I'm in the process of writing my first lesson that I plan to use Pear Deck (Geometry, section 7.2 - introduction to similar figures). As I'm planning, Andrew Stadel's blog pops up with this overview. This whole Twitter / blogging / MTBoS universe is pretty amazing.
Since I'm an infant yet at using Pear Deck, I'm curious to hear more about its versatility and specific ways others are using it. I hope to report back tomorrow with how things went.
