Abstract
Design Research (DR) has been used to develop means of supporting mathematical learning for typically-developing students. This study investigated the use of DR to develop context specific tools to support adults with intellectual disabilities (ID) to improve their numeracy capabilities and engagement in daily tasks. Using observation and interview data, findings demonstrated increased engagement and participation in the numeracy demands of these tasks. Participants reported positive perceptions of improving competence and increases in independence. This study demonstrates the application of DR to the field of numeracy and adults with ID and the usefulness of context specific designed tools to support numeracy learning and independence.
