| Abstract | Supporting students to develop an understanding of the meaning of fractions is an important goal of elementary school mathematics. This involves developing partitioning strategies, creating representations, naming fractional quantities, and using symbolic notation. This article describes how teachers can use a formative assessment problem to elicit and understand students' ideas about the meaning of fractions. The fraction problem described in this article was designed using research on children's thinking in elementary mathematics, and it enables teachers to uncover students' understanding of the following essential aspects of understanding the meaning of fractions: (1) partitioning strategies; (2) representations; and (3) language and notation.
