The use of picturebooks to engage children in developing mathematical proficiency is well documented. However, there is limited evidence as to their use with children in the upper primary years. Therefore, we developed a novel initiative in which we would source picturebooks that contained mathematical topics appropriate to this age cohort and trial them in the classroom. In this paper, we present the findings from the seven teachers who took part. The thematic analysis is aligned with the three core principles of Universal Design for Learning. Results demonstrate that use of picturebooks offer learners multiple means of accessing and engaging with mathematical concepts, multiple means of building conceptual representations of mathematics, and lend themselves to multiple means of action and expression in extending, internalising and showcasing learning.
