Google Cast for Education is a free Chrome app that allows students and teachers to share their screens wirelessly from anywhere in the classroom. It works seamlessly with Google Classroom! This app allows a student to have the ability to share what is on his or her screen to the teacher's Google Cast app. The teacher's computer is linked to the projector where it can be shown to the entire class to share an idea, present to a large group, or respond to a problem or discussion. If your classroom has linked presentation screens simply slide the Google Cast presentation tab from your desktop to one of your presentation screen so students have the option to show work in small groups as well as the whole class.
