Overview

This 60-minute lesson is designed for Year 4-6 bilingual Māori students to explore and reflect on the basic concepts of money through practical calculations of profit after running a stall. The focus is on understanding money using decimals, adding amounts, and calculating profit. This is culturally responsive and bilingual (English and Te Reo Māori), aligned with the refreshed New Zealand Curriculum (Te Mātaiaho Mathematics and Statistics for Years 4-6).

Learning Outcomes

By the end of this lesson, students will be able to:

1. Use dollars and cents vocabulary in both English and Māori (e.g., “tāra”, “hēneti”) to express money amounts correctly.
2. Add money amounts using decimals to two places (e.g., $4.25 + $2.50 = $6.75).
3. Calculate profit after subtracting costs from income using simple subtraction of decimals.
4. Reflect on their stall’s financial outcome using mathematical language with bilingual support.

Lesson Breakdown

Time	Activity	Description & Resources	Language Support
0-10 mins	Introduction & Warm-up	- Karakia (brief welcome/prayer) to connect culturally - Discuss what profit means in the context of a stall - Vocabulary focus: profit/putanga moni, cost/kōwhiringa utu, income/tāke moni, dollars/tāra, cents/hēneti - Use visual flashcards with English & Māori terms and images of coins & notes	Vocabulary flashcards with bilingual labels, explain terms clearly
10-25 mins	Practical Calculation - Adding Money	- Present students with a simplified sales list from the stall: list of items sold with prices - In pairs, students add amounts of money using play money or amounts written with decimals to two places - Use number lines or decimal place value charts to support addition - Model adding amounts both horizontally and vertically - Use bilingual maths facts: e.g., “E whā tāra tekau mā rima hēneti + e rua tāra whitu tekau hēneti =?”	Model and scaffold both languages; emphasise decimal notation and place value houses
25-40 mins	Calculating Profit	- Recap total income (money received from sales) - Introduce costs (supplies or stall rental) - Students subtract costs from income to find profit: use basic subtraction of decimals to two places - Connect to practical contexts: “If income is $45.50 and costs are $20.75, what is the profit?” - Encourage students to explain reasoning aloud in te reo Māori and English	Use sentence stems: “Ko te putanga moni he...” / “The profit is...” Visual support for decimal subtraction
40-50 mins	Group Reflection Discussion	- Discuss what the students learned about handling money and profit - Ask: “Why is it important to know about profit?” / “He aha te take nui o te mōhio ki te putanga moni?” - Encourage bilingual discussion; write key points in both languages on the board - Invite students to orally share calculations and understanding	Encourage respectful talk and turn-taking using Te Reo Māori greetings and expressions
50-60 mins	Assessment & Wrap-up	- Individually complete a short worksheet: add given prices, subtract a cost, and state profit in English and Māori - Check calculations, listen to bilingual explanations - End with karakia or waiata to reinforce cultural connection and celebrate learning	Provide sentence starters and vocabulary sheet for support

Resources

• Play coins and notes (real or laminated)
• Bilingual money vocabulary flashcards
• Decimal place value charts (PV houses)
• Calculators for checking answers
• Whiteboard and markers
• Worksheet: simple profit problems with bilingual instructions and spaces for calculations
• Vocabulary and sentence starter pocket charts

---

Assessment Ideas

• Observe students during paired and group activities to listen for accurate addition and subtraction with decimals.
• Review individual worksheets for correct calculation of total money sold, costs, and profit.
• Check for use of bilingual vocabulary and clear verbal/math explanations.
• Encourage reflection journals (drawing or writing) for students to express what they learned about money in both Māori and English.

---

Cultural and Language Responsiveness

• Use bilingual teaching explicitly throughout (both oral and written forms).
• Begin and end the lesson with Māori cultural practices (karakia, waiata).
• Incorporate familiar contexts (stall, community event) relevant to student experience to make maths meaningful.
• Encourage student bilingual identity by inviting use of te reo Māori terms and supporting scaffolding for maths language.
