🌺 Culturally Grounded
Lessons draw from ʻike kupuna, voyaging, mālama ʻāina, mālama wai, loʻi, coastal stewardship, and Pacific knowledge systems.
📐 Mathematically Rigorous
Culture is not an add-on. Each resource is designed to support meaningful standards-aligned mathematical learning.
📖 Free & Open
Teachers, students, and families can access web lessons, textbooks, worksheets, games, and PDFs without cost.
The Ahupuaʻa Framework
Explore Math Across Uka, Kula, and Kai
The site is organized around a living continuum of place. Teachers can browse by grade level, mathematical topic, or cultural and ecological context.
Uka — Upland
Forests, headwaters, watersheds, rainfall, stream flow, slope, mapping, and environmental observation.
- Mālama wai and stream flow
- Rainfall data and statistics
- Topography, slope, and mapping
Kula — Plains & Loʻi
Agricultural lands, loʻi kalo, food systems, community practice, area, perimeter, fractions, and proportional reasoning.
- Loʻi addition and subtraction
- Fractions in harvest sharing
- Area and perimeter of cultivated spaces
Kai — Shore & Ocean
Shoreline stewardship, waʻa, voyaging, star compass geometry, waves, currents, vectors, and trigonometry.
- Skip counting and mālama kai
- Wayfinding and navigation
- Trigonometry across the Pacific
