The history magazine American Heritage published an excellent article about the New York City tenement museum in April 2000. A xerox copy with all the photos is available from HCC library, but the text (with photos omitted) is available online through the GALE database.
The February, 2004 issue of Cobblestone magazine is all about tenements. It is in child-friendly language. You can access all of these articles online (outside of the building you will need the GALE password) by clicking on the articles below or clicking on this link.
*The articles are much, much better in print because there are excellent photos. Please ask for a copy of the printed magazine from the library.*
Excellent photographs with captions, plus interviews (might be good for a DBQ).
New York City's Tenement Museum is a fabulous place to visit, both in real life and online. Here are some great resources on their site.
