=Stage 1 - Identify Desired Results= Equations and Inequalities Grades 9-Diploma 2. Students solve families of equations and inequalities ||
 * **Establish Goals (MLR):** **(G)** ||
 * Maine Learning Results - Mathematics D. Algebra

//What understandings are desired?//
• algebraic equations with highest degree of one can be represented as lines. • there are multiple ways to solve a problem. ||
 * **//Students will understand that://** **(U)** ||
 * • the coordinate plane relates to ordered values in space.

//What essential questions will be considered?//
• How are equations of one degree represented as lines? • Why do we use multiple ways to solve a system of equations? ||
 * **Essential Questions:** **(Q)** ||
 * • How do different facets of the coordinate plane work?

//What key knowledge and skills will students acquire as a result of this unit?//
coordinate plane, ordered pair, independent variable, dependent variable, x and y axes, intercept, midpoint. • Key Facts: graphing methods, system solution methods, finding the slope of a line finding distance between two points. • Formulas: slope formula, distance formula slope-intercept form of a line, standard form of a line, point-slope form of a line, midpoint formula. || • predict the distance between two points • illustrate the location of a point based on its ordered pair • create the graph of a line • compare solution methods of systems of equations • relate a system of equations to a real world application • realize the solution to a system of linear equations is an ordered pair. ||
 * **//Students will know://** **(K)** || **//Students will be able to://** **(S)** ||
 * • Terminology: slope, system of equations,
