N. W. D. Puzzle
In 2018 Odette De Meulemeester requested
this puzzle.
It honors the Nationale Wiskunde Dagen,
an annual conference of mathematics teachers in Utrecht.
- Download it in Portable Document Format (P.D.F.) here:
[A4]
[Letter Size].
You will need either a printer or a program
(like Adobe Acrobat Reader)
that can read a P.D.F. file.
- Print it on card stock, preferably in color.
If you have no card stock, paper will do.
- Cut out the pieces.
- Fit the nine pieces together without overlapping
to form a 6×6 square.
The square will contain holes.
You may not flip the pieces over.
Good luck!
