Everyslide - Mirror iPad Screen to Students

Everyslide is a great tool for teachers to use when they want to control the content their students see on their devices.  Teachers accounts are free and the setup is super simple.  Just drop a PDF or a Power Point onto the website and it uploads the file and gives you a six-code for the students to enter.  They open Safari (not supported in Chrome) and enter the code and they're connected to your device.  When you change pages or slides it changes on their end too.  With minimal setup you can bring back some control to your classroom.
