| Abstract | This article discusses two sequences of activities that were developed to support middle school students' and preservice teachers' construction of algorithms for dividing fractions. One sequence is intended to promote understanding of the common-denominator algorithm; the other sequence is intended to promote understanding of the invert-and-multiply algorithm. The authors discuss the rationale behind the two sequences and relate them to the measurement and fair-sharing interpretations of division. (Contains 7 figures.) (Author). |
