A selection of puzzles, many from the Junior or Intermediate Maths Challenges. Includes animated solutions. Good for promoting discussion and stimulating interest as starters, plenaries or extension. Powerpoint has clickable contents page to choose and move between puzzles.
The fact that the problems are sorted by topic is very useful and as each one is on a separate slide, they can be printed easily where that would be helpful. Thanks for taking the trouble to create this!
