I put together a nutshell chart comparing Nearpod, Pear Deck, and The Answer Pad because I see a lot of overlap between them. Please don't see the YES or NO as an endorsement or lack thereof. Sometimes a NO is a strength! These are all great tools that I encourage teachers to try and regularly use. I would be hard-pressed to choose any of them as the greatest.
I also just learned of a similar feedback tool called Formative. I hope to try that one out this week or next with my students and then I will add it to the above chart.
I will put together a similar chart about Socrative and Kahoot and a new favorite, Quizizz, soon.
