Mathematics
 Standard 8.Understands and applies basic and advanced properties of functions and algebra
  Level III [Grade 6-8]
   Benchmark 6
Solves simple inequalities and non-linear equations with rational number solutions, using concrete and informal methods
    Knowledge/skill statement 4
Understands the concept of an inequality
K(B2E,9,13;CE,189;PE,33;S2E,56)
    
Common Core Reference:
    6.EE.5, 6.EE.8, 7.EE.4; HS.A-REI.3
6.EE.5 Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.

6.EE.8   Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions;   represent solutions of such inequalities on number line diagrams.

7.EE.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

HS.A-REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
