Are you familiar with videos from Teaching Channel?
If you haven't signed up yet you should go do it now! They have videos of lessons and quick tips from teachers. I love the fact that most videos also have the pages they used with the students and pictures of different things from the lesson.
My most recent favorite is the video that discusses Keep It or Junk It. I loved this idea and will be trying with my students soon. I also created some posters to display in my classroom. Feel free to use them if you want to try this as well.
