Like Terms have something in common
they may have the same variable
or they may be constants
In either case it means we can add/subtract them

How many different kinds of terms do you see?
24
How many kinds of terms do we have?
25
Multiple Choice
How many kinds of terms are there?
26
Multiple Choice
Name the 3 kinds of terms you see?
27
Let’s rearrange the expression such that similar terms are adjacent or close to each other. This allows us to have a “laser” focus on which terms to add or subtract.
28
Rearrange so like terms are next to each other
identify the like terms (use color)
re-write the expression by taking the sign to the left of the term.
