DescriptionIn the sixth of six clips in Series 4 of Exploring Linear Functions, Ariel, a 7th grade student in an after-school enrichment program, revisits his work on Guess my Rule problem 4 with teacher/intern Gilberto Ladino. After successfully coming up with the rule, "times 3 minus 8", for problem 5 (See Early Algebra: Investigating Linear Functions: Series 4, Clip 5.), he looks back over his table for problem 4 and tries several different numbers as multipliers, predicting that he should subtract 1 from the product. After several trials, Ariel announces that the rule is "times 2 minus 1".
