Turn your computer screen into a shared screen. This is a great tool that I would recommend to any Chrome or Chromebook geared setup.
What is Google Cast for Education?Google Cast for Education is a free Chrome app that allows students and teachers to share their screens wirelessly from anywhere in the classroom. Cast for Education carries video and audio across complex school networks, has built-in controls for teachers, and works seamlessly with Google Classroom.
The Cast for Education app runs on the teacher’s computer that’s connected to the classroom projector, and it doesn't require new hardware. Teachers receive casts through the Cast for Education app, and students share their screens using the latest version of the Cast feature in Chrome.
