Our tech director sends us emails now and then with some cool tools to try out. This is one I decided to try. It is called EdShelf.  It is a place to curate apps for particular purposes. For example, I created an EdShelf for formative assessment apps. You can follow fellow shelf creators and others can follow you.  I also like it because you can print out QR codes or URLs directly from the shelf.

See what you think of it.
