Not all expressions are created equal, but we can still use some algebra to compare unequal numbers, variables, and/or expressions in interesting ways, like inequalities. You've heard of "greater than" and "less than," right? Terrific! First we'll express inequalities on a number line and then write them using information in word problems. Common Core Standard: 6.EE.B.8
We've been taking a lot of equalities. What about when the relationships between numbers need to be expressed as inequalities? For example, less/greater than and/or equal to? How can we represent that idea on a number line?
