The Mental Computation drawer was written by a team from the Mathematics Teaching and Learning Research Centre of the Australian Catholic University, led by the centre’s Director, Prof. Doug Clarke.

The Mental Computation drawer is an outcome of the extensive program of research and work with schools across Australia carried out by the MTLRC over a number of years by Clarke and his colleagues.

A/Prof. Vince Wright, Dr Ann Downton and Prof. Doug Clarke, were responsible for the conceptual design of the drawer. Vince and Ann wrote most of the material.
