Vocabulary • A mathematical sentence indicating two quantities are not equal. Inequality- • The distance between a number and 0 on a number line. Absolute Value- Any number greater than 0. They can be written with or without the + sign and appear to the right or above the 0. Positive Integer- Negative Integer - 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. Rational Number - Aline on which numbers are marked at intervals, used to illustrate simple numerical operations. Number Line -
I Can…. 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 ≤. Example:

I Can…. 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 Inequalities Essential 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
