🧭 Master Navigators
Polynesian navigators crossed the Pacific Ocean — the world's largest body of water — using only the stars, waves, winds, and their knowledge passed down through generations.
They didn't have GPS, compasses, or maps. Instead, they memorized the positions of hundreds of stars and understood how the sky changes throughout the year. This is coordinate mathematics in action!
⭐ Key Stars for Pacific Navigation
Māhutonga
Southern Cross
Points to the South Pole
Matariki
Pleiades cluster
Marks the Māori New Year
Rehua
Antares
Bright red star of summer
Tākurua
Sirius
Brightest star in the sky
📍 Coordinates in the Sky
Astronomers use a coordinate system to locate stars, just like we use coordinates on a map!
- Altitude: How high the star is above the horizon (0° to 90°)
- Azimuth: Direction along the horizon (0° North, 90° East, 180° South, 270° West)
Traditional navigators memorized where important stars would rise and set — their azimuth positions — at different times of year.
📝 Activity 1: Star Map Grid
Plot these stars on the coordinate grid. The first one is done for you.
| Star | Coordinates (across, up) |
|---|---|
| Māhutonga (Southern Cross) | (3, 2) ✓ |
| Matariki | (7, 8) |
| Rehua | (5, 5) |
| Tākurua | (2, 7) |
📝 Activity 2: Navigation Challenge
A navigator is sailing from point A(2, 3) to point B(8, 7).
a) Plot both points on a grid and draw the route.
b) How many units East must they travel?
c) How many units North must they travel?
d) If they sail diagonally, will the distance be more or less than traveling East then North? Explain.
📝 Activity 3: Finding South
Navigators use the Southern Cross to find South. The long axis of the cross points toward the South Celestial Pole.
If Māhutonga rises at azimuth 150° and sets at azimuth 210°, what azimuth is it at when directly South?
Why is knowing the direction of South useful for navigation?

Aronga Mātauranga Māori
This resource sits within a kaupapa that recognises mātauranga Māori as a living knowledge system with its own frameworks, values, and ways of understanding the world. The New Zealand Curriculum calls for learning that reflects the bicultural partnership of Te Tiriti o Waitangi, which means every subject area has an obligation to engage authentically with Māori perspectives — not as cultural decoration but as substantive contributions to how we understand our topics. The concepts of manaakitanga (care for others), kaitiakitanga (guardianship), whanaungatanga (relationship and belonging), and tino rangatiratanga (self-determination) provide a values framework applicable across all learning areas, and all are relevant to the work in this handout.

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to build understanding of Aotearoa New Zealand's ecosystems, biodiversity, and the role of kaitiakitanga in environmental stewardship.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain key concepts from this resource using their own words.
- ✅ Students can connect the content to real-world environmental contexts in Aotearoa.
Differentiation & Inclusion
Scaffold support: Provide sentence starters, word banks, or graphic organisers to scaffold access for students who need it. Offer entry-level and extension tasks to address a range of readiness levels.
ELL / ESOL: Pre-teach key vocabulary and provide bilingual glossaries where available. Allow students to respond in their home language first.
Inclusion: Use accessible formats — clear font, adequate whitespace, structured tasks. Neurodiverse learners benefit from chunked instructions and choice in how they demonstrate understanding.
Prior knowledge: Best used after the relevant lesson sequence. No specialist prior knowledge required for entry-level engagement.
