TitleEarly algebra ideas involving two variables, Clip 16 of 18: Working on problems 8 and 9

PublisherNew Brunswick, NJ: Robert B. Davis Institute for Learning, , c1993-10-01

DescriptionIn the sixteenth of 18 clips from Early Algebra Ideas Involving Two Variables on the second of two consecutive classroom sessions with the class of 6th grade students, the students are looking for relationships among the values in the tables that will help them to find equations for problems 8 and 9. Researcher Robert B. Davis points out to the group that they are to construct equations that do not depend on knowing the value of the "triangle". Rather, each equation should be in a form such that substituting a value for each "box" in the left side of the equation will produce the corresponding value for "triangle". Michele R., Jeff, Amy-Lynn, Robert, Brian, Romina, Stephanie and Matt are featured. Researchers Carolyn Maher, Alice Alston and Amy Martino are observing.
