DescriptionIn the third of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions, researcher Robert B. Davis builds on the idea about equations with one variable and integers introduced in Clips One and Two. The class of 6th grade students is challenged to find the truth set for the open sentence printed below. Students respond and Davis keeps track of answers that work and those that don’t, based on substituting each proposed solution into the equation and evaluating the resulting numerical expression. The clip concludes with Davis distributing a set of problems for the students to investigate. Jeff, Michelle, Ankur, Matt and Milin are featured during the activity, responding to questions and directions from Davis. Researchers Carolyn Maher, Alice Alston, Amy Martino and Tom Purdy, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Equation One as presented to the students:
1. (□ x □) - (5 x □) + 6 = 0
