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=March5 However it would be better to assign one of the student interactive activities below. |

Now the prices of the letters are defined by prime numbers (A = 2, B = 3, C = 5 etc) and the price of a word is the product of the letters it contains.

What mathematical words might cost:
£6.10
£26.84
£2726.90
