Some of the amazing book/education hashtags that I've been following & you could too are
#titletalk - meets last Sunday of the month from 8 to 9 online & participants discuss books around a certain theme. (i.e. professional books, picture books, sci-fi,...)
#bookaday - started by Donalynn Miller, author of Book Whisperer, teachers challenge themselves to read a book a day during the summer and share their ratings and titles with others.
#pb10for10 - every August teachers make blog posts of their 10 favourite picture books and post them to their blog & a host blog gathers the lists. You can check out all 126 posts at Cathy Mere's Jog The Web. Mine was about low down humour #59! Shocking that!
