Best used as a revision activity, this problem solving, thought provoking, fun experiment requires students to use independent thinking by using the merciless, brain provoking Y.O.Y.O. method (full explanation included). It comes complete with a student help sheet to help students who are struggling and also a full step by step solution for teachers and students alike if they need it. Class sets of springy toys can be bought very cheaply. I have used this in lessons and it really stretches students and makes them think. They even get to have fun with weird springy toys too! Spoon feeding must go! We need independent thinkers! Y.O.Y.O.

    Brilliant central idea. I thought the jokers were a fantastic addition

      Thanks! Much appreciated. Will work on some more. (if I ever get any time!) Jokers work well. Makes the little blighters think.
