Year 3 & 4 Technologies - Algorithm Unit - Australian Curriculum

This comprehensive 10-lesson Digital Technologies unit, updated to Australian Curriculum Version 9, explicitly teaches students how to define problems, develop algorithms and evaluate how solutions meet design criteria and user stories. Across a full 10-week term, students build foundational computational thinking skills as they explore sequencing, branching, iteration and simple visual programming in an engaging, structured way.

If you are looking for a curriculum-aligned Year 3/4 Digital Technologies unit on algorithms and problem-solving that is low-prep, high-impact and classroom-ready, this is it.

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

Why Teachers Love This Unit

✔ Fully Updated to Australian Curriculum Version 9

Every lesson is clearly mapped to the relevant curriculum outcomes, making planning, documentation and reporting simple.

✔ Complete 10-Week Term Plan

Ten carefully sequenced lessons guide students step-by-step through:

• Defining problems using design criteria
• Co-creating user stories
• Developing and implementing simple algorithms
• Exploring control structures including sequencing, branching and iteration
• Evaluating how solutions meet intended needs

✔ Editable 100+ Slide PowerPoint

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

• Learning intentions and success criteria
• Explicit teaching slides
• Key discussion prompts
• Worksheets
• Visual resources

✔ Time-Saving, Clear Lesson Structure

Each lesson follows five to six concise steps with clear instructions and highlighted teaching points, so you can focus on student engagement rather than preparation.

✔ Engaging & Collaborative Learning

Created by MrsAmy123, known for highly engaging and cooperative classroom strategies, this unit balances worksheets with hands-on, discussion-based and collaborative activities to deepen understanding.

✔ Clear Assessment 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 confidence and clarity when assessing student achievement.

🎯 Full Curriculum Alignment (Version 9)

Define problems with given design criteria and by co-creating user stories (AC9TDI4P01)

Implement simple algorithms as visual programs involving control structures and input (AC9TDI4P04)

Discuss how existing and student solutions satisfy the design criteria and user stories (AC9TDI4P05)

Follow and describe algorithms involving sequences, comparison operators (branching) and iteration (AC9TDI4P02)

🎯 WA Curriculum Outcome

Year 3

Represent algorithms (sequence of steps), including decisions made by the user (branching) using flow charts (WA3DIGDI1)

Implement algorithms (sequence of steps) in a visual programming environment to include decisions made by the user (branching) (WA3DIGDI2)

Data is of different types and can be represented in various ways (WA3DIGDR1)

Year 4

Data of the same type can be represented in different ways depending on the purpose (WA4DIGDR1)

Represent an algorithm (sequence of steps) involving decisions (branching) and repetition using flow charts (WA4DIGDI1)

Implement algorithms (sequence of steps) in a visual programming environment to include decisions (branching) and repetition (WA4DIGDI2)

Use given criteria to evaluate design features, selected resources, decision-making processes and the designed solution (WA4DIGDTEV1)
