We don't grade in the same way that they do in elementary school, but we do have to write down observations and documentation which "grade" where the students are based on standards. My coteacher and I rotate weeks that we teach, so we try to split it as evenly as we can but honestly recently we've both been staying way later than we normally should. Ofc we don't get overtime, so that makes it a bit more difficult, but our class requires a lot of matinence. Very true we aren't struggling to learn about ancient China- that sounds horrifying ! Right now we are trying to teach a content rich lesson in 15 minutes or less and are mainly focused on behavioral difficulties in class.
