DescriptionIn the fourteenth of 18 clips from Early Algebra Ideas Involving Two Variables on the second of two consecutive classroom sessions with the class of 6th grade students, a number of the students present their equations for Problem 6 (printed below) to the researcher, Robert B. Davis. He notes that when mathematicians are satisfied with a "secret" they publish it to the community, suggests that this might be the time for the Table 6 equation to be published, and asks Michele I. and Ankur to present. The pair of students write the equation (□ x _) + 1 = ∆ on the whiteboard and explain that, for any value of "box", the same value must be entered in on the line in order to get the value for the "triangle". Michele asks the class what shape should replace the line (_) and they respond that the shape should be another "box". Michele, and others in the class, refer to this as "the code". Jeff, Romina, Brian, Ankur and Michele I. are featured. Researchers Carolyn Maher, Alice Alston and Amy Martino are observing.
