Teacher-only planning companion for Unit 10 Week 2 Rua Kūmara Volume Calculation. Use this page to keep the numeracy work tied to storage capacity, planning, and scarcity.
This is strongest when students move beyond the formula to answer the real question: what does this amount of storage allow people to do across time?
MATHEMATICS-8cb7e35600: Communicating findings in context to answer an investigative question, using evidence, providing explanations, and evaluating whether claims are supported by the data.
The task asks students to calculate or estimate capacity and then explain what that result means for storage and food security.
Useful when you want the calculation explained rather than left as a raw number.
TM-SS-3-K1: How different systems function in Aotearoa and globally — storage capacity is one measurable part of a wider food system shaped by climate, labour, timing, and community need.
The numerical answer becomes meaningful when students connect capacity to protecting harvests and planning for future scarcity.
This keeps the numeracy work inside the Unit 10 inquiry.
Context matters. Volume questions become far more powerful when students understand what is being stored, why it mattered, and how design choices protected kai over time.
Always finish with a “so what?” question about winter, spoilage, and planning. That is where the concept of scarcity returns.
Best used after the rua analysis sheet, not before it.
