DescriptionIn the fourth of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions, the students work in small groups to find and record solutions for the first two of a series of open sentences that have been presented as a worksheet by the researcher, Robert B. Davis. As the students test different values in the equations, Davis keeps track on the white board of answers that the students propose after testing each suggested value. Davis records correct solutions. Jeff, Michelle, Ankur, Matt and Milin are featured, researchers Carolyn Maher, Alice Alston, Amy Martino and Tom Purdy, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Equations Two and Three as presented to the students:
2. (□ x □) - (16 x □) + 55 = 0
3. (□ x □) - (10 x □) + 21 = 0
