Whole group discussion: Constraints. The class begins by generating a descriptive, factual list about the constraints.
The previous night's homework: look at the original constraints and try to figure out which ones can be crossed out. |

Whole group discussion: Eliminating constraints.
Students approach the board to explain which constraints can be eliminated and why. Keeping their train of thought proves to be very challenging, and the class is patient and supportive.
Students at the board include Ashley, Russell & Simon (who both lose their thoughts at the board and sit down to try to remember), and Gregg. I ask Gregg to repeat his thoughts because she gets confused. Ashley joins him at the board to help explain. I help the class see that Ashley has most frequently been using the equations with the most variables and the equalities. |
