This document provides guidance for elementary school teachers participating in a Flat Classroom Project. It includes instructions on setting up accounts, posting reflections online, obtaining permission forms, creating classroom handshakes and avatars for the project platform Edmodo, filling in team grids to connect classes, and starting discussions around essential questions about similarities and differences among children around the world. Teachers are asked to work with students on creating a classroom handshake, choosing avatars or photos, and beginning discussions about assigned categories relating to topics like food, housing, and environment.
