Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments: Transum.org/go/?Start=May6 However it would be better to assign one of the student interactive activities below. 

Here is the URL which will take them to a related student activity.

TELL LIES
In 1901, the British philosopher and mathematician Bertrand Russell uncovered a possible paradox that necessitated a modification to set theory. One version of Russell's Paradox involves a town with one male barber who, every day, shaves every man who doesn't shave himself, and no one else. Does the barber shave himself?

Interesting number paradox
Did you know that all numbers are interesting?
Proof: Assume there exists a set of uninteresting numbers. This set would have a smallest number, which is interesting because it is the smallest uninteresting number. But a number cannot be both interesting and uninteresting, so the assumption that there exists a set of uninteresting numbers must be wrong and hence, all numbers must be interesting.
The image above is inspired by another famous paradox. If you don't know it you could do a little research.
Clue: the man is known as Achilles.
