Introduction

Several studies have identified a general link between pupils’ working memory skills and their mathematical ability.  The researchers defined working memory as the system within the brain that is responsible for manipulating and storing information for brief periods of time. 
This study aimed to find out how specific aspects of working memory contributed to pupils’ mathematical skills at Key Stage 2. 

The study involved 148 pupils from three primary schools in the North East of England who participated in two testing sessions.  Their working memory skills were assessed in the first session and their mathematical abilities were assessed in the second.

The researchers found that the pupils’ working memory skills predicted over a quarter of the differences in children’s scores on a mathematics test, and that pupils’ mathematical abilities, independent of their age, were related to their ability to
• process information; and
• store and manipulate visual information.

The researchers also found that:
• pupils in Year 3 were more reliant on their ability to manipulate and store visual information to solve mathematical problems; and
• pupils in Year 5 were beginning to rely on their ability to manipulate and store verbal information to solve simple mathematical problems.
