Nearly 300 million kids are missing school worldwide because of the coronavirus outbreak, including some 54 million in the U.S. alone. That’s left parents scrambling for resources to help continue their children’s education, often while also working from home themselves — an almost insurmountable challenge. Today, the nonprofit media organization Common Sense is launching a site to help parents. Called Wide Open School (WideOpenSchool.org), it combines in one place the best educational resources for publishers, nonprofits and education companies.
