NewsELA is the top of my list right now but like all thinks digital the options shift and change at random. You can change the reading level as well as store the articles you like. Most of the stories come with a quick comprehension quiz.

Dogo does not have the best library of news article, however, it does give students the opportunity to write and publish reviews of both books and movies. It’s a source to keep handy when your kids are writing opinion pieces.
