• To get the most of this activity it needs to be repeated! Getting the correct answer first time can be done by trial and improvement. If the activity is repeated (refresh this page or press the F5 key for Internet Explorer) and the challenge is to be first with the correct answer a better strategy is required encourage students to think about the problem in a different way.

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

 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=September20 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.
