I recently discovered [The College Mathematics Journal](http://www.maa.org/pubs/cmj.html) and enjoyed reading through some of the articles on fun applications of mathematics. I'd like to send some of the articles to my younger sister, a high school sophomore, but unfortunately most of them require calculus, a subject she hasn't studied yet.


Are there any other journals or websites that publish quality articles on applied math that a high school student taking pre-calculus could understand reasonably well?



Math journal for high school students?
An excellent journal published by the University of New South Wales (my alma mater!) is [Parabola](http://www.parabola.unsw.edu.au/content/about-us), aimed at interested secondary students.
