On an adjacent lawn at Butternut Farm Apartments, as other children made chalk art on the asphalt, their older brother, James, 10, tossed bean bags into cornhole boards. The activities this week are part of a pilot program known as the Community Recess Van, which is helping children and families have a structured playtime outside their mostly virtual and remote classes. The program runs weekdays from 11:30 a.m. to 12:15 p.m.
