EASIER THAN YOU THINK...

Puzzles and Humour

I like mathematical puzzles (and mathematical humour).

They provide intellectual challenges and mental stimulation. They also help the puzzler to learn and develop good problem-solving techniques. These techniques can sometimes be used when solving strategy problems in real life and can certainly be used in other mathematical pursuits. I have hundreds, and possibly thousands, of puzzles to share with you. This represents a small start!

I have decided to bundle them in groups of twenty:

CCM Puzzle Collection #001 ~ Puzzles 001-020

  • Three Switches and a Light
  • A Knockout Tennis Competition
  • Covering a Modified Chessboard With Dominoes
  • Completing a Tour of Towns
  • Packing Eight Numerals Into Eight Squares
  • Counting the Number of Pathways to a Given Place
  • A Matter of Symmetry
  • Which Shape is MOST Different?
  • Riding a Falling Ladder
  • Divide an Obtuse-Angled Triangle into Seven Acute-Angled Triangles
  • Divide a Square into Ten Acute-Angled Triangles

 

Wow, how useful. … I always had a hard time with the chain rule, until I watched this video. The right presentation makes all the difference. Thank you very much. … These 20 second math videos you’ve graciously posted are excellent. I’m my little corner of the world, you’ve done great things.
