DescriptionIn the tenth of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions,
all but three of the students claim to know the general "secrets" for finding values that make a given equation true. Researcher Robert B. Davis challenges the three students, Michele I., Jeff and Michael to solve the equation below. When they find one value that works, they are satisfied. Finally, Ankur articulates the general rules about adding and multiplying the two numbers to find the constant terms in the equation. Michele I., Jeff, Michael, Romina, Ankur, Brian and Bobby are featured during the activity. Researchers Carolyn Maher, Alice Alston and Amy Martino, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Final equations presented to the students:
(□ x □) - (102 x □) + 200 = 0
(□ x □) - (8 x □) + 15 = 0
