  • Well done 9AM, Southam College! Good answer. There are more smart answers to this question lower down this page. The countdown clock above is a distractor, it leads the pupils to think that they are being asked to do a time consuming activity whereas the most efficient strategy would be to a mathematical operation not mentioned in the question at all.

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=May18

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