Build understanding of integers in financial contexts with this focused lesson sequence, designed to develop students' conceptual understanding through explicit teaching, visual models and guided practice. Students explore how income and expenses are represented using positive and negative numbers, learn to calculate profit, loss and break-even, and develop an understanding of the relationship between financial gains and losses in relation to zero.

Built around the I Do, We Do, You Do model, this lesson sequence guides students from explicit instruction to supported practice and independent application. Through modelled examples, collaborative discussion and structured mathematics tasks, students investigate authentic financial scenarios, represent financial outcomes using integers and number lines, calculate income, expenses, profit and loss, and explain their mathematical reasoning.

What's included in this teacher resource?

• Comprehensive lesson sequence focused on understanding integers in financial contexts
• Clear learning intention and success criteria centred on calculating income, expenses, profit, loss and break-even
• Explicit instruction and modelled examples using number lines to represent financial outcomes
• Guided practice tasks supporting students to calculate income, expenses and financial results
• Activities that develop skills in interpreting profit, loss and break-even situations
• Opportunities for students to explain and justify their reasoning using financial language and number lines
• Built-in check-ins for learning to monitor understanding throughout the lesson
• A formative exit ticket to assess understanding of income, expenses and financial outcomes

Perfect for upper primary classrooms, this lesson sequence develops students' conceptual understanding of integers by connecting mathematics to authentic financial situations. Students build confidence interpreting positive and negative values, calculating financial outcomes and explaining their reasoning using mathematical language and visual models.
