Inequalities
	Exceeds expectations 4 pts	Proficient 3 pts	Basic Understanding 2 pts	Needs Improvement 1 pts
CED.A.1 Create equations and inequalities in one variable and use them to solve problems.	Exceeds expectations Can create and solve problems with 1-variable in complex equations and compound inequalities.	Proficient Create equations and inequalities in one variable, use them to solve problems	Basic Understanding Struggle to solve 1-variable equations independently or has difficulty creating equations and inequalities.	Needs Improvement Student cannot create or solve problems with 1-variable in equations and inequalities.
CED.A.3 Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context.	Exceeds expectations Student shows understanding of solving inequalities, graphing and shading.	Proficient Student uses solid lines and dotted lines or shading correctly but not both	Basic Understanding Student struggles with less than/greater than and equal to.	Needs Improvement Student does not shade the correct part of the graph.
REI.B.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.	Exceeds expectations Students can write and solve complex multi-step equations and inequalities in one variable.	Proficient Solve linear equations and inequalities in one variable.	Basic Understanding Student consistently struggles with the rules for solving equations that are multiple steps.	Needs Improvement Student cannot solve simple or multi-step equations.
REI.D.12 Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.	Exceeds expectations Graph the solutions to a linear inequality system in two variables as a half- planes.	Proficient Graph the solutions to a linear inequality, or system, in two variables as a half- plane(s)	Basic Understanding May be able to graph the linear inequality but consistently makes mistakes with line/shading.	Needs Improvement Cannot graph linear inequalities or systems of linear inequalities.
