DescriptionIn the first of six clips in Series 4 of Exploring Linear Functions, Ariel and James, 7th grade students in an after-school enrichment program, are asked to find a "rule" for the Truth Table for Guess My Rule problem 4. The camera follows Ariel as he recognizes a recursive pattern of successive numbers added to sequential values of X that will result in the corresponding values of Y. He describes this pattern as "adding one to the Y" and, announcing that this is his rule, illustrates his idea by extending the table for values of X up to ten. He writes each successive addend beside the Y value that it has produced. As teacher/intern Gilberto Ladino questions Ariel about his process, Yonny shows Ariel the table and rule that he has developed to solve James' Problem, which Ariel had solved earlier. (See Clip 7 of Linear Equation: Series 3 to follow Yonny's work on James problem. Ariel can be observed working on James problem in Linear Equations: Series 1, Clips 7 and 8.)
