Cast

Cast allows you to present your screen onto another person's computer. So, if a student wants to share their screen with the class via the TV monitor at the front of the room, they can. The teacher activates Cast on their Chrome browser, then the student (through Chrome) requests to present to the teacher's device. If the teacher approves it, the student can share a single tab, anything in Chrome, or their entire desktop to the front of the room.
