## Instructor Overview

# Lesson Overview

Students represent real-world situations using inequality statements that include a variable.

# Key Concepts

Inequality statements tell you whether values in a situation are greater than or less than a given number and also tell you whether values in the situation can be equal to that number or not.

The symbols < and > tell you that the unknown value(s) in a situation cannot be equal to a given number: the unknown value(s) are strictly greater than or less than the number. The inequality *x* < *y* means *x* must be less than *y*. The inequality *x* > *y* means *x* must be greater than *y*.

The symbols ≤ and ≥ tell you that the unknown value(s) in a situation can also be equal to a given number: the unknown value(s) are less than or equal to, or greater than or equal to, the number. The inequality *x* ≤ *y* means *x* is less than or equal to *y*. The inequality *x* ≥ *y* means *x* is greater than or equal to *y*.

# Goals and Learning Objectives

- Understand the inequality symbols <, >, ≤, and ≥.
- Write inequality statements for real-world situations.

ELL: When writing the summary, provide ELLs access to a dictionary and give them time to discuss their summary with a partner before writing, to help them organize their thoughts. Allow ELLs who share the same primary language to discuss in their native language if they wish.
