The Billion-dollar Flush by Wayne Erb is an engaging non-fiction text that takes students deep beneath Auckland to explore one of New Zealand’s largest and most ambitious infrastructure projects: the Central Interceptor wastewater tunnel. Through clear explanations, diagrams, and real-world voices from engineers, geologists, and environmental advisors, students learn how science, technology, and engineering work together to solve complex urban and environmental problems.

This text supports students to build strong comprehension of complex informational texts, interpret technical vocabulary, and analyse how authors use structure, diagrams, and real examples to explain sophisticated ideas. The text also encourages critical thinking about sustainability, population growth, and human impact on waterways, helping students connect learning to real issues in Aotearoa New Zealand. This text is ideal for inquiry learning, STEM integration, and discussions about future-focused solutions for growing cities.

 

This Interactive Comprehension Check has been carefully designed to consolidate and deepen students’ understanding of Standing with the Ancestors.

Rather than simply revisiting surface details, the questions intentionally target inference, author purpose, vocabulary in context, and deeper thinking. This resource supports meaningful retrieval practice while maintaining academic rigour and clarity.

The Check can be used:

• As an end-of-text consolidation activity
• As revision prior to assessment
• As a retrieval task in subsequent weeks
• As an engaging formative check for understanding

Each question aligns with key literacy skills, supporting students to think critically, justify ideas, and revisit important language and themes.

 

This pack includes:

• Private access link to the interactive quiz
• Lesson overview slides with learning intention and success criteria
• Reflection / extension task to deepen thinking

This resource is designed to support purposeful teaching, structured discussion, and confident assessment — while reducing preparation time.
