Horopaki · Cultural Context — He aha te hāngī?
A hāngī is a traditional Māori method of cooking kai in an earth oven. Hot stones are placed in a pit, food is wrapped in leaves and baskets, then covered with earth to steam for several hours. Hāngī is central to manaakitanga — the practice of caring for others through generous hospitality.
When food is cooked in a hāngī, it must be shared fairly among all whānau and guests. This is not just a cultural value — it is mathematics in action. Fair sharing is the foundation of fractions.
Rapanga 1 · Problem 1: Sharing Kūmara
Te horopaki · The scenario
Nana has cooked 12 kūmara in the hāngī. She wants to share them equally among 4 whānau (families).
a) How many kūmara does each whānau get? Show your working.
b) Write each whānau's share as a fraction of all 12 kūmara.
Each whānau gets out of 12 kūmara, which we write as .
c) Can you simplify that fraction? What is the simplest form?
d) Draw 12 kūmara below and circle groups to show how they are shared among 4 whānau.
Rapanga 2 · Problem 2: Chicken Portions
Te horopaki · The scenario
The hāngī has 8 pieces of chicken (heihei). There are 16 people to feed.
a) What fraction of one piece of chicken does each person get? Show your reasoning.
b) Four people at the gathering are vegetarian and don't eat chicken. Now how much chicken can each of the remaining people have? Write your answer as a fraction and a decimal.
Rapanga 3 · Problem 3: Hāngī for the Hui
Te horopaki · The scenario
The marae is hosting a large hui with 60 manuhiri (guests). The hāngī team has prepared:
- 30 kūmara
- 45 rīwai (potatoes)
- 20 pieces of chicken
a) What fraction of a kūmara does each guest receive? Simplify your answer.
b) How many potatoes does each guest get? Write this as a fraction and simplify.
c) One-third (⅓) of guests are vegetarian and do not eat chicken. How many guests share the chicken? How much chicken does each of them receive? Show your working.

Challenge: Write two equivalent fractions for the share of kūmara each whānau received in Problem 1.
Whakaaro Hōhonu · Reflection — Manaakitanga and Fractions
Manaakitanga means showing respect, generosity, and care for others — especially through the sharing of kai.
In your own words: how does understanding fractions help us practise manaakitanga? What would happen if the sharing was not equal?
Aronga Mātauranga Māori
Fractions in te ao Māori are not an abstract concept — they are embedded in the practice of manaakitanga. The act of tohatoha (sharing) ensures that every person receives their fair portion, reflecting the values of equality and community. The hāngī is a communal technology that feeds entire hapū and iwi, requiring careful proportional thinking to ensure no one goes hungry. Exploring fractions through this lens honours Indigenous mathematical knowledge and connects numeracy to cultural identity and obligation.
Ngā Rauemi Tautoko · Support Materials

- Equivalent fractions table with student completion spaces
- Manaakitanga reflection question
- Bilingual headings (te reo Māori / English)
Aronga Rerekē · Differentiated Pathways
Entry-level support
Provide physical kūmara models or counters to represent the sharing in Problem 1. Use the fraction wall as a visual anchor before attempting the table. Focus on halves and quarters only. Use the stem: "I shared ___ into ___ equal groups, so each group is ___."
On-level
Complete all three problems independently. Use the fraction wall to verify equivalent fractions. Write explanations using both English and kupu Māori. Tackle all rows of the equivalent fractions table.
Extension / Whakaaro Hohonu
Plan your own hāngī for 24 people: decide how much of each kai is needed so every person receives 1 kūmara, 1½ potatoes, and ⅓ of a chicken. Express all quantities as mixed numbers. Calculate total cost if kūmara cost $2.50 each, potatoes $3/kg, and chickens $15 each.
