DescriptionIn the sixth of eight clips in Series One of Exploring Linear Functions, researcher Evelyn Hanna asks James and Ariel to figure out the Y value for Guess My Rule problem 3 if the value of X is eighty-four. While James hesitates because his strategy has been recursive, Ariel uses his rule of 3 times X plus 1. Ariel then calculates a Y value for X = 1,250 but expresses concern about his two earlier results for X = 25 that were different. The session concludes with researcher Hanna challenging the boys to create their own Guess My Rule problem.
