Educational Technology on Amazon

 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=February29 However it would be better to assign one of the student interactive activities below.

Here is the URL which will take them to a fantastic video that explains
why some years have an extra leap day and what it is for.
