DescriptionIn the ninth 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, the students note that the Truth Table for problem 6 does not conform to their general ideas for constructing the first 5 equations. Pairs of students share what they are observing about the table as presented below with researcher, Robert B. Davis. Romina, Brian, Michele I., and Ankur are featured. Researchers Carolyn Maher, Alice Alston and Amy Martino are observing.
