I like FRANK magazine, out of Australia. http://www.frankmag.com.au
It's free to download (PDF) online, from the website when you enter your email subscription. You can print them out then.

You might want to proof it to make sure it's 10-year-old-friendly, but I seem to remember it is. I guess it depends on your neice personally.
