Description of PearDeck from their web site.
Pear Deck Slides are very similar to a PowerPoint or Google Slides presentation. But instead of simply static, informational slides, you get to create Interactive Slides that let every student respond to your questions or prompts. When you present your Deck, students get a unique Join Code to enter your presentation right from their own devices.
Pear Deck Slides help you engage every student in every seat and give formative assessments, no matter what grade or subject you teach. Using Pear Deck will help you create an interactive and community-focused classroom that builds confidence and comprehension.
