The Development and Use of Representations in Teaching and Learning about Problem Solving: Exploring the Rule of 3 in Elementary School Mathematics TIMOTHY BOERST 

Contexts of my teaching & scholarship Examine the wide variety of contexts that shaped this scholarship. Collaborative Action Research Context Take a long or short tour of the process I used to study the Rule of 3.



This website is about a mathematical idea,"the Rule of 3," and the myriad of teaching and learning considerations, actions, and reflections that grew out of serious attention to it. The idea is that work on any mathematical topic can beneficially incorporate the use of numerical, algebraic, and geometric/graphic representations. The teaching and learning implications of this idea are numerous and wide reaching.
While my exploration of these questions is ongoing, the examples, reflections, and links available on this website provide an entry point for seeing, describing, and analyzing the role of representations as conduits of meaning making and communication, not as discrete topics or skills. This website also attempts to thickly portray the complex array of thought and action that are involved in transforming a mathematical idea into routine classroom practice. View a PowerPoint file (presented at the NCTM Annual Conference) that provides a streamlined overview of the main elements of my Rule of 3 work.
