I teach Maths to 10 - 13 year old children and these resources are aimed at them! I have also written a book called, "The Aliens have landed and 174 other problems" which is available from either Amazon or The Mathematical Association. It is full of mathematical puzzles. http://members.m-a.org.uk/Shop

This is a brief power point presentation to demonstrate the solution to the well know rope around the earth problem: if a rope goes all the way around the equator, how much more rope is needed to lift the rope exactly one metre above the surface of the earth?

The answer is an extraordinary and completely counter-intuitive one! It is in fact just 6.28 metres and it is exactly the same answer, whether the question is talking about a football or the earth!
