Understanding Algorithms & Coding | Digital Technologies | Years 3–4 | Australian Curriculum Aligned

This engaging resource introduces students in Years 3 and 4 to the foundational concepts of algorithms and coding as part of the Australian Curriculum: Digital Technologies. Through a series of accessible, hands-on activities, students will explore how computers and robots follow sets of instructions to solve problems and complete tasks.

Perfect for classroom use, this resource helps demystify coding by breaking it down into clear, step-by-step concepts, and showing how it relates to real-world problem-solving—just like following a recipe or building a LEGO model!

💡 What Students Will Learn:

• What an algorithm is and how it functions
• The role of step-by-step instructions in programming
• That computers follow precise, logical sequences to complete tasks
• Introduction to the idea that coding uses specialised programming languages (e.g., Python, Java, BASIC)
• That coding is just another way of giving instructions – not as complex as it seems!
