Year 3 & 4 Technologies - Data Representations Unit - Australian Curriculum

This comprehensive 10-lesson Digital Technologies unit, fully updated to Australian Curriculum Version 9, supports students to represent, understand and use different types of data, and examine how online accounts work in everyday life. Across a full 10-week term, students build foundational knowledge of digital systems, data representation and online safety while developing essential early computational thinking skills.

If you’re searching for a curriculum-aligned Year 3/4 Digital Technologies unit on digital systems, data and personal information, this ready-to-teach resource delivers clarity, engagement and strong assessment alignment.

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

Why This Unit Stands Out

✔ Complete 10-Week Teaching Sequence

Ten structured lessons guide students to:

• Recognise different types of data
• Explore how the same data can be represented in different ways depending on purpose
• Understand digital systems in everyday contexts
• Identify what personal data is stored and shared in online accounts
• Discuss risks associated with sharing information online

Students develop both conceptual understanding and practical digital awareness in age-appropriate, engaging ways.

✔ Editable 100+ Slide PowerPoint

Designed for use with a Smartboard or classroom TV, the editable PowerPoint includes:

• Learning intentions and success criteria
• Clear teaching slides
• Key discussion prompts
• Worksheets and visual displays

✔ Simple, Time-Saving Lesson Structure

Each lesson follows five to six clear steps, with concise instructions that highlight key teaching points. Less prep for you means more meaningful learning time for your students.

✔ Engaging & Cooperative Learning

Created by MrsAmy123, known for highly engaging lessons and cooperative learning strategies, this unit balances explicit teaching with discussion, collaboration and purposeful worksheet activities.

✔ Clear Assessment & Grading Support

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