Reflection: Complex Tasks More Linear Programming - Section 2: Share


We discussed different methods for graphing the system of inequalities for the Fruit Grower problem. Some students were solving the equations for one variable and then using their graphing calculator, but then they had to adjust the windows and were not seeing the full picture of the graph. This was misleading and caused some errant solutions.

Other students were just sketching the graphing using the x- and y-intercepts, and then manually finding the intersection points algebraically. This seemed to work well but these students were having a tough time deciding which intersection points were part of the feasible region.

No method was perfect, but I found that it was a good idea to give students options so they can choose the one that is best for them.
