Interpreting and Writing Inequalities
Essential Understanding: An inequality is a mathematical sentence that compares quantities using the symbols >, <, ≥, and ≤.
Example:

Writing and Graphing Inequalities
Essential Understanding: • Inequalities can be graphed on a number line
using an open or a closed dot and a ray ( )• An open dot means the number is not included
(used with < and > symbols) • A closed dot means the number is included (used with ≤ and ≥)Examples:

I Can….Determine the value of a variable to make an
inequality true.

Solving InequalitiesEssential Understanding:Inequalities can be solved by finding values for the variable that make the inequality true.
Examples: X +2 < 8
8-2 = 6 or 2 + 6 = 8
X must be a number less than 6 to make this sentence true. Therefore, any number less than 5 would make the sentence true x < 6 or x ≤ 5

Solving One-Step Inequalities
Essential Understanding:
Addition and subtraction and multiplication and division properties can be used to solve inequalities.• If the same number is added or subtracted from each side of an
inequality, the inequality remains true.• If the same positive number is multiplied or divided from each
side of an inequality, the inequality remains true.
Examples:3 < 6 3 < 6 x > 6 x > 6
