Tween Tribune is set up much like Newsela--except that it's free! Yeah! Teachers can create free accounts/classes and have their students join. Current event articles are offered in 3-4 Lexile levels with comprehension check quizzes. Many articles are also offered in Spanish. If you create a teacher account, the Smithsonian loads you up with more free goodies under the "teacher" tab--lesson plans, text sets, photos, etc.
Screencast-O-Matic is now available to students via the Software Center. This is an oldie, but it's a goodie. Use it to create and share screen recordings--students can explain their learning, make movies out of PowerPoints, make tutorials for other students. Teachers can use it for flipping lessons and quick instructions (especially if they may be absent from the class for a day or so).

Teach your students using their favorite TV shows and movies. Browse through the library of clips by clicking on browse and choosing all clips. A menu on the right side will appear with discipline-specific topics. Accounts are free; many clips come with discussion questions and can be embedded. Clips with a "v" in the corner will most likely be blocked for students.
