Direct instruction

15 min

Show double-hulled canoe model. Walk through 5 features: TWO HULLS, CONNECTING DECK, SAIL (often crab-claw shape), STEERING PADDLE, WAYFINDING CREW. Explain breadfruit and taro: staple food plants carried by voyagers, planted at each landfall. Show MG-9 Polynesian network with breadfruit/taro spread shown. Read aloud Patricia Grace or Witi Ihimaera excerpt. CRITICAL FRAMING: refuse 'accidental drift' theory. Polynesian voyaging was INTENTIONAL, two-way, sophisticated.

Key examples
  • Notice: the design solves the specific problem of long ocean voyages. Different problem = different design.
    model Two hulls give stability against waves. Cargo and crew can be distributed between the hulls. The space between the hulls allows passengers and supplies. The design lets the canoe carry food-plants like breadfruit and taro across thousands of miles of ocean.
    prompt Why is a double-hulled canoe better for long ocean voyages than a single-hulled boat?
Checks for understanding
  • What is a double-hulled canoe? Name TWO food plants Polynesian voyagers carried.
Sourcework

Children examine the double-hulled canoe model as an artifact. Apply the 6-question Artifact-Reading Card. Focus on Box 3 (USE - long ocean voyaging) and Box 4 (MAKER - Polynesian shipwrights and wayfinder crews). They examine breadfruit/taro photographs as primary-source evidence of agricultural diffusion.

Guided practice

15 min
Tasks
  • Sketch the double-hulled canoe with 5 labeled features (two hulls, deck, sail, steering paddle, wayfinding crew area).
    scaffold Picture support and sentence frame
  • Trace breadfruit's diffusion path across the Pacific from West Polynesia outward (Marquesas, Hawaii, Aotearoa, Rapa Nui) using MG-9.
    scaffold Teacher checks each pair

Formative assessment

3 min
Exit ticket
  • Name TWO features of a double-hulled canoe.
  • True or false: Polynesian settlement was accidental drift.
scoring Full sentences with required elements = mastery; partial = practicing; missing key element = reteach

Closure

Moves
  • Restate: 'Polynesian voyaging was intentional, two-way, and used sophisticated navigation'
  • Preview lesson 15's trade networks and cultural diffusion

Homework

Teacher notes

Lesson 14 closes the Polynesian two-lesson arc. The intentional-voyaging refusal of accidental-drift refutes Thor Heyerdahl's mid-20th-century theory. The breadfruit-taro diffusion ties to lesson 15's broader cultural-diffusion theme.
