Abstract (type = summary)
In the second clip in a series of eleven from the sixth of seven interviews, 8th grader Stephanie continues her exploration of early algebraic ideas about binomial expansion with researchers Carolyn Maher and Robert Speiser. After reviewing the meaning of the combinatorics notation, Stephanie begins to logically build sets of Unifix towers of different heights when selecting from green and blue cubes. She asserts that there would be exactly two towers that are one-cube tall and positions these two cubes as a first row. She then constructs the four towers that could be generated from those two by adding either a green or a blue cube onto the original cubes and positions them as a second row. Stephanie then repeats this process to produce a third row of towers 3-cubes tall. Finally, she rebuilds the set of towers 4-cubes tall that she had built earlier and positions them in a fourth row, according to the correspondence between each of the 8 towers in row 3 with the pair that it could have generated
The problems, as generated by Stephanie for her discussion with the researchers:
Explain the meaning of the symbolic notation for selecting a particular number of items from a set of items.
Beginning with towers one cube tall, build each successive set of towers from towers that are two-cubes tall through towers that are 4-cubes tall, showing how each successive set of towers is generated from the row with height of one fewer cube.
