Clip 31/41: Standard 3: Construct Arguments & Critiques Using Rate of Change Part 1D
Overview
Mathematically proficient students…make conjectures and build a logical progression of statements to explore the truth of their conjectures…. They justify their conclusions, communicate them to others, and respond to the arguments of others…. Students at all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments.
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 relate to standard 6 (attend to precision).
