These pages are meant to provide an introduction to some of the most easily
accessible logical/mathematical puzzles in a form that is easy to download and
Many of these puzzles need only paper & pencil, while others are physical. I
use the brightly-coloured plastic craft foam for the latter. Look for it in
dollar stores, craft stores, office supply stores, and department stores with a
crafts section. It takes a lot of careful cutting to make class sets – my mother
has been a tremendous help!
If you are a teacher, here

effective way to introduce most of these puzzles to your class.
