Abstract
International research demonstrates that between 6% - 8% of students face very significant and persisting mathematical learning difficulties (MD). It is still little understood why some students experience so much difficulty in mastering basic mathematical concepts and skills. This researcher will argue that verbal memory span weaknesses have been reliably associated with MD and present research with Year 2 Queensland students which confirms this finding. The paper explores how verbal memory weaknesses can constrain early maths learning, and reports an intervention designed to circumvent these restrictions with a low-attaining Year 4 student.
