Clip 30/43: Standard 6: Attend to Precision Using Rate of Change Part 1C
Overview
Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning.
Antoinette Villarin returns to the academic language of the lesson: starting situation, initial value, rate of change. She asks students to use the sentence frames in pair-share conversations.
Antoinette shares a slide with new graphs showing rate of change and asks her students to use the sentence frames with their partners to describe what they see, using precise mathematical language as they do so.
This clip also relates to standard 3 (construct viable arguments & critique the reasoning of others).
