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