Clip 7/13: Standard 2: Reason Abstractly & Quantitatively Using Fractions Part 3


Mathematically proficient students make sense of quantities and their relationships in problem situations.

Michelle Kious works with her 5th grade students on understanding multiple representations of mixed numbers. In this clip, her students engage in a card sort, matching different representations of mixed numbers. She helps them name and make explicit the correspondences between the representations, e.g. “So you're going to say ‘Card C,’ and then say the number, “is equivalent to,” and then I want you to name the fraction. And then say, ‘Because it shows ...’ and explain to your partner what it shows.“
