 Patterns, Functions, and Algebra Focus: Linear Equations The student will a)   solve one-step inequalities in one variable; and b)   graph solutions to inequalities on the number line. HCPS Course 2 Curriculum Guide
 Essential Knowledge and Skills Represent and demonstrate steps in solving inequalities in one variable, using concrete materials, pictorial representations, and algebraic sentences. Graph solutions to inequalities on the number line. Identify a numerical value that satisfies the inequality. Essential Understandings How are the procedures for solving equations and inequalities the same? The procedures are the same except for the case when an inequality is multiplied or divided on both sides by a negative number. Then the inequality sign is changed from less than to greater than, or greater than to less than. How is the solution to an inequality different from that of a linear equation? In an inequality, there can be more than one value for the variable that makes the inequality true.

VDOE Interventions
1. VDOE Algebra Readiness Curriculum Companion: Investigating Patterns, Functions, and Algebra - The lessons focus on algebraic reasoning. Additionally, students learn to solve equations and inequalities, first by using manipulatives and then by working with symbols. They use modeling to collect data, and they learn to record data so that they can see the relationship that exists among tables, graphs, words, and equations. (pdf)
