Overview

This 60-minute lesson is the second in a 10-lesson unit called "Understanding Government Finance" for Year 10 Business students in New Zealand. It focuses on understanding different types of taxes, specifically income tax and Goods and Services Tax (GST), and their role in raising revenue for the government.

The lesson is designed strictly in alignment with the New Zealand Curriculum Refresh (Te Mātaiaho) and builds key competencies alongside business knowledge, applying social sciences and financial mathematics concepts.

Learning Objectives

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

• Explain the purpose of taxation and its importance in government finance within New Zealand.
• Identify and describe key types of taxes including income tax and GST.
• Calculate basic GST on given dollar amounts, connecting to financial mathematics.
• Understand the significance of taxes in funding public services and infrastructure.
• Develop responsible attitudes towards civic participation aligned with the Key Competency of Participating and Contributing (NZ Curriculum).

NZ Curriculum Links:

• Social Sciences Learning Area (understanding economic activities and government roles).
• Financial Mathematics Content – calculating GST and understanding percentages (Te Mātaiaho Mathematics and Statistics, Year 9-10) .
• Key Competencies: Participating and Contributing, Thinking, Using Language, Symbols, and Texts .

Lesson Structure

Time	Activity	Description	Resources	Purpose
0-5 min	Introduction & Context Setting	Briefly revisit the previous lesson on government finance introduction. Introduce today's focus on taxes as a key revenue source.	Whiteboard, projector	Activate prior knowledge and orientation to lesson topic
5-15 min	Interactive Presentation: Types of Taxes	Use a digital presentation to explain:

• What taxes are
• Income tax: how individuals pay based on earnings
• GST: what it is and how it applies to goods/services in NZ
  Include examples relevant to NZ teens (e.g., part-time job income tax, buying lunch) | Slide deck with visuals, NZ tax system examples | Build foundational knowledge of NZ tax types relevant to students | | 15-25 min | Group Activity: Tax Types Sorting | Students in groups of 5 sort cards showing different taxes (e.g., income tax, GST, property tax, excise duty) into categories: Direct or Indirect tax, Mandatory or Voluntary (discussion supported by teacher). | Tax cards (printed), worksheet | Encourage collaborative learning and deeper tax category understanding | | 25-35 min | Calculation Practice: GST and Income Tax | Teacher-led modelling of calculating 15% GST on given prices (e.g., $20 lunch, $432 concert ticket). Students then solve 3-4 similar problems on own or in pairs. Discuss with rounding practices and money format (NZD). | Worksheets, calculators | Develop financial mathematics skills aligned with NZ Curriculum | | 35-45 min | Class Discussion: Why Tax? | Guided whole-class discussion on why governments need taxes, using NZ examples (healthcare, education, roads). Link this back to the role of taxes in democracy and society. | Whiteboard, discussion prompts | To deepen understanding of taxation's societal significance and reinforce key competencies (Thinking, Participating and Contributing) | | 45-55 min | Scenario Role-Play | Students role-play as different stakeholders — e.g., government official, taxpayer (student with part-time job), business owner. They debate tax purpose, usage, and fairness. Teacher prompts with questions to stimulate critical thinking. | Role cards, timer | Engage students in applying knowledge and appreciating different perspectives | | 55-60 min | Reflection & Exit Ticket | Students write one new thing they learned about taxes and one question they still have, to hand in as exit ticket. Quick verbal sharing optionally. | Exit ticket slips or digital form | Assess understanding and inform future lessons |

Assessment and Feedback

• Formative: Observation during group sorting and role-play, discussion participation.
• Summative: GST calculation worksheet accuracy.
• Exit ticket provides individual reflection data for teacher follow-up.

Differentiation & Inclusion

• Provide calculators or digital tools for students who need them during calculations.
• Use clear, accessible language and visual aids to explain tax concepts.
• Support ELL learners with vocabulary sheets including terms like GST, income tax, revenue.
• Incorporate Māori concepts where possible, discussing taxation's role in supporting societal wellbeing, aligning with Te Tiriti o Waitangi commitments and the Principle of inclusion .

---

Teacher Notes

• Emphasise New Zealand’s current GST rate (15%) for calculation relevance.
• Link tax types and calculations back to everyday scenarios familiar to students for engagement.
• Maximise use of discussion and reflection to build key competencies particularly Thinking, Participating and Contributing, and Using Language, Symbols, and Texts.
• Encourage respect for diverse perspectives during role-play to model citizenship behaviours.
