Essential Understandings
Concrete:
- Manipulate lines on a graph to show no solution (parallel).
- Manipulate lines on a graph to show one solution (point of intersection).
- Manipulate lines on a graph to show infinite solutions (the same line).
- Locate coordinate pairs.
- Use tools to varify the solution of a non-linear system (graphing calculator, graphing software). Click Here
- Understand the following concepts and vocabulary: linear, non-linear, equation, substitution, system of equations, qualities, solutions, intersection, skew.
- Understand that substitution allows for solving the equation one variable at a time.

Cluster:
Solve systems of equations. (Algebra 1 - Additional Cluster) (Algebra 2 - Additional Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
