DescriptionIn the second of six clips in Series 4 of Exploring Linear Functions, Ariel, a 7th grade student in an after-school enrichment program, defends his approach for finding values of Y for problem 4. When teacher/intern Gilberto Ladino asks for the value of Y when X is twenty, Ariel says thirty-eight. Researcher Keith Weber questions this result and Ariel explains his reasoning using a proportional argument. When Ladino asks him to check his solution by extending the table, Ariel modifies his strategy in order to explain the resulting Y-value of thirty-nine.
