Abstract (type = summary)
In the sixth 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 uses her numerical representation of the expansion of (3+7) cubed and develops a parallel expansion for (a+b) cubed. She uses the distributive property to write out each term and then simplifies and collects like terms, explaining each step of the process to researcher Carolyn Maher.
The problem as presented to Stephanie:
For the equation (a+b) cubed = (a+b) (a cubed + 2ab + b cubed), simplify (a+b) (a cubed + 2ab + b cubed).
