A big shout-out to my friend and colleague, Dawn Reynolds, for snagging some great sites as sources of short web-based articles for kids. Last year, Dawn and I collaborated on a reciprocal teaching reading project, we have been scouring the Internet to find short articles (mostly non-fiction) to practice the reciprocal teaching strategies. Once we find a great short article (preferrably related to the science and social studies content) we use http://www.joliprint.com/ to convert the web-based article into a pdf document (and get rid of the web junk on the left and right of the webpage.
Here are some other great sources for finding informational text online:
The Internet Public Library (newspapers & magazines)
Online Newspapers (6-12)
Newsmap - Visual News (like Wordle for news) (6-12)
