This paper explores the process by which mathematical knowledge is socially constructed. Interactional analysis of a lesson on fact families shows how one third-grade mathematics class negotiated the meanings of writing a number sentence for a picture and a fact family. In the course of classroom interactions, teacher and students shifted the lesson's focus from number sentences that represented physical images to permutations of 3 numerals around 2 operation symbols.
