Computational thinking is integrated into the Victorian Curriculum Mathematics V2.0. A useful starting point for students and teachers is to consider algorithms that are already familiar. In this session, we will look at the long division algorithm and use a computational thinking approach to understand how the algorithm works, and what it tells us about numbers and divisibility. This includes answers to the following questions: * Why do we work from left-to-right (instead of right-to-left as in other addition, subtraction and multiplication)? * What does the long division algorithm actually do? * How can we link the long division algorithm to our understanding of divisibility? * What can we learn about algorithms in general from this process?

Key takeaways:
1. A deep understanding of how the long division algorithm works.
2. An approach to analyse and understand mathematical algorithms.
