Rules of Contests

We offer 5-6 contests per year. Each contest is graded individually, and then at the end of the year the Year Winners are also selected as a result of their cumulative scores.

Winners are selected by grade level (i.e. there are separate winners from grade 2 and grade 3 even though they are offered the same contest).

It is important that contestants show their solutions. A correct answer without an explanation is awarded 50% of the possible points. Only a correct answer with correct explanation will lead to a 100% score. Partial explanations result in partial scores.

Note: only MWSM students and their relatives are eligible for the prizes – although of course everyone is welcome to send solutions.

About Our Own Puzzle Contests

Puzzles help train out-of-the-box thinking, and keep up interest in math. They frequently tie together many unrelated things children learn in the regular program, and most certainly they train logic.

We also offer puzzles to parents, grandparents, aunts and uncles of our students. It adds a bit of a completion between the generations – and we must say parents are trailing behind their kids as a rule!

Our Puzzle Contests are now in their 9th year and growing. Join us and enjoy!

Puzzle us!

Our puzzles come from a variety of sources – old books, old memories, old and new friends – and many of our own making.

We always welcome new additions – so if you know of good ones – please send them our way to
