Product Description
Understanding different forms for lines gives students additional power to develop and expand their tools for solving systems of linear equations. This mission is aligned with Common Core Standards: 8.EE.8, HSA.REI.C.6.

How awesome are the substitution and elimination methods for solving systems? Truly awesome, because they are grounded in some essential truths about functions and equations! Students will get a guided exploration of slope-intercept form and standard form for a line. Then they will explore the rational for the substitution and elimination methods for solving a system. Finally, they get guided practice using both methods. Thorough, deep and useful!

The zip file includes:
★The mission. (12 pages).
★A two-page Quick Start guide for teachers. Detailed and helpful!

The mission includes:
•Graphing in slope-intercept form
•Development of standard form based on equivalent equations.
•Rational and guided practice, substitution and elimination methods.
•Carefully crafted practice problems.
•Practice choosing the most efficient method.

We all have an innate curiosity about how the world works. We are wired to experiment at the edges of our knowledge, to look for patterns and to draw conclusions. Mistakes are the welcome surprises which help us refine the experiment. In a student-centered classroom, students collaborate to ask questions, gather data, interpret results and articulate understanding. Success at the edge of knowledge demands persistence and creativity. Courage To Core provides a context for students to work together to become the agents of their success and the owners of their cognition.
