DescriptionIn the ninth of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions, the students continue to work on equations and figure out the general ideas for recognizing values that will make the statements true. The researcher, Robert B. Davis, first poses equations from problem 9 below and students quickly offer 5 and 6 as solutions. By the end of the discussion, two explanations for "secrets" for finding the values emerged. Davis, Jeff, Michele I., Matt, Stephanie and Milin are featured during the activity. Researchers Carolyn Maher, Alice Alston, Amy Martino, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Equations presented to the students:
9. (□ x □) - (11 x □) + 30 = 0
(□ x □) - (14 x □) + 13 = 0
Milin and Stephanie revisited Equation 1:
1. (□ x □) - (5 x □) + 6 = 0
