What is it?A great often overlooked feature is Google Assistant, it works to varying degrees on Google Home, mobile devices and Chromebooks and can be a very useful addition to a classroom.
There is an ever increasing number of things you can ask Google just by talking to Google Assistant. On most Android phones it's just a case of saying 'Okay Google' or 'Hey Google' within ear shot of your phone and then asking your question.

If you're in posession of a phone that already has Google Assitant you wont need to install the app. If you don't have it here's a link to it on the Play Store and in the App Store
