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:

Wow! This video was by far the most helpful I’ve watched on this material. By the time you put the last set of problems on the board I was solving them own my own! Most videos make the material “look” easy to do, with yours I can delete the “look” part!
