What are some good mathematical magazines and journals for undergraduates and/or high school students?

Question

I know only about Resonance published by Indian Academy of Sciences and I've read most of the content from it's math portion of all the issues.

Answer 1

AMS's journal is better. John Baez's stuff is quite interesting site, and I recommend Qiaochu Yuan's, too.

Answer 2

While it is not a journal or magazine, Introduction To Modern Mathematics by Helena Rasiowa is a great book. It covers introductory set theory, logic, and a bit of abstract algebra at the end.

It works through the proofs in detail so it is a very friendly read.
