In this download you will find two worksheets, a blackline master of the notes and a color copy of the notes. The "notes" consist of a colorful representation of the Real Number System with definitions of each sub-set and examples - along with, of course, the black and white copy for you to be able to run off for your students.

I have my students color in the sub-sets with colored pencils/crayons as are we are talking about them in class.
