ab: From the text: Mathematical argumentation is a special kind of discourse,
the goal of which is to determine the truth of mathematical
statements.-Supporting argumentation is complex, and teachers need a
variety of methods for doing so. The method we focus on in this article
is giving students advice about how to behave as they engage in
mathematical argumentation. Although much has been written on
questioning to support mathematical discourse, telling is an important
teaching move, too.
