It has become increasingly clear that the early use of decomposition for addition is associated with later mathematical achievement. This study examined how younger children execute a base-10 decomposition strategy to solve complex arithmetic (e.g. two-digit addition). 24 addition problems in two modalities (WA: Written Arithmetic; OA: Oral…

Research indicates that the early years are a pivotal time for developing foundational mathematical knowledge, and that early experiences with mathematics have a lasting impact on later numeracy skills and academic achievement. However, the importance of early mathematical thinking and learning is often undervalued or overlooked in early childhood…

In Australia, early childhood education takes a play-based approach to supporting children's engagement with mathematical ideas and numeracy development. To assist preschool teachers' implementation of the outcomes in the national Early Years Learning Framework for Australia, the Northern Territory (NT, Australia) has introduced the NT Preschool…
