We already know the bad news: Bored kids, harried parents, days when time slows to a standstill. Here’s the good news: Museums, libraries, arts organizations, private companies, celebrities and many others are stepping up and creating online content for kids or offering free access to existing resources. Many more online portals and entertaining apps have been with us all along but never seemed more relevant. To give parents a sense of what’s out there, we’ve compiled resources in 10 categories: education, travel, reading, mental wellness, music, art, physical activity, theater and dance, languages and entertainment. So don’t just sit there — learn how to wrap a mummy, take a virtual train ride, conjugate Spanish verbs or watch a Metropolitan Opera performance. Just because time is at a standstill doesn’t mean you have to be.
