American Association of School Librarians Best websites and apps

I was hoping to attend this Iowa Library Association presentation on the AASL best websites and apps in October to learn a little, but when a colleague had to cancel in order to conduct professional development at her own school, I ended giving the presentation and learning a lot!

Information about each of the sites is linked using one of the best website tools, Thinglink. Any of them look interesting? I'll be more than (h)appy to help!
