Abstract
(type = summary)
In the second clip in a series of seven from the third of seven interviews in which 8th grader Stephanie explores Early Algebraic Ideas about Binomial Expansion, the researcher, Carolyn Maher, asks how she would explain her ideas about area of squares to her younger sister. When Stephanie indicates that she would revisit basic ideas about units and square units, Maher offers her base-ten blocks from which Stephanie selects and uses a cubic unit and a square "flat" composed of 100 cubic units. When asked how she would represent a square with side length "a", Stephanie selects from a set of plastic shapes one that most closely approximates a square, noting that the side has no marked units and so can be considered to represent the general case.
The problem as presented to Stephanie:
How could you use squared concrete materials to explain about the area of a square to someone who has not studied area?
