Clip 28/43: Standard 6: Attend to Precision Using Algebraic Equations Part A
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.
Disston and his students share their insights into the day's lesson and reflect on what they learned.
