Clip 33/41: Standard 3: Construct Arguments & Critiques Using Rate of Change Part 3A
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 …. 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’s students continue their partner work, matching graphical representations of rates of change with each other.
In this clip, two different student pairs engage in mathematical discourse, comparing graphs to each other to discern which graph represents the top prism out of which the fluid is draining, and which represents the corresponding receptacle prism. Students offer ideas and defend their thinking to each other.
This clip also relates to standard 5 (use appropriate tools strategically).
