Teach AC9TDI8K04 this week?
TeachKoala turns this descriptor into a complete lesson — illustrated slides with teacher notes, a differentiated activity sheet and a quiz — aligned to AC9TDI8K04 specifically, never an invented code. Your first lesson is free.

What Year 7 Technologies students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 7 Technologies standard sentences this code builds towards:
- For each of the 4 prescribed technologies contexts they explain how the features of technologies impact on design decisions, and create designed solutions based on analysis of needs or opportunities.
- By the end of Year 8 students explain how people design, innovate and produce products, services and environments for preferred futures.
- They design and trace algorithms and implement them in a general-purpose programming language.
- Students select appropriate hardware for particular tasks, explain how data is transmitted and secured in networks, and identify cyber security threats.
- Students acquire, interpret and model data with spreadsheets and represent data with integers and binary.
- They select and use a range of digital tools efficiently and responsibly to create, locate and share content; and to plan, collaborate on and manage projects.
The Knowledge and understanding progression either side of AC9TDI8K04
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
