Pear Deck is a way to create interactive presentations with Google Slides.  Teachers can ask multiple choice questions to poll the class or check for understanding.  Teachers can also ask open ended questions to gather opinions and/or create closure activities. 

This video covers how to create an interactive slide show with Pear Deck.  It also covers the student view.  Pear Deck is free but has some features that require a subscription.
