Year 3 & 4 Technologies - Digital Systems Unit - Australian Curriculum

This comprehensive 10-lesson HASS Technologies unit is fully aligned to Version 9 of the Australian Curriculum and guides students through exploring how digital and information systems meet the needs of people. Across a full 10-week term, students investigate digital systems, data transmission, collaboration tools and online safety while developing essential digital literacy skills for the modern classroom.

Designed to save you time and maximise student engagement, this ready-to-teach unit includes everything you need to deliver explicit, curriculum-aligned lessons with clarity and confidence.

An alternative WA Curriculum planner (2026+) is also included, making this unit ideal for Western Australian teachers preparing for the new requirements.

What Makes This Unit Stand Out?

✔ Fully Updated to Australian Curriculum Version 9

Every lesson links directly to relevant curriculum outcomes, clearly mapped within the editable unit planner.

✔ 10 Structured, Teacher-Friendly Lessons

Each lesson is broken into five to six clear steps, keeping instruction simple, purposeful and easy to follow, so you can focus on student learning rather than prep.

✔ Editable 100+ Slide PowerPoint

Display-ready and designed for use with interactive TVs or Smartboards, the PowerPoint includes:

• Learning intentions and success criteria
• Guided discussion prompts
• Worksheets
• Visual displays and teaching prompts

Everything is organised lesson-by-lesson for seamless delivery.

✔ Engaging, Cooperative Learning Focus

Created by Mrs Amy123, known for fun and highly engaging lessons, this unit incorporates a wide range of cooperative learning strategies. While many lessons include worksheets, others prioritise discussion, collaboration and hands-on exploration.

✔ Clear Assessment & Grading Support

The included editable grading guide outlines what each grade (A–E) looks like, based on two key assessment activities. It is directly linked to the Achievement Standard for Year 3/4 Technologies, giving you clarity and confidence when assessing student progress.
