Pear Deck is a tool that can be used for a variety of educational options. I found a great video by Stacey Roshan (http://bit.ly/2YDAN3h) about how to use Pear Deck to make Google Slides presentations interactive. The video will show you how to install the Pear Deck add-on, how to add various types of slides, how to customize draggable slides and what the presentation looks like from both the teacher and student end.

Stacey also has a great follow up video with tips for using Pear Deck as a student paced, asynchronous option for learning.
