Google Hangouts is a service that lets people communicate through text, voice, or video chat. Hangouts is available either as a feature of Google+ and Gmail or as it’s own app.
All Perry Township Schools staff members have access to Google Hangouts. This tool is not available to individual students, but teachers can use Hangouts to connect their class with people across the hall or across the world.
