Abstract
Research has shown that mental computation is a valid computational method which contributes to mathematical thinking as a whole (e.g., Sowder, 1990). This paper reports on a pilot study of young children's understanding of mental computation, and compares the mental architecture of two mental computers, one flexible and one inflexible. Further questions which have been raised as a result of this pilot study will also be discussed
