Then check out Newsela.

Every day Newsela publishes topical, high-interest news articles for kids in grades 2-12; think of it as a New York Times for young readers.  One of its distinguishing features is that all articles are available at five different levels of text complexity.  Newsela sorts the levels using the Lexile Level Measures (you will see them to the right of each article) which are numerical. To learn how Lexile Levels Convert to PS11’s alphabetic levels, check this out.

Newsela also provides writing prompts (which are editable) and quizzes for each article. And as if that weren’t enough, the articles are also available in Spanish.
