Clip 34/41: Standard 3: Construct Arguments & Critiques Using Rate of Change Part 3B
Overview
Mathematically proficient students…justify their conclusions, communicate them to others, and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose.
Antoinette Villarin asks her students to gather together the cards that they determined were matches for each other and to record a justification for each match on their recording sheet.
She explains that they will now engage in a gallery walk, in which one of the student partners will travel with a copy of their recording sheet of matches and justifications, comparing their thinking to that of other pairs, and the other partner will stay at their table and engage in conversation with visitors from other pairs.
Antoinette charges her students to be alert for differences in thinking and to make modifications to their recording sheets if necessary. She also reminds students to be especially attentive to other groups’ approaches to matching the three cards that had partial or missing information.
