DescriptionIn the fifth of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions, the students work together to find the truth set for equation four on the worksheet recorded below. Milin suggests 2, substitutes it into the equation and evaluates the result. Davis encourages the class to do the calculation and, when they agree that the resulting equation is true, records 2 as one value in the truth set. Researchers Carolyn Maher, Alice Alston, Amy Martino and Tom Purdy, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Equation Four as presented to the students:
4. (□ x □) - (15 x □) + 26 = 0
