Instructor Overview

Students identify whether an inequality statement is true or false using a number line to support their reasoning.

Key Concepts

  • The meaning of m
  • The meaning of n > m is that n is located to the right of m on a number line. The inequality statement n > m is read “n is greater than m.”
  • To decide on the order of two numbers m and n, locate the numbers on a number line. If m is to the left of n, then m < n. If m is to the right of n, then m > n.

Goals and Learning Objectives

  • State whether an inequality is true or false.
  • Use a number line to prove that an inequality is true or false.
