symbols over time and explain reasons behind updates.
Key Vocabulary
| Conventional Signs | Standardized symbols used on maps to represent specific features, such as buildings, roads, or water bodies. These signs are agreed upon for consistent interpretation. |
| Map Key | A legend on a map that explains the meaning of the symbols used. It is crucial for understanding what each symbol represents on the map. |
| Ordnance Survey Symbols | A specific set of conventional signs used on maps produced by the Ordnance Survey, the national mapping agency of Great Britain. These are widely used for UK geographical contexts. |
| Topographical Map | A map that shows detailed and accurate representations of natural and man-made features, often including contour lines to show elevation. |
