Number Line Inequalities Review

• I can write inequalities from given graphs on the number line by writing using the correct variable, inequality symbol, and rational number.

• I can explain how to graph inequalities from a given inequality statement by graphing the correct number on the number line, filled in or empty circle at this number, and correct direction of shading and arrow.

• I can write an inequality statement for a given real-life situation by writing the correct number and inequality symbol to represent the scenario.

Inequalities Review

​Inequality: A mathematical sentence that compares expressions using <, >, ≤, or ≥ symbols.
Variable: A symbol, usually a letter, used to represent an unknown value.
Solution: A value that makes an inequality true.
Graph: A visual representation of an inequality on a number line.

Key Vocab

• My inequality statements have the correct symbol in the correct direction, the given rational number, and a variable.

• My graphs of inequalities have the correct circle on the given number and direction of shading.
