DescriptionIn the sixth of seven clips in Series 3 of Exploring Linear Functions: Graphing and sharing Guess My Rule problems, a group of 7th grade boys in an after-school enrichment class are trying to find a general rule that will work for the problem that James posed in Clip 5 of this series. Brandon first claims to know the rule and describes it as the pattern where the values of X are increasing by one and the values of Y are increasing by three. Researchers Keith Weber, Prashant Baldev and teacher/intern Lou Pedrick affirm the pattern that he has described but ask him whether he can find a relationship between each value of X with its corresponding value of Y. When Brandon says that he does not understand what they mean, the researchers show him the transparency for problem 1 with Ariel's rule, Y=2X+1, and the examples that Ariel had given to justify his rule. Brandon exclaims: "Oh!" and begins to analyze the X and Y values for James' problem. He explains his ideas to researcher Allison McCulloch, and show how his rule works for all the values in the table. He then justifies his conclusions to researcher Weber and, after explaining the rule for the values on the table, gives the Y values for X=100 and for X=10.
