Résumé
We investigated the development of two-dimensional space concepts within a mathematics unit on grids, coordinates, and rectangles, part of a large-scale curriculum development project funded by the NSF. Data from case studies, interviews, paper-and-pencil tests, and whole-class observations were collected during field tests with 4 fourth-grade classrooms. Students had to overcome substantial hurdles in learning to spatially structure two-dimensional grids, including interpreting the grid's components as line segments rather than regions; appreciating the precision of location the lines required, rather than treating them as fuzzy boundaries or indicators of intervals; and learning to trace vertical or horizontal lines that were not axes. We found no evidence for a relationship between students' strategies for naming and locating coordinates and their other knowledge of grid and coordinate systems; instead, such knowledge was related to students' levels of competence in three aspects o
