Now let’s create a double bubble map to compare and contrast expressions and equations.

Expressions Equations

Now let’s take what we’ve learned and read

an expression or an equation and write it

numerically!

It’s easy! Waaay easier

than what that guy is doing….

Whoaaa….whoa! This is

tricky….but math is NOT!
