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=May24 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.
Which clockface is the odd one out?
The answer can be found by looking closely at the roman numerals used.
The clock on the right uses IIII for the number 4 while the other two clocks use IV.
Investigate which system of numbers is most common on clocks in your school, home or place of work.
