Investigating the Improvement of Prospective Elementary Teachers’ Number Sense in Reasoning about Fraction Magnitude
This study explored whether and how prospective teachers (PTs) fraction sense could improve in the setting of a Number and Operations course. the results from the interviews with seven participants provide evidence that their performance and flexibility in comparing fractions improved. The authors found that 6 of the 7 interview participants adopted at least two new valid strategies for comparing fractions. Consequently, these findings can guide mathematics teacher educators how to support PTs to reason meaningfully and flexibly about fraction magnitude.

Strategy Ranges: Describing Change in Prospective Elementary Teachers’ Approaches to Mental Computation of Sums and Differences
This article 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.
