Abstract
(type = summary)
In the first clip in a series of seven from the third of seven interviews in which 8th grader Stephanie explores Early Algebraic Ideas about Binomial Expansion, Stephanie arrives with several pages of notes that she had written about her work in the first two interviews. When the researcher, Carolyn Maher, asks Stephanie to review her work, she explains that the focus of the earlier sessions had been to determine what was (in expanded form) the square of the quantity (a+b). She notes that her first approach was symbolic using the distributive property and that she tested her proposed solutions by substituting numbers for the variables and then by drawing a geometric model.
The problem as presented to Stephanie:
Review what you have written about finding the square of the quantity (a+b).
