ab: Summary: This study investigated the sets of mental computation strategies
used by prospective elementary teachers to compute sums and differences
of whole numbers. In the context of an intervention designed to improve
the number sense of prospective elementary teachers, participants were
interviewed pre/post, and their mental computation strategies were
analyzed. The analysis led to the identification of the strategy ranges
used by the participants, as well as descriptions of changes pre/post
in those strategy ranges. This article illustrates how strategy ranges,
as an analytic tool, afford useful descriptions of the repertoires of
mental computation strategies that individuals use.
