The group was approximately 25 people in the conference room at Main office in WCSD Pa. I implemented the Unit organizer (with Erin Eighmy) over the entire 6 hour training, stopping between sections to discuss transitions and major concepts. I found that the teachers were excited to see the "big picture" of how all of the LETRS modules are connected. This module is a little lighter, so it was easier to implement the organizer, without sacrificing the material.
