TitleIntroducing Fraction Equivalence and an Exploration of Fraction Comparison, Clip 1 of 4: Equivalent fractions, a debate

DescriptionIn this clip, researcher Amy Martino leads a class discussion that centers on the task: If I call the orange rod one, what number name would I give two whites? Some students suggest the number name one fifth, while others suggest two tenths as an appropriate number name. The students then discuss which solution is correct, and whether it is possible for both solutions to be correct.
