This document describes Corinne Filipiak's professional learning network (PLN) on Twitter. It explains that she first followed large education organizations to build her network, then expanded by following accounts those organizations followed. She highlights four accounts that have been particularly useful - @scholasticCDA for books and resources, @Pinterest for crafts and lessons, @mattBgomez for links from a kindergarten teacher, and @Bullying_org for anti-bullying resources. Corinne values her PLN for the easy access to shared knowledge and links on various elementary education topics.
