The North Carolina Standard Course of Study 2003 mathematics standards call for third-grade students to develop fluency in solving problems that involve multiplication and division. Released test items from the statewide standards-based assessment include multiplication and division tasks that require students to read the problem, identify the correct operation, and correctly calculate their solution. These authors strive to make mathematics instruction problem oriented, requiring that students read the task, choose among the four operations on the basis of the task's context, and then accurately compute a solution. In this article, they describe a lesson where students wrote story problems for the division task 10 divided by 5 and what they, as educators, learned from the experience. (Contains 3 figures.)
