Abstract	Having a deeper understanding of division derived from multiple models is of great importance for teachers and students. For example, students will benefit from a greater understanding of division contexts as they study long division, fractions, and division of fractions. The purpose of this article is to build on teachers' and students' understanding of division, with an emphasis on the partitive and measurement division models. The authors begin by offering a rationale for examining division and then describe the two division models. Next, they discuss preservice teachers' understanding of the division models, and they present strategies for writing quality division story problems. The authors conclude by presenting engaging tasks that can be used with teachers to cultivate their understanding of the two division models. A bibliography is provided. (ERIC).
