The Adamus children are among tens of thousands of students across the nation who resumed in-person school Monday for the first time since March. Parents in Louisiana, Mississippi and Tennessee are also among those navigating the new academic year this week. Many schools that are recommencing in-person instruction are also giving parents a stay-at-home virtual option; Adamus, like many other parents, decided against that. Other schools are planning a hybrid approach, with youngsters alternating between in-person classes and online learning. But an uptick in COVID-19 cases in many states has prompted districts to scrap in-person classes at least for the start of the school year, including Los Angeles, Philadelphia and Washington.
