I use Newsela for my AOWs since I can easily modify the levels of text. If you search "Quizzed Articles Only", those articles will have quizzes, also at the same varied lexile level as the text, always with four questions.
I use this rubric to assess my students on their weekly AoWs. I actually have entered this information into ForAllRubrics for even faster assessing.
My students must use my Close Reading Guidelines.
Thanks for looking!
