I hope to have some more information and neat tricks, etc. for you from CUE in the coming weeks as I disseminate and try out different things, but we're going through WASC right now, so things are a little crazy, and I'm a little behind in my grading.
One thing I do want to share that I've tried out with my 11th grade students is Pear Deck. Pear Deck allows you to broadcast your presentation to and integrate interaction with the students and their devices (Chromebooks in my case). So, instead of students following along on the screen with your PowerPoint or Google Slide, you can have them following along directly on their own screen (works with anything that has a web browser) and even have them answer questions that you can then project up onto the board.
Here are some videos about it that I found.
There is a free version and a premium version. I'm currently doing a 30 day trial of the premium version to see if it will be worth the cost. I'll give my opinion on it when I make the decision.
