Lesson objective: Fluently compare the inequality of rational numbers.

This lesson helps to build fluency with comparing rational numbers. Inequality symbols are used here because they specifically denote the relationship between rational numbers. This work develops students' understanding that three possible relationships exist between two rational numbers: a<b, a>b, or a=b.

Students engage in Mathematical Practice 2 (reason abstractly and quantitatively) as they determine the value of rational numbers and use symbols of inequality to establish a relationship between those values.

Key vocabulary:

• compare
• greater than
• inequality
• less than
• rational number
