Subject: Calcudoku number puzzles for secondary school students

Dear all,

Last year I created a site with Calcudoku number puzzles,
aimed at secondary school students:

The puzzles are great for improving numeracy.

Students score points for solving puzzles, and are
ranked in weekly rankings, optionally by class/school.

The site is a bit quiet now because of the holidays.
So far, a couple of classes in the Netherlands signed up.

Feedback is welcome :-)
