A great idea to bring visuals into the classroom, from the Pinterest blog:
Not only are these Pinners sharing their knowledge and talents with other people, but they’re also using Pinterest as part of their classes. The teachers will be using their boards for everything from lesson plans, organizing class inspiration, showing off the results of projects (very useful for online education), class collaboration, and saving ideas for future classes. Because Pinterest is so strong in the Maker/Crafter community there is even a class on Pinning With Purpose: Telling Your Story On Pinterest!
For the DIY/Maker crowd, Skillshare has a craft semester that looks fun.
