Essential Questions:
Which package will get me more music from iTunes: a monthly membership with unlimited downloads or buying songs individually?
You are eligible for a cell phone upgrade; you need to find the best package for your money, what is it?
Big Ideas:
Analyze and solve pairs of linear equations.
Unit 3 instructional time will be focused on the following power standards:
8.EE.C.8: Analyze and solve pairs of simultaneous linear equations.
8.EE.C.8.A: Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
8.EE.C.8.B: Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection.
8.EE.C.8.C: Solve realworld and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.
Unit 3 instruction will be supported by the following standard:
8.EE.C.7: Solve linear equations in one variable
