For most kids, Martin Luther King Jr. Day means a day off school.

But Wendy Spencer, who heads the Corporation for National and Community Service (CNCS), would like kids to start thinking about the holiday as a “day on.”

Since 1994, the CNCS has been celebrating King’s birthday by organizing a national day of service. Each year, hundreds of thousands of participants spend the day volunteering at parks, food pantries, homeless shelters, community gardens, hospitals and other places.

“Dr. King was so much about service and giving back and community gatherings and bringing people together from all walks of life,” Spencer said. “What better way to honor him than . . . by making it a day of service that lives out what he preached about?”

Are you feeling inspired to volunteer? Here are three opportunities for kids to participate in the MLK Day of Service. All events take place January 19. (Always ask a parent before going online.)
