Clip 7/43: Standard 6: Attend to Precision Using Fractions Part 2C
Overview
Mathematically proficient students… try to use clear definitions in discussion with others and in their own reasoning.
Students continue to create sets of cards that match each other (Green: Set or Area Model, White: Verbal Representation, Dark Blue: Contextual / Word Problem, Yellow: Justification). Michelle Makinson asks pairs to explain the connections between the cards. She challenges students to persevere in grappling with a scenario working with 22/12. The class works with incomplete sets of 12 and incomplete wholes, recognizing that students seek to make connections to real life and become confused about how an improper fraction works in reality. The students create connections between the representations based on their observations of patterns and structures. This clip also relates to standard 7 (look for and make use of structure).
