This foldable orgaizes the classification of numbers within the real number system. I have the students write the definiton/ or use set notation on the back of each tab. On the inside of the foldable, there is a Venn Diagram, which provides students with another representation of the each of the sets of numbers and their relationship to one another. We also include examples of each set inside of the Venn Diagram.
An answer key is included!
