DescriptionIn the seventh clip in a series of nine from the fourth of seven interviews in which 8th grader Stephanie explores Early Algebraic Ideas about Binomial Expansion, Stephanie explains how each piece of her physical geometric model for (a+b) cubed relates to the terms of the algebraic expansion. She then answers questions about her model that are raised by researchers Teri Perl, Carolyn Maher and her classroom teacher.
The problem as presented to Stephanie:
Explain your model of (a+b) cubed and how it relates to the algebraic expansion.
