The purpose of this article is to describe a middle school mathematics teacher’s model of his students’ responses to algebraic tasks involving equivalent expressions and the distributive property. The teacher engaged in two model-eliciting activities designed for teachers by creating a library of his students’ work and an accompanying “Ways of Thinking”[WOT] sheet (Doerr & Lesh, 2003). These activities were designed to help reveal the teachers’ models of students’ algebraic thinking and to… Expand
