Tracking Time Representing Elapsed Time on an Open Timeline
Peer reviewed Peer reviewed

Dixon, Juli K. – Teaching Children Mathematics, 2008
Elapsed-time problems are notoriously difficult for children. Instruction on techniques for teaching and learning elapsed time is not emphasized in current mathematics education literature. Nor is it addressed in "Curriculum Focal Points for Prekindergarten through Grade 8 Mathematics: A Quest for Coherence" (NCTM 2006). This absence of…

Modeling Students' Mathematics Using Steffe's Fraction Schemes
Peer reviewed Peer reviewed
Direct linkDirect link
Norton, Anderson H.; McCloskey, Andrea V. – Teaching Children Mathematics, 2008
Each year, more teachers learn about the successful intervention program known as Math Recovery (USMRC 2008; Wright 2003). The program uses Steffe's whole-number schemes to model, understand, and support children's development of whole-number reasoning. Readers are probably less familiar with Steffe's fraction schemes, which have proven similarly…

Alternative Algorithms: Increasing Options, Reducing Errors.
Peer reviewed Peer reviewed
Randolph, Tamela D.; Sherman, Helene J. – Teaching Children Mathematics, 2001
Presents several alternatives to customary algorithms for whole number arithmetic. Includes a brief history of each algorithm and discusses why each might be useful for particular kinds of children. (KHR)

Responses to the How Many Towers? Problem.
Peer reviewed Peer reviewed
Olson, Melfried; Olson, Judith – Teaching Children Mathematics, 2000
Discusses a problem that appeared in the September, 1999 issue of this journal and presents solutions from students in grades 2-6. The question involved using colored cubes rearranged to make different stacked towers. (KHR)

What Nathan Teaches Us about Transitional Thinking
Peer reviewed Peer reviewed
Direct linkDirect link
Taylor, Ann R.; Breck, Susan E.; Aljets, Carol M. – Teaching Children Mathematics, 2004
This article demonstrates how a child's invented algorithm about tens and ones generated "transitional thinking" on the way to the construction of a mathematical understanding of place value. The articles also discusses how two important "best practice" classroom strategies, mathematical discourse, and the role of wait time in that discourse take…
