Abstract
Patterning and spatial skills are central to mathematics achievement and are precursors to generalising in mathematics. This paper draws together three complementary lines of research on the role of pattern and structure, number sense, and STEM in early learning to consider the interrelations between patterning and spatial skills, and their influence on mathematical achievement. An overview of the ‘Pattern and Structure’ project, studies on patterning and number sense, and the Early Years STEM Australia (ELSA) project highlight commonalities in approaches and findings. An integrated approach aims to develop an improved understanding on how and why patterning, spatial skills and number sense are linked and are ‘transferred’ to mathematical achievement.
