Laptops In Lessons

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=May31

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

One third of my family understand fractions while the other three quarters do not. I wonder which half of the family I am in!
