Google Keep is one of Google's most powerful, but frequently overlooked organizational tools available. As educators (or any professional) we have to constantly navigate the requirements and deadlines of our work as well as everything that must be accomplished in our personal lives! Add about 30 kids in your classroom on top of that and you wonder why Teachers feel overwhelmed!
As an administrator, I constantly see sticky notes posted... EVERYWHERE! On Promethean boards, on the wall, on binders, and desks, and on laptops (both on the desktop digitally AND physically stuck on). Not only can Google Keep, organize ALL those notes for you, it can turn them into lists, allow you to add images or voice notes, even set up recurring reminders so you'll never forget things that need to get accomplished!
