I am a huge fan of Lucy Calkins and have taken three courses that explored her Readers/Writer's Workshop principles and I've been doing WW and RW for about five years now. I recently reviewed her latest CCSS materials and our school purchased them as they were fantastic.
I'm not making any money on this Powerpoint, I just did a PD (Professional Development) for my school on the elements of WW (I did a mini-lesson which is not included) but it was more background information on what the purpose of the WW is and how to achieve it.
I just thought I'd share this product in case any others wanted some backgound information that was more visual than the copious information already out there. There's even some fun slides meant to just keep it light and easy, but as it's free I didn't edit those out. Anyhow, if it helps anyone, great!
