The hallways of Milwaukee School of Languages were empty Monday morning.
There were no students excitedly catching up on their busy summer break. No lockers slamming or announcements over the loudspeaker. No one running to get to class on time.
Spanish teacher Marielle Rivera sat in a sunny corner of her classroom, flags of the United States and Latin American countries overhead and Black Lives Matter posters on the front of her desk. And she laid out her expectations for the school year for her eighth-grade students, whose faces she sees on the computer screens in front of her.
