OpenEd has a large number of lesson plans and resources connected to Common Core Standards, and lets you create a virtual classroom — for free — and make student assignments.
I found their process of adding questions and an assessment to the assignments a bit confusing (you can see their video below), but it may just be because I tried it out late at night when my brain wasn’t on full cylinders.
