Content Area / MathematicsGrade/Course / HS Algebra 2
Unit Title / Unit 1: Linear Equations and Inequalities
Duration of Unit / 8 days
Priority Standards
HSA.CED.A.1Createequations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
HSA.CED.A.3
Representconstraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non-viable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.
Quality Core Standards
D.1. Expressions, Equations, and InequalitiesA. Solve linear inequalities containing absolute value.
B. Solve compound inequalities containing “and” and “or” and graph the solution set.
Note: Quality Core test bank includes problems with solutions in both set and interval notation.
Supporting Standards
