Famous Explorers and Their RoutesActivities & Teaching Strategies
Maps are living documents that evolve as human knowledge grows, and this topic asks students to trace that growth through active engagement. By handling real historical maps and retracing explorers’ routes, students move beyond memorization to see cartography as a dynamic conversation across centuries.
Learning Objectives
- 1Map the significant routes taken by prominent global explorers such as Columbus, Magellan, and Cook.
- 2Analyze the geographical impact of these voyages on global understanding and cartography.
- 3Critique the term 'discovery' in the context of lands already inhabited by indigenous peoples.
- 4Compare the accuracy and content of historical maps from the Age of Exploration with modern maps.
- 5Explain the challenges faced by early explorers in navigation and map making.

Gallery Walk: Maps Through Time
Display a series of maps from the 1400s to today. Students use a checklist to find 'errors' in the old maps (like California being an island) and discuss why the map-makers thought those things were true.
Prepare & details
Map the significant routes taken by prominent global explorers.
Facilitation Tip: During the Gallery Walk, place a labeled globe and flashlight at each station so students can physically model how ancient observers reasoned the Earth was round.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Inquiry Circle: The Mystery Continent
Give groups an outline of a 'new' landmass. They must 'explore' it by asking the teacher specific questions (e.g., 'Is there a mountain here?') and then draw their map based only on the answers they receive.
Prepare & details
Analyze the geographical impact of these voyages on global understanding.
Facilitation Tip: For the Mystery Continent task, give pairs only the portion of a 15th-century map showing the ‘unknown land’—this forces them to infer based on limited clues.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Think-Pair-Share: Here Be Dragons
Show students illustrations of sea monsters on old maps. In pairs, they discuss why cartographers drew these (fear of the unknown, warning of dangers) and what 'monsters' or warnings we might put on a map of space today.
Prepare & details
Critique the term 'discovery' when lands were already inhabited.
Facilitation Tip: In the Think-Pair-Share, hand out a torn photocopy of a medieval map with ‘Here Be Dragons’ written on the edge so students must reconstruct the message before discussing its meaning.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
Teachers often start with a globe and a flashlight to demonstrate lunar eclipses as evidence for a spherical Earth; this concrete proof undercuts the flat-earth myth before any map work begins. Avoid presenting medieval maps as ‘wrong’—instead, frame them as reasonable attempts given the information available. Research shows that students grasp cartographic distortion best when they compare projections side by side, so plan a two-minute transition between Mercator and Gall-Peters to highlight the choices mapmakers make.
What to Expect
Success looks like students confidently explaining how maps reflect both technical advances and cultural assumptions, using explorer routes to justify their claims. They should also recognize that ‘discovery’ is a loaded term when indigenous perspectives are included.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Gallery Walk activity, watch for students who claim medieval Europeans thought the world was flat.
What to Teach Instead
Set up a station with a globe and flashlight; invite students to shine the light and observe the curved shadow on a wall to model how ancient astronomers inferred the Earth’s shape.
Common MisconceptionDuring the Collaborative Investigation activity, watch for students who assume all maps aim for perfect accuracy.
What to Teach Instead
Provide both Mercator and Gall-Peters projections side by side; ask students to measure Greenland on each and note why its size changes, highlighting that map choice involves perspective.
Assessment Ideas
After the Gallery Walk, give students a blank world map and ask them to draw the route of one explorer, label key locations, and write one sentence explaining why that route mattered.
During the Think-Pair-Share, pose the question: ‘Was it fair to call these lands discoveries when people already lived there?’ Listen for students who reference specific encounters (e.g., Cook’s interactions with Aboriginal Australians) to assess their grasp of indigenous perspectives.
After the Mystery Continent activity, show students two maps—one from the Age of Exploration and a modern map—then ask them to identify three differences in geographical representation or detail in writing.
Extensions & Scaffolding
- Challenge: Ask students to redraw Cook’s route on a polar projection map, noting how the shape of the Pacific changes.
- Scaffolding: Provide a word bank of key terms (latitude, longitude, cartographer) on index cards for the Gallery Walk notes.
- Deeper Exploration: Invite students to research a cartographer like Gerardus Mercator and present how their worldview shaped the map’s design.
Key Vocabulary
| Cartography | The art and science of map making. Early cartography involved significant guesswork and limited geographical knowledge. |
| Age of Exploration | A period from the early 15th to the early 17th century when Europeans actively explored the globe by sea, seeking new trade routes and territories. |
| Indigenous Peoples | The original inhabitants of a land, who were present before the arrival of explorers and colonizers. |
| Navigation | The process of planning and directing the course of a ship or aircraft, often using tools like compasses and astrolabes. |
