Hello all,

Last year I created a site with "Calcudoku" number puzzles,

aimed at secondary school students:

The puzzles are fun to do, and 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 :-)

thanks,

Patrick

Hi pmin00;

Welcome to the forum. I have placed the link for you since it is free and math related.

**In mathematics, you don't understand things. You just get used to them.Of course that result can be rigorously obtained, but who cares?Combinatorics is Algebra and Algebra is Combinatorics.**
