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=November25 However it would be better to assign one of the student interactive activities below. 

Here is the URL which will take them to a student activity involving mathematical words.
