DescriptionIn the second of five clips in Series Two of Exploring Linear Functions, researcher Arthur Powell challenges 7th graders,Yonny and Brandon, 7th to find a rule for Guess My Rule problem 2. Noticing the same pattern of differences that they had used for problem 1, the boys quickly gave that as their rule and determined values up to ten. When asked to try a different strategy for the rule when X is twenty, the boys predict that Y would be forty-five, which they found by doubling ten and adding twenty-five, which was the Y value for ten to get forty-five. When asked if there was another way, they return to their table and continue adding two to each value of Y for each successive value of X. They are pleased when they find that the value for twenty is indeed forty-five. Teacher Alan Hiba is observing.
