Computational thinking can be defined as "solving problems, designing systems, and understanding human behaviour, by drawing on the concepts fundamental to computer science" (Wing, 2006, p. 33). There are strong links between computational thinking associated with coding and mathematical thinking (Wing, 2006). The digital technologies curriculum promotes children's use of "computational thinking and information systems to define, design and implement digital solutions" (Australian Curriculum, Assessment and Reporting Authority [ACARA], 2018a, np). This article is an analysis of a learning activity that was completed as part of a larger research project conducted in two Brisbane primary schools. In this article, the authors describe a learning activity in which seven classes of Year 2 students investigated and subsequently developed coding sequences (of varying complexity) in order to solve simple spatial problems using Beebots.
