Book Recommendation: Teach Like a Champion 2.0

An encyclopedia of techniques for a variety of actions you can take in the classroom from the seemingly odd way to make paper passing more efficient (it actually saves hours of instructional time) to ways to increase participation in the classroom.  

It's one of those books that you may not read every week or even every month, but it's one worth keeping on the shelf for periodic review and for browsing different strategies when you need a new tool in your kit.
