This article introduces a task designed around SMP 7: Look for and make use of structure, and it encourages students to explore structure through multiple representations. Each month, elementary school teachers are presented with a problem along with suggested instructional notes and asked to use the problem in their own classrooms and report solutions, strategies, reflections, and misconceptions to the journal audience.
