Maps and Spatial Understanding
Overview
This unit develops students' understanding of maps as tools for representing and understanding the world. Students will explore different types of maps, learn to use coordinates, scale, and compass directions, and understand how maps communicate spatial information. Through hands-on mapping activities, students will develop skills in reading, interpreting, and creating maps.
Key Concept
Systems — Maps are systems of representation that use conventions, symbols, and scale to communicate spatial information.
Related Concepts
- Patterns — The spatial arrangements and distributions that maps reveal about human and physical geography.
- Scale — The relationship between distance on a map and actual distance on the Earth's surface.
- Representation — How maps select, simplify, and symbolise geographic information.
Global Context
Globalization and Sustainability — How do maps help us understand our world? How can maps be used to address global challenges?
Statement of Inquiry
Maps are tools that represent, simplify, and communicate spatial information about our world.
Inquiry Questions
Factual Questions

Content
Week 1: Introduction to Maps
- What is a map? Purpose and types of maps.
- Key elements of a map: title, legend, scale, compass rose, grid.
- History of mapmaking: from ancient to modern.
- Reading and interpreting simple maps.
Week 2: Direction and Location
- Cardinal and intermediate directions.
- Using a compass and compass rose.
- Grid references: alphanumeric grid systems.
- Latitude and longitude: understanding the global grid.
Week 3: Map Scale and Distance
- What is scale? Ratio, bar, and verbal scales.
- Measuring distance on maps.
- Large scale vs. small scale maps.
- Calculating real-world distances from map measurements.
Week 4: Physical and Political Maps
- Physical maps: landforms, elevation, water bodies.
- Political maps: countries, cities, borders.
- Thematic maps: climate, population, resources.
- Comparing information across different map types.
Week 5: Map Projections and Their Effects
- The challenge of representing a sphere on a flat surface.
- Common projections: Mercator, Robinson, Peters.
- How projections distort size, shape, distance, and direction.
- The political implications of map projections.
Week 6: Creating Maps
- Planning and designing a map for a specific purpose.
- Field mapping: surveying a local area.
- Using digital mapping tools.
- Presenting and evaluating student-created maps.
Summative Assessment
Map Creation Project: Students will create an original map of a real or imaginary place that demonstrates understanding of map conventions (title, legend, scale, compass rose, grid). The map must serve a clear purpose and include both physical and human features, with a written explanation of mapping choices.
Map Interpretation Portfolio: Students will compile a portfolio of map analysis exercises demonstrating their ability to read, interpret, and compare different types of maps.
Formative Assessment
- Map element identification exercises.
- Latitude and longitude location activities.
- Scale calculation and distance measurement practice.
- Map projection comparison worksheets.
- Compass direction exercises.
- Quizzes on map terminology and concepts.
Interdisciplinary Connections
- Mathematics: Scale, ratio, and coordinate systems.
- Science: Understanding Earth's shape, rotation, and grid system.
- History: Historical maps and the development of geographic knowledge.
- Design: Map design principles and visual communication.
Service as Action
- Create a map of the school grounds for new students or visitors.
- Develop a neighbourhood map highlighting community resources.
- Participate in a community mapping project for local planning.
- Create accessible maps for community events or organisations.
IB Learner Profile
- Inquirers: Students ask questions about how the world is represented and understood.
- Knowledgeable: Students understand geographic concepts and mapping conventions.
- Thinkers: Students analyse spatial patterns and the strengths of different map types.
- Communicators: Students express spatial information effectively through maps.
- Reflective: Students reflect on how maps shape their understanding of the world.
