Snowflake artwork adorn windows at the new Sandy Hook Elementary School, on the day before the first day of classes Jan. 2 in Monroe, Conn. Three months after the Newtown massacre, children and teachers who survived remain on edge. Signs in the new school ask people to close doors softly and not to drag objects across the floor during school hours, in an effort to help keep students and faculty at the school as calm as possible.
