Every weekday four buses head into the New Delhi slums to give the children of migrants, laborers, rag-pickers and scavengers a chance at an education they might not get otherwise.

Each bus goes to two locations a day, setting up an onboard classroom to give about 50 children at a time basic lessons in math, body parts, English and Hindi, along with daily meals. Ages range from 3 to 13, and some activity-based lessons are held outside.

These "Hope Buses" of nonprofit group TejasAsia are one of several grassroots initiatives in India helping to fill the education gap caused by the coronavirus pandemic. Another such initiative delivers lessons by loudspeaker to children in rural areas.
