Abstract:

The paper presents part of a research study that intended to use the history of mathematics for the development of place value concepts and the notion of carried number with sixth grade Greek students. In the given pre-tests students faced difficulties in solving place value tasks, such as regrouping quantities and multi-digit subtractions. Also, they vaguely explained the carried number, a notion which is structurally associated with calculations. We held an instructive intervention via a historical calculating tool, the Chinese abacus. In the post-tests students improved their scores and they often put forward expressions influenced by the abacus investigation. To a smaller extent we attempted to highlight the historical dimension of the subject.
