Famous Explorers and Their Routes

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.

Activity 01

• Gallery Walk
• 40 min · Small Groups

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.

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.

What to look for

Provide students with a blank world map. Ask them to draw the route of one explorer discussed, label key locations, and write one sentence explaining why that route was significant. Collect these to check mapping skills and recall.

Activity 02

• Inquiry Circle
• 50 min · Small Groups

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.

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.

What to look for

Pose the question: 'Was it fair to call these lands 'discoveries' when people already lived there?' Facilitate a class discussion where students share their perspectives, referencing the indigenous peoples encountered by explorers.

Activity 03

• Think-Pair-Share
• 20 min · Pairs

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.

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.

What to look for

Show students two maps: one from the Age of Exploration and a modern world map. Ask them to identify three differences in geographical representation or detail. This checks their ability to compare and analyze cartographic changes.

A few notes on teaching this unit

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.

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.

Watch Out for These Misconceptions

• During the Gallery Walk activity, watch for students who claim medieval Europeans thought the world was flat.

  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.

• During the Collaborative Investigation activity, watch for students who assume all maps aim for perfect accuracy.

  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.
