Introduction to Inequalities: Working with Constraints
 
Big Idea: Before learning about systems of inequalities and equations, students jump in to a real world business problem and explore what it's like to work within certain constraints.

Emerging Pictures: Graphing Inequalities in Two Variables
 
Big Idea: Students plot points that satisfy and do not satisfy a linear inequality until they see a picture emerge in their graphs.

Two Methods, One Equation: Finding the Boundary Line
 
Big Idea: Hey, how did you find that line? Students examine two different ways to find the equations of boundary lines and work to understand why they are equivalent.

Introducing Inconsistent & Dependent Systems
 
Big Idea: Wait a second! Students explore what happens when there are no solutions that satisfy a system of equations as well as what happens when there are an infinite number of solutions.
