Direct linkHunt, Jessica; Silva, Juanita – Journal for Research in Mathematics Education, 2020
We investigated the extent to which one elementary school child with working-memory differences made sense of number as a composite unit and advanced her reasoning. Through ongoing and retrospective analysis of eight teaching-experiment sessions, we uncovered four shifts in the child's real-time negotiation of number over time: (a) initial…

Peer reviewedMarkovits, Zvia; Sowder, Judith – Journal for Research in Mathematics Education, 1994
Examined the effects of intervention in the instruction of 12 male seventh-grade students for the purpose of developing number sense. Results indicate that after instruction students were more likely to use strategies to solve number magnitude, mental computation, and computational estimation problems that reflected number sense. (Contains 50…
