Any number greater than 0. They can be written with or without the + sign and appear to the right or above the 0.

Any number less than 0. They are written with a – sign and appear to the left or below 0

Any number that can be written as a fraction.

A line on which numbers are marked at intervals, used to illustrate simple numerical operations.

Interpret statements of inequality as statements

about the relative position of two numbers

on a number line diagram.

Interpreting and Writing Inequalities

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

Graph Inequalities

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

I Can….

Solve one-step inequalities.

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
