Standard 5: Use Appropriate Tools Strategically

Clip 6/13: Standard 5: Use Appropriate Tools Strategically Using Rate of Change Part 3A


Mathematically proficient students consider the available tools when solving a mathematical problem.

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 3 (construct viable arguments & critique the reasoning of others).
