Decision+Making

Overview: Decision Making This unit continues to develop the algebraic reasoning in the unit Comparing Quantities. The students are introduced to using a coordinate graph as a method for representing the combinations within the scenarios and the idea of the fair exchange becomes a representation of the "slope" ratio. The idea of identifying combinations to fit constraints as regions on a graph is another focus of this unit. The student use these feasible regions to identify combinations that will solve a variety of problems with multiple constraints. Formal notation with inequalities is also reinforced in this unit.

Sec A: Students are introduced to the predominant context of the unit which involves making decisions on how to use a plot of land provided by the city. They need to investigate the feasability of building townhouses or houses (both with size restrictions) within the proposed development site. Sec B: The students are introduced to the idea of using a coordinate graph to represent the various combinations of townhouses and houses that will fit the land area constraint and identify the regions of the graph that contains additional combinations that fit the context. Sec C:
