DescriptionIn the seventh of eleven clips from the first day of the Early Algebra Ideas 6th grade class sessions, the students look for patterns for finding a solution to the problems. As solutions are identified for each of the equations below, students posit that they “know why.” A discussion of the appropriateness of telling or keeping a "secret” to them follows. Students then whisper their reasoning to Davis. Jeff, Brian, Bobby, Ankur, Matt, Milin, and Romina are featured during the activity. Researchers Carolyn Maher, Alice Alston, Amy Martino and Tom Purdy, along with Marcia O’Brien, district supervisor, and Michael Poe, teacher, are observing.
Original equations completed during this clip:
2. (□ x □) - (16 x □) + 55 = 0
4. (□ x □) - (15 x □) + 26 = 0
5. (□ x □) - (6 x □) + 5 = 0
7. (□ x □) - (12 x □) + 20 = 0
8. (□ x □) - (12 x □) + 32 = 0
Additional Equations as presented to the students:
(□ x □) - (102 x □) + 200 = 0
(□ x □) - (14 x □) + 33 = 0
