| Abstract | This article describes how to multiply binomials so that middle school students produce the equivalence (a + b)[superscript 2] = a[superscript 2] + 2ab + b[superscript 2] after reasoning about and representing problems. First, a two-dimensional array representation is used so that students can become comfortable with multiplication embedded in their figures. Later, an area model is used. Such area models provide multiple representations of squaring a binomial; in so doing, these diagrams give students multiple ways to understand the concept. (Contains 7 figures.) (ERIC). |
